ASP.NET Server.MapPath: Virtual to Physical Path

The Server.MapPath method in ASP.NET is used to map virtual paths to actual paths in the file system. This method is typically used to obtain file or directory paths within a project.

Here is an example of how to use the Server.MapPath method:

string virtualPath = "~/Images/logo.jpg";
string physicalPath = Server.MapPath(virtualPath);

// 输出物理路径
Console.WriteLine("物理路径：" + physicalPath);

In the example above, we are mapping the virtual path “~/Images/logo.jpg” to the actual path in the physical file system, and storing the result in the variable physicalPath. We then output the physical path to the console.

Please note that the Server.MapPath method can only be used in ASP.NET applications, so it cannot be used in regular C# console applications.
