Is-it possible in C# to call a method (non-static) without instantiating its class e.g :
public class MyClass
{
public void MyMethod()
{
Console.WriteLine("method called");
}
}
I've tried this method using the System.Reflection.Emit namespace, I copied the IL of MyMethod() to a dynamic method but got an exception :
FatalExecutionEngineError was detected : The runtime has encountered a fatal error. The address of the error was at 0x5dceccf5, on thread 0x2650. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.
Assembly a = System.Reflection.Assembly.GetExecutingAssembly();
Type t = a.GetType("Tutorial.MyClass");
MethodInfo m = t.GetMethod("MyMethod");
MethodBody mb = m.GetMethodBody();
DynamicMethod dm = new DynamicMethod("MethodAlias", null, Type.EmptyTypes, typeof(Tutorial.MainWindow), true);
DynamicILInfo ilInfo = dm.GetDynamicILInfo();
SignatureHelper sig = SignatureHelper.GetLocalVarSigHelper();
ilInfo.SetLocalSignature(sig.GetSignature());
ilInfo.SetCode(mb.GetILAsByteArray(), mb.MaxStackSize);
try
{
dm.Invoke(this, null);
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
Thank you
public static void MyMethod()that's not non-static. and NO you cannot call a non-static method without creating an instance. – Bala RMyMethodstatic? – Sven
