Question

我在使用Visual Studio 2010，C＃（。Net 4）。

我有一个包含两列DataGridView的应用程序。每列包含我想要运行的程序的参数。

现在我想从我的C＃应用程序运行另一个带有数据网格视图参数的应用程序。另外，我想在运行新进程之前等待3秒。

我尝试了以下代码，但该过程并行运行，而不是一个接一个地运行：

private static Mutex mut = new Mutex();

public void runProgram(string executablePath, string argu1, string argu2)
{
    mut.WaitOne();

    ProcessStartInfo startInfo = new ProcessStartInfo();
    startInfo.WorkingDirectory = Path.GetDirectoryName(executablePath);
    startInfo.FileName = "CMD.exe";
    startInfo.Arguments = "/C " + set.ExecutablePath + " "
                            + argu1 + " " + argu2;

    try
    {
        Process p = Process.Start(startInfo);
        //p.WaitForExit();  // don't start the next process until the first finish -> not good, stuck the app
    }
    catch
    {
        MessageBox.Show("ERROR: unsuccess to run the applicition");
    }

    mut.ReleaseMutex();
}

private void bu_RunProgram_Click(object sender, EventArgs e)
{
    if (!File.Exists(set.ExecutablePath))
    {
        MessageBox.Show("The executable file doesn't exist\nPlease select right executable file in the settings form", "Error");
        return;
    }

    int progRow;
    foreach (DataGridViewRow dgvr in dg_ParametersToRun.Rows)
    {
        progRow = dgvr.Index;
        string argu1 = dg_ParametersToRun.Rows[progRow].Cells[0].FormattedValue.ToString();
        string argu2 = dg_ParametersToRun.Rows[progRow].Cells[1].FormattedValue.ToString();

        Thread threadProgRun= new Thread(() => runProgram(set.ExecutablePath, argu1, argu2));
        threadProgRun.Start();

        Thread.Sleep(3000); // Need to come to this line only when the previous thread finish...
    }
}

说实话，我从未使用线程..

谢谢！

更新代码（根据建议）：

// Aid variable
int paramRowIndex;

public void runNextParameters(object sender, EventArgs e)
{
    paramRowIndex++;
    if (paramRowIndex > dg_RunListTests.Rows.Count) return;   finish run all parameters

            //run the test
    string argu1 = dg_RunListTests.Rows[paramRowIndex].Cells[0].FormattedValue.ToString();
    string argu2 = dg_RunListTests.Rows[paramRowIndex].Cells[1].FormattedValue.ToString();
    runParameters(set.ExecutablePath, componenet, test);
}

public void runParameters(string executablePath, string argu1, string argu2)
{
    ProcessStartInfo startInfo = new ProcessStartInfo();
    startInfo.WorkingDirectory = Path.GetDirectoryName(executablePath);
    startInfo.FileName = "CMD.exe";
    startInfo.Arguments = "/C " + set.ExecutablePath +  " "
                        + argu1 + " " + argu2;
    try
    {
        Process p = Process.Start(startInfo);
        p.Exited += runNextParameters;
    }
    catch
    {
        MessageBox.Show("Unsuccess to run the test again");
    }
}

private void bu_RunParameters_Click(object sender, EventArgs e)
{
    if (!File.Exists(set.ExecutablePath))
    {
        MessageBox.Show("The executable file doesn't exist\nPlease select right     executable file in the settings form", Error);
        return;
    }

    paramRowIndex = 0;
    runNextParameters(sender, e);
}

可能的快速解决方案：启动一个启动两（3）个程序的.bat文件。你必须创建另一个等待3秒钟的程序。
