Methods with params keyword omit the keyword on C# export about ilspy HOT 4 CLOSED

Can you please share the binary? The modifier might be missing in the metadata.

We have test cases that cover this, so diagnosing this will require the binary. If you do not want to share the binary, you could simply provide the IL code of the class.

If you look at the IL code in ILSpy look for this attribute:

       .param [1]
            .custom instance void [System.Runtime]System.ParamArrayAttribute::.ctor() = (
                01 00 00 00
            )

If it's not there, the attribute is missing in metadata and ILSpy is correct and works as expected.

I can't share the binary. It's part of a commercially released game.

Where in ILSpy would I look for that text? And if the field you are looking for isn't there, what might cause it to be missing? I see the text you mention in other methods that use the params keyword.

This is the IL with C# view of the method:

.method public hidebysig newslot virtual 
	instance object Call (
		object[] args
	) cil managed 
{
	// Method begins at RVA 0x3e10d
	// Header size: 1
	// Code size: 2 (0x2)
	.maxstack 8

	// return null;
	IL_0000: ldnull
	IL_0001: ret
} // end of method Mod::Call

from ilspy.

The parameter attribute should be right above the // Method begins at comment.

So ILSpy is displaying exactly what is there in the binary. This is not a bug, it's working as intended.

Thanks. I'll be pointing the devs to this post.
