Server Error in '/Ajax' Application.

The resource cannot be found.

Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is spelled correctly. 

Requested URL: /Ajax/~/OLE+Automation+English.pdf

Version Information: Microsoft .NET Framework Version:2.0.50727.1433; ASP.NET Version:2.0.50727.1433

我该怎么办？

what can i do ??

推荐答案

/Ajax/~/OLE+Automation+English.pdf

您可以亲眼看到预期的路径看起来不正确。 （它在路径字符串之间有tilda）



这是一个相对路径问题。有一种方法可以处理URL'。阅读： ResolveUrl [ ^ ]。



我建议您在设置控件/图像源之前使用此提示并正确解析路径：解决多文件夹网站中的路径 [ ^ ]



做这样的事情也有帮助： ResolveUrl（路径）;

/Ajax/~/OLE+Automation+English.pdf
You can see for yourself that the path expected does not look like correctly formed. (It has tilda in between a path string)

It is a relative path issue. There is a method exposed to handle URL''s. Have a read: ResolveUrl[^].

I would suggest you to use this Tip and resolve the path correctly before setting the control/image source: Resolving Paths in a Multi-Folder WebSite[^]

Doing something like this can also help: ResolveUrl(path);
