问题描述

是否有可能在C#中编写com控件或Activex并在MFC中使用它?

if this possible to write a com control or activex in C# and use it in MFC ?

推荐答案

是.首先，您需要创建COM对象.下面是一个非常简单的示例.

Yes. First, you need to create COM object. Below is a very simple example.

[Guid("123565C4-C5FA-4512-A560-1D47F9FDFA20")]
public interface IDoSomething
{
    [DispId(1)]
    string Name { get; }

    [DispId(2)]
    int DoSomething();
}

[ComVisible(true)]
[Guid("12AC8095-BD27-4de8-A30B-991940666927")]
[ClassInterface(ClassInterfaceType.None)]
public sealed class DoSomething: IDoSomething
{
    public DoSomething()
    {
    }

    public string Name
    {
        get { return ""; }
    }

    public int DoSomething()
    {
        return 4; //random number
    }
}

在那之后，您需要重新组装您的组件. regasm工具将添加必要的注册表COM条目:

After that you need to regasm your assembly. The regasm tool will add the necessary registry COM entries:

regasm.exe /tlb component.dll

/tlb是生成要在MFC应用程序中导入的类型库所必需的.

/tlb is necessary to generate the type library to be imported in your MFC application.

注册程序集后，就可以像其他COM对象一样在MFC应用程序中调用DoSomething.

Once your assembly is registered, you can call DoSomething in your MFC application like any other COM objects.
