Hello,

Is there a way to expose to COM a method of a C# type according to the
following IDL:

[vararg] void MyMethod([in, out] SAFEARRAY(VARIANT)* params)

Hi

Here is a sample for your reference.
[ClassInterface(ClassInterfaceType.AutoDual)]
public class TestClass
{
public void
MyMethod([MarshalAs(UnmanagedType.SafeArray,SafeArraySubType =VarEnum.VT_VARI
ANT)]ref System.Array param)
{
;
}
}

Also here is link about Default Marshaling for Arrays in .NET.

Hi Peter,

If you look at the resulting IDL more carefully, you'll see your method is
exposed without the vararg attribute, which was the main point. Well, I
managed to get what I want automatically by creating a NAnt task for editing
IDL. Thanks for your help.
