               // 10240 KB means 10MB, You can change the value based on your requirement
               if (FileUpload1.PostedFile.ContentLength > 1024000)
               {
                   Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "Alert", "alert('File is too big.')", true);

                   //then save it to the Folder
                   FileUpload1.SaveAs(Server.MapPath(imgPath));
                   Image1.ImageUrl = "~/images/"+imgName;

推荐答案

使用以下StartUpload（）方法

Use below StartUpload() Method

private void StartUpLoad()
       {
           //get the file name of the posted image
              string username = (string)(Session["UserAuthentication"]);

           //get the size in bytes that

           int imgSize = FileUpload1.PostedFile.ContentLength;

           //validates the posted file before saving
           if (FileUpload1.PostedFile != null && FileUpload1.PostedFile.FileName != "")
           {
               // 10240 KB means 10MB, You can change the value based on your requirement
               if (FileUpload1.PostedFile.ContentLength > 1024000)
               {
                   Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "Alert", "alert('File is too big.')", true);

               }
               else
               {
                   //then save it to the Folder
                string[] splitter = FileUpload1.PostedFile.FileName.Split('.');
                string filePath = "Images/" + username +"." + splitter[1].ToString();
                FileUpload1.SaveAs(Server.MapPath(filePath));
                Image1.ImageUrl = "~/" + filePath;
                Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "Alert", "alert('Image saved!')", true);

               }

           }
