并在字符串变量中输出浏览文件的名称.
现在我想用另一个存储在另一个字符串变量中的名称重命名这个uplaod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此变量包含我想用来重命名通过fileupload上传的文件的名称.
通过存储在strfilename中的fileupload控件上传的文件名.
所以在将此文件保存到指定文件夹之前
我想用strRoleValue值重命名它.
我怎样才能实现这个… plz的帮助
