Getting the helpstring attribute applied to C# properties exposed via COM interfaces
I'm currently working on a library that's to be exposed to COM for use in a legacy project that's being upgraded. I'm creating interfaces that are to be exposed, and they have properties on them with long, int, etc types. Using the DescriptionAttribute, I can get helpstrings generated in the .tlb for interfaces, classes, and methods, but for some reason it doesn't seem to want to work for prope开发者_运维问答rties. Is there anyway to get a helpstring generated in the TLB output for properties ?
You have to put the attribute on the getter and setter individually. Like this:
using System;
using System.ComponentModel;
using System.Runtime.InteropServices;
namespace ClassLibrary1 {
[ComVisible(true), InterfaceType(ComInterfaceType.InterfaceIsDual)]
public interface IFoo {
int property {
[Description("prop")]
get;
[Description("prop")]
set;
}
}
}
Repeating the description is clumsy, but also required in IDL.
