Dear Friends,

I have an Item Form Master where i am making an Item and here i have given a functionality of uploading an image for the item on a popup window and save it in a folder with the same name as image name.

Now when i am saving the item then i want to rename the name of the file uploaded but i am not able to rename the same.

The code with which i am trying to save the same is:-

C#

if (!File.Exists(Server.MapPath("~/ItemImage/" + Convert.ToString(Request.QueryString["compid"]) + "/" + Convert.ToString(Request.QueryString["offID"]) + "/" + itemImgName)))
            {
                string newImgName = Convert.ToString(itemID);

                FileUpload file = new FileUpload();

                file.SaveAs(Server.MapPath("~/ItemImage/" + Convert.ToString(Request.QueryString["compid"]) + "/" + Convert.ToString(Request.QueryString["offID"]) + "/" + file.FileName.Replace(itemImgName + "." + fileExt, newImgName + "." + fileExt)));
            }

The above code is executing successfully but the image name doesn't get renamed as per my requirement.

Please let me know where i am going wrong or there is some other option of doing the same.

try by saving new file and deleting the old file..

C#

if (!File.Exists(Server.MapPath("~/ItemImage/" + Convert.ToString(Request.QueryString["compid"]) + "/" + Convert.ToString(Request.QueryString["offID"]) + "/" + itemImgName)))
            {
                string newImgName = Convert.ToString(itemID);
 
                FileUpload file = new FileUpload();
 
                file.SaveAs(Server.MapPath("~/ItemImage/" + Convert.ToString(Request.QueryString["compid"]) + "/" + Convert.ToString(Request.QueryString["offID"]) + "/" + newImgName + "." + fileExt)));

                FileInfo MyFile = new FileInfo(Server.MapPath("~/ItemImage/" + Convert.ToString(Request.QueryString["compid"]) + "/" + Convert.ToString(Request.QueryString["offID"]) + "/" + itemImgName + "." + fileExt));
          
MyFile.Delete();
            }
