Asp.net
通過文件上傳控制項上傳文件時在c#.net中重命名文件並將文件的更改名稱保存在數據庫中
我有文件上傳器，通過它我瀏覽文件並在字元串變數中儲存瀏覽文件的名稱。現在我想用儲存在另一個字元串變數中的另一個名稱重命名這個上傳文件名
string strRoleValue = ddlrole.SelectedValue; string strfilename = FileUpload1.FileName; string existpath = Server.MapPath("~\\JD\\"); DirectoryInfo ObjSearchFile = new DirectoryInfo(existpath); string saveLocation = existpath + strfilename; FileUpload1.SaveAs(saveLocation);strRoleValue 這個變數包含我想用來重命名通過 fileupload 上傳的文件的名稱。通過fileupload控制項上傳的文件名儲存在
strfilename. 所以在將此文件保存到指定文件夾之前，我想用 strRoleValue 值重命名它。我怎樣才能做到這一點..plz幫助
