c# - 错误 CS0234 : The type or namespace name 'CustomMarshalers' does not exist in the namespace 'System.Runtime.InteropServices'

Question

using System;    
using System.Collections; 
using System.Reflection; 
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;
using System.Runtime.InteropServices.CustomMarshalers;

namespace mshtml
{
    [DefaultMember("item"), CompilerGenerated, Guid("3050F21F-98B5-11CF-BB82-00AA00BDCE0B"), TypeIdentifier]
    [ComImport]
    public interface IHTMLElementCollection : IEnumerable
    {
        void _VtblGap1_3();
        [DispId(-4)]
        [return: MarshalAs(UnmanagedType.CustomMarshaler, MarshalTypeRef = typeof(EnumeratorToEnumVariantMarshaler))]
        IEnumerator GetEnumerator();
    }
}

上面的代码给我以下错误:

Error CS0234: The type or namespace name 'CustomMarshalers' does not exist in the namespace 'System.Runtime.InteropServices' (are you missing an assembly reference?)

请教如何解决？这是一个反编译代码，我是 C# 的初学者。

你必须包含 CustomMarshalers.dll
示例:
使用项目添加引用 -> 添加引用 -> 浏览 -> 转到位置 "C:\Windows\assembly\GAC_32\CustomMarshalers\2.0.0.0__b03f5f7f11d50a3a" -> 选择 CustomMarshalers.dll
