The difference between a virtual path tilde ~ and a slash/

/is the website root directory, ~/is the ASP. Application root directory ... The two are completely different concepts.

The path resolution for "~/" is somewhat special for ASP. It searches the root directory until it matches the directory you specify.

Like what:
Virtual Directory mapping: C:\inetpub\wwwroot\MySite
Then: "/" corresponds to MySite this directory
When you write/1.jpg, then the net will only go to MySite, that is, to find whether mysite/1.jpg exist.
When you write ~/1.jpg, then ASP. NET will look for 1.jpg under the whole MySite, even if
The actual path can also be found in C:\intepub\wwwroot\MySite\images\1.jpg.

In addition, you can use the ~/path representation only for server-side controls.
