        string attachment = string.Empty;
        if (XlsPath.IndexOf("\\") != -1)
        {
            string[] strFileName = XlsPath.Split(new char[] { '\\' });
            attachment = "attachment; filename=" + strFileName[strFileName.Length - 1];
        }
        else

您可以使用下载后手动移动文件

string sourceFile = @"C:\Users\test\Documents\Downloads\test.xls";
string destinationFile = @"D:\emails\test.xls";
// To move a file or folder to a new location:
System.IO.File.Move(sourceFile, destinationFile);
