[英]problem in aspx c# rename file before upload and save to name with database
[英]Rename file in c#.net when its is uploaded through file upload control and save chang name of file in database
我有文件上传器,通过它我浏览文件并在字符串变量中存储浏览文件的名称。 现在我想用存储在另一个字符串变量中的另一个名称重命名这个 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。 通过文件上传控件上传的文件名存储在strfilename
。 所以在将此文件保存在指定文件夹中之前,我想用 strRoleValue 值重命名它。 我怎样才能做到这一点..plz 帮助
