推荐答案
在此处阅读有关内容(
Reading about this here (http://codebetter.com/petervanooijen/2007/06/18/including-a-winforms-user-control-in-an-asp-net-web-page/[^] )
check out the following...
Use Internet Explorer. This does not work in any of the other browsers.
Have the .NET framework installed on the client machine.
The site should be included in the trusted sites list of the browser.
The browser should be allowed to download files from the (trusted) site.
There are many caveats for the client when you try this, so I would suggest reading a few articles and tutorials about this topic to gain a better understanding of what is allowed.
