问题描述
我有文件上传器通过它浏览文件
和strore的名称的浏览文件的字符串变量。
现在我想重命名这个uplaod文件名与另一个名称存储在另一个字符串变量
I have file uploader through which i browse file and strore the name of of browse file in string variable . now i want rename this uplaod file name with another name which stored in another string variable
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此变量包含用于重命名通过fileupload上传的文件的名称。
filename通过fileupload控件存储在 strfilename 中。
