ASP. NET uses the FileUpload control to upload pictures and rename

I created a images image folder in the root directory, the uploaded images are here

Paste the following code

if(fileupload1.hasfile) {stringfilename =Fileupload1.filename;//Get upload namestringFileext =System.IO.Path.GetExtension (filename);//returns the suffix of the specified picturestringFilenamaes = DateTime.Now.ToString ("YYYYMMDDHHFFSS") +Fileext;//Get current TimeFileupload1.saveas (Server.MapPath (".") +"//images//"+Filenamaes);//upload the Images folder to this project's root directory This. Fileup_text. Text ="Upload success!";}Else{ This. Fileup_text. Text ="you haven't chosen a file yet!";}
