Ok, Pradeep. Actually you missed his initial threads.

He was talking about System Temp folders, now explained correctly with project folder.

Sagar,

I given a reply to your other thread, try at your end.

Suthish,

I understood what your are saying. But what I was trying to explain is talking about system temporary folder is irrelevant to this thread, as @Sagar is using System.Web.Hosting.HostingEnvironment.MapPath which maps application virtual path with physical path. It doesn't map virtual path with system temporary folder. It is just he has "temp" folder in his application root directory.

Anyway as @Sagar has found solution no more discussion is needed.

Pradeep, We talking about system Temporary folders. "temp" keyword and Temporary folders path is different in different OS.

The Server.MapPath returns application root directory, when you are passing folder name to this method, it will try to map the folder name with root directory. So if somebudy is passing "~/temp/" to Server.MapPath it means they are trying to get local full path. The OS does not comes into the picture.

Why using like this "MapPath("~/temp/". I think this part will be different on different OS. Do a good testing before deploying/publishing it.

Finaly i solved my problem

protected void Session_End(object sender, EventArgs e) {
string userId = Session["UserId"].ToString();
string path;
string ImagePath =Session["Imagepath"].ToString();

path = System.Web.Hosting.HostingEnvironment.MapPath("~/temp/" + userId + "_" + ImagePath);

FileInfo filepath = new FileInfo(path);

if (filepath.Exists) {

File.Delete(filepath.FullName);

Session.Abandon();

}

}
