How to call a method written in VB.NET with C # with optional arguments

Question

I have a method written in VB.NET. It looks like this:

Shared Sub SomeMethod(ByVal Id As Guid, 
                      Optional ByVal str1 As String = "foo", 
                      Optional ByVal str2 As String = "")

I want to call this method from C # 3.0, and I want it to use its default arguments. I tried to skip System.Reflection.Missing.Value, but I cannot use it as a String.

Is there any way to do this?

Thanks in advance for your help.
