如何动态地将物理路径转换为虚拟路径?

问题描述

到目前为止，这是我尝试过的工作，我将给定路径转换为虚拟路径，但是当我的网站不在同一文件夹中时，它将创建错误，因此我希望将转换为物理路径的代码转换为像这样的虚拟路径

物理路径:: C:\ Users \ NET DEVELOPMENT \ Desktop \ AgentWeb

我希望它能转换成这样的虚拟路径
虚拟路径::〜/AgentImages/

这里的代理图片是我的agentweb邮件文件夹中的一个文件夹，代码是这样的

This is what i have tried so far i am converting given path to virtual path but when my website is not in the same folder it will create error so i want a code that converts what ever the physical path is will be converted to virtual path like this

physical path:: C:\Users\NET DEVELOPMENT\Desktop\AgentWeb

and i want it to get converted to virtual path like this
virtual path:: ~/AgentImages/

here agent images is a folder in my agentweb mail folder and the code is like this

protected void btnSubmit_Click(object sender, EventArgs e)
   {
       int id = Convert.ToInt32(Session["AgentMasterID"]);
       string temp = "";
       if (fuProducImage.HasFile)
       {
           if (CheckFileType() == true)
           {

               string directoryPath = Server.MapPath("~/AgentImages/") + id;
               string vitualp = directoryPath.Replace(@"C:\Users\NET DEVELOPMENT\Desktop\AgentWeb", "~").Replace(@"\", "/");
               string filepath = directoryPath + "/" ;
               if (!Directory.Exists(MapPath(filepath)))
               {

                   Directory.CreateDirectory(MapPath(directoryPath + "/"));
                  fuProducImage.SaveAs(MapPath(filepath+fuProducImage.FileName));
                  temp = directoryPath + fuProducImage.FileName;
               }
               else
               {

                   fuProducImage.SaveAs(MapPath(filepath + fuProducImage.FileName));
                   temp = filepath + fuProducImage.FileName;
               }

               //fuProducImage.SaveAs(MapPath("~/AgentImages/" + fuProducImage.FileName));


               lblPimage.Visible = true;
               lblPimage.Text = "Image Uploaded Sucesfully";
           }
       }

推荐答案

public string ReverseMapPath( string Path )
{
    string szRoot = Server.MapPath ( "~" );

    if ( Path.StartsWith ( szRoot ) )
    {
        return("~/" + Path.Replace ( szRoot, string.Empty ).Replace ( @"\", "/" ));
    }
}

protected void btnSubmit_Click(object sender, EventArgs e)
{
    int id = Convert.ToInt32(Session["AgentMasterID"]);
    string temp = "";
    if (fuProducImage.HasFile)
    {
        if (CheckFileType() == true)
        {
            string directoryPath = Server.MapPath("~/AgentImages/") + id;
            if (!Directory.Exists(directoryPath))
            {
                Directory.CreateDirectory(directoryPath);
            }

            temp = Path.Combine(directoryPath, fuProducImage.FileName);
            fuProducImage.SaveAs(temp);

            lblPimage.Visible = true;
            lblPimage.Text = "Image Uploaded Sucesfully";
        }
    }
}

public static string MapPathReverse(string fullServerPath)
    {
        return @"~\" + fullServerPath.Replace(HttpContext.Current.Request.PhysicalApplicationPath,String.Empty);
    }
