dataGridView返回当前行单击行的值
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e) { int rowindex = e.RowIndex; string code_id = dataGridView1.Rows[rowindex].Cells[0].Value.ToString(); }

以管理员身份运行某程序
有一条case需要测试non-admin用户下运行软件产生的event信息。 由于Automation的大job是在admin用户下运行的，因此需要切换到non-admin用户，而这无论是在WTT中还是.NET中切换用户都是比较困难的。因此需要采用run as的策略，也就是在当前的admin用户下，通过code来使得所测软件在non-admin用户下运行。
下面这段代码实现了在指定的用户下运行某程序。可以从config文件中读取指定的用户。
注意：指定用户的密码不能为空，否则会有异常抛出。
public static bool LauchMontanaBrt(string inUserName,string inPassWord) { try { Process MBRTProcess = new Process(); MBRTProcess.StartInfo.UserName = inUserName; string strPWD = inPassWord; SecureString password = new SecureString(); foreach (char c in strPWD.ToCharArray()) { password.AppendChar(c); } MBRTProcess.StartInfo.Password = password; MBRTProcess.StartInfo.WorkingDirectory = AppDomain.CurrentDomain.BaseDirectory; MBRTProcess.StartInfo.FileName = "xxx.exe"; MBRTProcess.StartInfo.Arguments = "/run /wu"; MBRTProcess.StartInfo.UseShellExecute = false; MBRTProcess.Start(); return true; } catch(Exception error) { Console.writeline(error.Message); return false; } }
