Answer 1

可能程序没执行成功把System.Windows.Forms.MessageBox.Show("BHO TESTING.2..");放到ourKey.Close();后面看看

Answer 2

我重新改了下弹出框,加多了输出,然后,测试的时候,是输出下面结果:弹出框 2,6,8,10,11,12,13 这几个弹出框都弹出来,然后, cmd 提示注册成功.C:\Users\Administrator>"C:\Program Files (x86)\Test Program\tools\x86\RegAsm.exe

    }

Answer 3

然后, 可能是因为注册表的键值也没有, 所以, 当我打开 IE 测试 BHO 的时候, 好像根本就没反应, 下面的代码没有在页面加载完成的时候被调用:没有弹出: System.Windows.Forms.MessageBox.Show("BHO TESTING...");
public class BHO : IObjectWithSite
{
    WebBrowser browser;
    HTMLDocument document;    public void OnDocumentComplete(object pDisp, ref object URL)
    {
        System.Windows.Forms.MessageBox.Show("BHO TESTING...");
    }    public int SetSite(object site)
    {
        if (site != null)
        {
            browser = (WebBrowser)site;
            browser.DocumentComplete += new DWebBrowserEvents2_DocumentCompleteEventHandler(this.OnDocumentComplete);
        }
        else
        {
            browser.DocumentComplete -= new DWebBrowserEvents2_DocumentCompleteEventHandler(this.OnDocumentComplete);
            browser = null;
        }
        return 0;
    }    public int GetSite(ref Guid guid, out IntPtr ppvSite)
    {
        IntPtr punk = Marshal.GetIUnknownForObject(browser);
        int hr = Marshal.QueryInterface(punk, ref guid, out ppvSite);
        Marshal.Release(punk);
        return hr;
    }
.....

Answer 4

我重新将上面的 dll 放到 windows server 2003 上面运行, 同样的结果却成功注册与成功在 IE 运行 BHO. 这个问题是与 OS 的版本有关,谢谢.
