后臺(tái)源碼：
protected void BtnUP_Click(object sender, EventArgs e) { if (AttachFile.HasFile) { string FileName = this.AttachFile.FileName;//獲取上傳文件的文件名,包括后綴 string ExtenName = System.IO.Path.GetExtension(FileName);//獲取擴(kuò)展名 string SaveFileName = System.IO.Path.Combine(System.Web.HttpContext.Current.Request.MapPath("UpLoads/"), DateTime.Now.ToLongDateString().ToString() + "-" + FileName);//合并兩個(gè)路徑為上傳到服務(wù)器上的全路徑 AttachFile.MoveTo(SaveFileName, Brettle.Web.NeatUpload.MoveToOptions.Overwrite); string url = "UpLoads/" + DateTime.Now.ToString("yyyyMMddhhmmss") + ExtenName; //文件保存的路徑 float FileSize = (float)System.Math.Round((float)AttachFile.ContentLength / 1024000, 1); //獲取文件大小并保留小數(shù)點(diǎn)后一位,單位是M Response.Write("<script>alert('恭喜您，上傳成功!')</script>"); } else { Response.Write("<script>alert('請(qǐng)選擇文件！')</script>"); } }這里直接獲取上傳文件夾文件名稱提供下載
