As an 'academic' exercise, I've attempted to create a COM interop assembly
using classes from the Reflection.Emit namespace. The problem that I ran
into was in specifying the
SizeParamIndex for an LPArray.
The generated IL should look something like:
.method public hidebysig newslot abstract virtual
instance void SetArray([in] int32 count,
[in] int32[] marshal([+0]) 'array') runtime managed internalcall
but instead, the 2nd parameter looks like (note the missing index argument):
[in] int32[] marshal([]) 'array') runtime managed internalcall
with an equivalent C# definition of:
void SetArray( int count, [MarshalAs(UnmanagedType.LPArray,
SizeParamIndex=0)] int[] array);
I've attached the simplest C# source file that will demonstrate the Emit
code (as far as I can take it). Any ideas on how to specify the array size
parameter index for the marshal keyword?
