how do i access methods when the .net assembly was loaded with late biding?

class Class1
{
public static void Main()
{
System.Reflecti on.Assembly SampleAssembly;
SampleAssembly =
System.Reflecti on.Assembly.Loa dFrom("C:\\Simp leSolutions\\as mload\\asmtoloa d
\\bin\\Debug\\a smtoload.dll");
System.Type[] Types = SampleAssembly. GetTypes();
foreach (System.Type oType in Types)
{
System.Console. WriteLine(oType .Name.ToString( ));
string strName = oType.Name.ToSt ring();
System.Object pObj = SampleAssembly. CreateInstance( "asmtoload" + "." +
strName);
//System.Console. WriteLine(pObj. IOCTL("foo")); THIS IS A BUILD ERROR
BECAUSE IOCTL method is not accessible, how to access method if type info of
dynamicaly loaded dll?
System.Threadin g.Thread.Sleep( 5000);
}

}
}

Almost there,

try;
System.Object pObj = System.Activato r.CreateInstanc e(oType);
System.Reflecti on.MethodInfo[] vMethods =
oType.GetMethod s(BindingFlags. Public | BindingFlags.In stance);
for(int vIdx=0; vIdx< vMethods.Length ; vIdx++)
{
string vName = vMethods[vIdx].Name;
System.Console. WriteLine("Invo ke method " + vName + " with 2 string
arguements");
object[] vArgs = new object[2];
vArgs[0] = "My string arguement #1";
vArgs[1] = "My string arguement #2";
oType.InvokeMem ber(vName, BindingFlags.In vokeMethod, null, pObj, vArgs);
}

You will get some errors if you run this "as is", due to the fact that all
the methods will not take 2 string arguements - but this should get you
heading in the right direction (for all you cross posts!)

Hello Daniel,

Your best bet for late binding is to use VB .NET. It's way too much work
to program late binding code in C# using Reflection...

how do i access methods when the .net assembly was loaded with late
biding?

class Class1
{
public static void Main()
{
System.Reflecti on.Assembly SampleAssembly;
SampleAssembly =
System.Reflecti on.Assembly.Loa dFrom("C:\\Simp leSolutions\\as mload\\asm
toload
\\bin\\Debug\\a smtoload.dll");
System.Type[] Types = SampleAssembly. GetTypes();
foreach (System.Type oType in Types)
{
System.Console. WriteLine(oType .Name.ToString( ));
string strName = oType.Name.ToSt ring();
System.Object pObj = SampleAssembly. CreateInstance( "asmtoload" +
"." +
strName);
//System.Console. WriteLine(pObj. IOCTL("foo")); THIS IS A BUILD
ERROR

System.Threadin g.Thread.Sleep( 5000);
}
}
}

try out this code:
It loads a form from a dll calling the show method.
I post it in another thread as well.

string assembly = "ClassLibrary1. dll";
string method = "Show";
string type = "Form1";
Assembly assemblyInstanc e = Assembly.LoadFr om(assembly);
assemblyInstanc e.GetType(type) .InvokeMember(m ethod, BindingFlags.Pu blic |
BindingFlags.In vokeMethod |
BindingFlags.In stance,null,ass emblyInstance.C reateInstance(t ype), null);
