在 vbscript 中调用 C# dll [英] Calling C# dll in vbscript

问题描述

我正在尝试从 QTP 调用 C# dll(使用 vbscript).我尝试了很多方法都没有成功:

I am trying to call a C# dll from QTP (uses vbscript). I have tried a number of things with no success:

• Visual Studio 2010
• 创建 C# 类库 (st.dll)

代码:

using System;
using System.Collections.Generic;
using System.Text;   

namespace st
{
    public class Class1
    {
        public static int GetValue()
        {
            return 34;
        }
    }
}

• regasm/codebase st.dll
  • 失败，因为它不是有效的 .NET 程序集"

  在 QTP/vbscript 中，我尝试过

  In QTP/vbscript, I have tried

  • extern.Declare micInteger, "GetValue", "e:st.dll", "GetValue"
    • 返回消息:过程调用或参数无效"

    无论 QTP，我将不胜感激任何有关如何从 .vbs 文件调用 c# dll 的见解.

    Regardless of QTP, I would greatly appreciate any insight on how to call the c# dll from a .vbs file.

    推荐答案

    我能够通过执行以下操作来使其正常工作:

    I was able to get this working by doing the following:

    在 VS 2010 中创建一个新的 C# dll.

    Create a new C# dll in VS 2010.

    namespace st4
    {
        public class st4_functions
        {
            public int GetValue()
            {
                return 34;
            }
        }
    }
    

    在 QTP 中，我添加了以下几行:

    In QTP I added the following lines:

    Set obj = DotNetFactory.CreateInstance("st4.st4_functions", "c:\st4.dll")
    MsgBox obj.GetValue()
    

    感谢所有回答我问题的人.虽然我没有做 COM 解决方案，但它让我想到我可以继续使用 .NET 并导致了这个解决方案.干得好！

    Thanks to all that responded to my problem. Though I did not do the COM solution, it got me thinking that I could stay with .NET and led to this solution. Good job all!

    我创建了一篇博文来详细说明步骤并提供其他信息:
