Urgent help needed on Emit Dynamic Assembly

Hi,All MS Tech Gurus:
I need your help!!! It is the second time I post this message, I need get
some feedback ASAP, Please Help!!
Thanks a lot in advance.
John

I have a csharp method, using emit to dynamically generate classes & method
depends on the meta table in the database,here is my situation
1) In One method I generated the code Dynamic IL Code (Depends on the data
pass to it), The generated code works for one dataset but does not work for
another one, when it does not work, it generate the following error
Object reference not set to an instance of an object
2) The generate method which is not working on one machine is working fine
on a differennt computer with not code change
3) The generate method which is not working on one machine is working fine
on the same machine if run under using visual studio.net (both
debug mode & release mode), I have remove & reinstall VS 2004, it is still
the same.
4) I put some trace in the generated method, looks like the error happened
when the method was called, but has not execute anything on the method yet
(the was
not trace out
5) I am using the following code to call the generated method
public delegate void SetValue( DataRow rw, Object objrtn);
public SetValue delemethod=null ;

private static void ExecSetValue(Ar rayList arr, Object objrtn,CTask
objtask,DataRow rw,string task_id)
{
if (objtask.deleme thod==null)
objtask.delemet hod=BuildStatic DelegateMethod( arr,objrtn,task _id);

if (objtask.deleme thod==null)
Trace.WriteLine ("delemethod is NULLLLLLLLLLLL" ,"ERROR");
objtask.delemet hod(rw,objrtn);
}

}

6) I am using the following code to emit the IL code
static public SetSQLParam BuildStaticDele gateSQL(ArrayLi st objlstsp,Object
O,string task_id)
{

string strClassName="S QLExecSetSQL" + task_id;
TypeBuilder myTypeBuilder = myModule.Define Type(strClassNa me,
TypeAttributes. Public);

string strMethodName=" SetValue" +task_id;

MethodBuilder ParMethod = myTypeBuilder.D efineMethod(str MethodName,
MethodAttribute s.Public | MethodAttribute s.Static , typeof(void),
new Type[] { typeof(Session) ,
typeof(Object),
typeof(SqlParam eter[]),
typeof(CTask),
typeof(String)} );

Label[] arrLoadValueStr ing=new Label[objlstsp.Count];
Label[] arrSetValue=new Label[objlstsp.Count];
ILGenerator ILParaFunc= ParMethod.GetIL Generator(); // Create local
variables.
MethodInfo targetTrace = typeof(Trace).G etMethod("Write Line", new Type[]
{typeof(String) } );

MethodInfo Methodgetitem = typeof(ArrayLis t).GetMethod("g et_Item", new
Type[] {typeof(int)} );
MethodInfo MethodStringEq = typeof(String). GetMethod("op_E quality", new
Type[] {typeof(String) ,typeof(String) } );
MethodInfo MethodSetSPValu e = typeof(SqlParam eter).GetMethod ("set_Value" ,
new Type[] {typeof(Object) } );
MethodInfo MethodXMLList = typeof(SQLExec) .GetMethod("Get XMLInput", new
Type[]
{typeof(CTask), typeof(String), typeof(Object)} );
Type objType=typeof( Object);
if (O!=null)
objType=O.GetTy pe();

FieldInfo fieldmap=objTyp e.GetField("map field_name");
FieldInfo fieldstruct=obj Type.GetField(" structurename") ;
for (int i=0;i<objlstsp. Count;i++)
{
arrLoadValueStr ing[i]=ILParaFunc.Def ineLabel();
arrSetValue[i]=ILParaFunc.Def ineLabel();

CSqlParameter objsp=(CSqlPara meter)objlstsp[i];
FieldInfo fieldvar;

ILParaFunc.Emit (OpCodes.Ldarg_ 2);
ILParaFunc.Emit (OpCodes.Ldc_I4 ,i);
ILParaFunc.Emit (OpCodes.Ldelem _Ref);
if (objsp.mapfield _name=="XMLLIST ")
{

ILParaFunc.Emit (OpCodes.Ldarg, 4);
ILParaFunc.Emit (OpCodes.Ldarg_ 1);
ILParaFunc.Emit (OpCodes.Call, MethodXMLList );
ILParaFunc.Emit (OpCodes.Callvi rt,MethodSetSPV alue);
continue;

}
if (objsp.structur ename=="Session ")
{
fieldvar=typeof (Session).GetFi eld(objsp.mapfi eld_name);
ILParaFunc.Emit (OpCodes.Ldarg_ 0);
}
else
{
fieldvar=objTyp e.GetField(objs p.mapfield_name );
ILParaFunc.Emit (OpCodes.Ldarg_ 1);
}
ILParaFunc.Emit (OpCodes.Ldfld, fieldvar);
LocalBuilder objvalue= ILParaFunc.Decl areLocal(fieldv ar.FieldType);
ILParaFunc.Emit (OpCodes.Stloc, objvalue);
ILParaFunc.Emit (OpCodes.Ldloc, objvalue);
if (fieldvar.Field Type.BaseType== typeof(System.V alueType) )
{
ILParaFunc.Emit (OpCodes.Box,fi eldvar.FieldTyp e);
}
else
{
ILParaFunc.Emit (OpCodes.Brtrue ,arrLoadValueSt ring[i]);
ILParaFunc.Emit (OpCodes.Ldstr, "");

ILParaFunc.Emit (OpCodes.Br,arr SetValue[i]);
ILParaFunc.Mark Label(arrLoadVa lueString[i]);

ILParaFunc.Emit (OpCodes.Ldloc, objvalue);
}
ILParaFunc.Mark Label(arrSetVal ue[i]);
ILParaFunc.Emit (OpCodes.Callvi rt,MethodSetSPV alue);

dear all, I am using the GetTypes method of an assembly object in order to check that it implement a particular needed interface for my application. system.Reflexion.Assembly.LoadFrom(sFile).GetTypes was working fine until today where I get an error saying that all type in assembly cannot be loaded.

I'm creating a dynamic assembly which has one type with one constructor, the type inherits a base class Season, which is in the current assembly. I am trying to emit a constructor which simply calls the base constructor with the 4 args passed in, but I get this error Message at the second last line of the method CreateSeason (Marked with <<<<<) An unhandled exception of type 'System.MissingMethodException' occurred in mscorlib.dll ...

Is there a way to use the Reflection.Emit namespace classes to load an existing assembly, then modify it by emitting IL to the loaded assembly, then saving the modified assembly back to a file? Thanks, John

Hi there, I'm currently trying to call some API-Functions via Reflection.Emit since I need to bind to different dlls based on user input. The dynamic creation of the required PInvoke-Methods works just fine and when invoked the functions are executed perfectly well. The only problem is that I seem to be unable to get back any return values. To simplify the whole case I created a test-setup that binds to user32.dll, dynamically creates a...

I have put some code together that creates an enum dynamically from some database values. The enum can be read perfectly by an application that references the dynamically generated dll. If I /emit/ a new version of the assembly, and start the application again, the new values will appear for the enum. However, suppose I want the application to remain in a running state.

This is the simplified code I'm trying to generate: ilg.DeclareLocal(typeof(int)); // define local integer Label exit = ilg.DefineLabel(); // define "exit" label ilg.Emit(OpCodes.Ldc_I4_0); // put 0 on the stack ilg.Emit(OpCodes.Stloc_0); // set the local integer to 0 ilg.Emit(OpCodes.Ldloc_0); // load the local integer (0) on the stack ilg.Emit(OpCodes.Ldc_I4_1); // load integer 1 on the stack

I am new to creating dynamic methods and I find that I have need to do so. I have read through some IL and emit examples and have gotten some simple programs to work. However, I cannot seem to use the opcode Call correctly. This example gives me an "CLR detectd and invalid program" exception at the line handler.invoke. I am sure the error is a simple one. Could someone help me? public partial class ILTest : System.Web.UI.Page {...

Hi, I am working in C# with an Object / Relational Database mapping framework, where I want to generate method calls based on string representation of the call signature. I have used reflection and Method-/Field-/PropertyInfo invokation to do this, but now I want to make the calls faster by using Emit and DynamicMethods I am now trying to create a factory method that creates a dynamic method as a "wrapper" around a method call with no...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
