等一下？你希望在ASP.NET中使用 System.Windows.Forms 吗？如果是这样，就算了！;可能你不知道ASP.NET是如何工作的。



ASP.NET对客户端安装的软件没有任何假设。它通常使用Javascript，CSS和其他可通过通用Web浏览器读取的资源生成纯HTML。没有东西可以托管您的表格。所有.NET代码仅在服务器端托管;但是，如果你非常正式地在服务器端托管表单，谁会看到它们？你有提示吗？如果没有，请开始阅读ASP.NET的功能，但从HTTP服务器和客户端背后的基本思想开始。请参见 http://www.asp.net/get-started [ ^ ]。

Wait a minute? Are you hoping to use System.Windows.Forms in ASP.NET? If so, just forget it; probably you have no idea how ASP.NET works.

ASP.NET makes no assumption on the software installed in client. It normally generate plain HTML with Javascript, CSS and other resources readable with a general-purpose Web browser. There is nothing to host your Forms. All .NET code is hosted only on server side; but if you, quite formally, host the Forms on server-side, who will see them? Did you get the hint? If not, start reading about what ASP.NET does, but start from the very basic ideas behind HTTP servers and clients. See http://www.asp.net/get-started[^].

1.创建这种类型的新项目，首先必须选择一种.NET语言 - 无论是C＃，VB.NET还是C ++ / CLI都无关紧要。

2.然后，选择Windows类别缩小列出的项目类型的范围。

3.最后，选择名为Windows Forms Control Library的项目类型。

1.To create a new project of this type, you first have to pick one of the .NET languages—it doesn't matter which—either C#, VB.NET or C++/CLI.
2.Then, select the "Windows" category to narrow down the scope of the project types that are listed.
3.Finally, select the project type called "Windows Forms Control Library".
