如何将粘贴处理程序添加到C#中的IOleWindow

using System.Runtime.InteropServices;

public class MyWindow : IOleWindow
{
    // IOleWindow接口的GUID
    private static readonly Guid IID_IOleWindow = new Guid("00000114-0000-0000-C000-000000000046");

    // 获取窗口句柄的方法
    int IOleWindow.GetWindow(out IntPtr hwnd)
    {
        hwnd = YourWindowHandle; // 替换为你的窗口句柄
        return 0;
    }
}

public class MyWindow : IOleWindow
{
    // ...

    // 注册粘贴处理程序的方法
    public void RegisterPasteHandler()
    {
        // 获取IOleWindow接口的指针
        IntPtr pUnknown = Marshal.GetIUnknownForObject(this);
        IntPtr pOleWindow;
        Marshal.QueryInterface(pUnknown, ref IID_IOleWindow, out pOleWindow);

        // 注册粘贴处理程序
        IDataObject dataObject = Clipboard.GetDataObject();
        if (dataObject != null && dataObject.GetDataPresent(DataFormats.Text))
        {
            string text = (string)dataObject.GetData(DataFormats.Text);
            // 处理粘贴的文本
            // ...
        }

        // 释放资源
        Marshal.Release(pOleWindow);
        Marshal.Release(pUnknown);
    }
}

public class MyWindow : IOleWindow
{
    // ...

    public void SomeMethod()
    {
        // ...

        RegisterPasteHandler();

        // ...
    }
}
