使用 Visual C# 2010 Express 在 C# 项目中添加引用“SHDocVw" [英] Add reference 'SHDocVw' in C# project using Visual C# 2010 Express

问题描述

我正在学习使用 MS Visual Studio 2010 和 C# 创建 BHO 的教程.为了运行教程代码，我必须在我的项目中添加这个引用:-

I am following a tutorial which creates a BHO using MS Visual Studio 2010 and C#. In order to run the tutorial code, I have to add this reference in my project:-

使用 SHDocVw

using SHDocVw

但它在添加引用的 .NET 或 COM 部分中不可用.

But it is not available in .NET or COM section in Add References.

所以我想问一下这个命名空间在 Microsoft Visual C# 2010 Express 中不可用吗?如果可用，如何添加它.

So I wanted to ask is this namespace not available in Microsoft Visual C# 2010 Express? and if it is available, how to add it.

这是我的中途项目代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace IEPlugin
{
 [
    ComVisible(true),
    InterfaceType(ComInterfaceType.InterfaceIsIUnknown),
    Guid("FC4801A3-2BA9-11CF-A229-00AA003D7352")
]
public interface IObjectWithSite
{
    [PreserveSig]
    int SetSite([MarshalAs(UnmanagedType.IUnknown)]object site);
    [PreserveSig]
    int GetSite(ref Guid guid, out IntPtr ppvSite);
}
[
    ComVisible(true),
    Guid("2159CB25-EF9A-54C1-B43C-E30D1A4A8277"),
    ClassInterface(ClassInterfaceType.None)
]

public class BHO : IObjectWithSite
{
    private WebBrowser webBrowser;

    public int SetSite(object site)
    {
        if (site != null)
        {
            webBrowser = (WebBrowser)site;
            webBrowser.DocumentComplete +=
              new DWebBrowserEvents2_DocumentCompleteEventHandler(
              this.OnDocumentComplete);
        }
        else
        {
            webBrowser.DocumentComplete -=
              new DWebBrowserEvents2_DocumentCompleteEventHandler(
              this.OnDocumentComplete);
            webBrowser = null;
        }

        return 0;

    }

    public int GetSite(ref Guid guid, out IntPtr ppvSite)
    {
        IntPtr punk = Marshal.GetIUnknownForObject(webBrowser);
        int hr = Marshal.QueryInterface(punk, ref guid, out ppvSite);
        Marshal.Release(punk);
        return hr;
    }

    public void OnDocumentComplete(object pDisp, ref object URL)
    {
        HTMLDocument document = (HTMLDocument)webBrowser.Document;
    }

}

}

这是附加的错误:-

错误 1 ​​找不到类型或命名空间名称SHDocVw"(您是否缺少 using 指令或程序集引用?)

Error 1 The type or namespace name 'SHDocVw' could not be found (are you missing a using directive or an assembly reference?)

错误 2 找不到类型或命名空间名称WebBrowser"(您是否缺少 using 指令或程序集引用?)

Error 2 The type or namespace name 'WebBrowser' could not be found (are you missing a using directive or an assembly reference?)

推荐答案

您需要添加对名为 Microsoft Internet Controls 的 COM 组件的引用.

You need to add a reference to a COM component called Microsoft Internet Controls.
