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

class Class1
{
public static void Main()
{
System.Reflection.Assembly SampleAssembly;
SampleAssembly =
System.Reflection.Assembly.LoadFrom("C:\\SimpleSol utions\\asmload\\asmtoload
\\bin\\Debug\\asmtoload.dll");
System.Type[] Types = SampleAssembly.GetTypes();
foreach (System.Type oType in Types)
{
System.Console.WriteLine(oType.Name.ToString());
string strName = oType.Name.ToString();
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.Threading.Thread.Sleep(5000);
}

}
}

Almost there,

try;
System.Object pObj = System.Activator.CreateInstance(oType);
System.Reflection.MethodInfo[] vMethods =
oType.GetMethods(BindingFlags.Public | BindingFlags.Instance);
for(int vIdx=0; vIdx< vMethods.Length; vIdx++)
{
string vName = vMethods[vIdx].Name;
System.Console.WriteLine("Invoke method " + vName + " with 2 string
arguements");
object[] vArgs = new object[2];
vArgs[0] = "My string arguement #1";
vArgs[1] = "My string arguement #2";
oType.InvokeMember(vName, BindingFlags.InvokeMethod, 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.Reflection.Assembly SampleAssembly;
SampleAssembly =
System.Reflection.Assembly.LoadFrom("C:\\SimpleSol utions\\asmload\\asm
toload
\\bin\\Debug\\asmtoload.dll");
System.Type[] Types = SampleAssembly.GetTypes();
foreach (System.Type oType in Types)
{
System.Console.WriteLine(oType.Name.ToString());
string strName = oType.Name.ToString();
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.Threading.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 assemblyInstance = Assembly.LoadFrom(assembly);
assemblyInstance.GetType(type).InvokeMember(method , BindingFlags.Public |
BindingFlags.InvokeMethod |
BindingFlags.Instance,null,assemblyInstance.Create Instance(type), null);
