asp.net - Is my path virtual?

问题

Is there a built-in asp.net method for checking the "virtualness" of a path?

The only way I've been able to do it so far is with the following try block:

public void Foo(String path){

    try
    {
        path = Server.MapPath(path);
    }
    catch(HttpException){}

    // do stuff with path
}

回答1:

Would the Path.IsPathRooted method work?

You're resulting code would be:

public void Foo(String path)
{
    if(!Path.IsPathRooted(path))
    {
        path = Server.MapPath(path);
    }

    // do stuff with path
}
