如何通过c#以编程方式运行多个SSIS包

家伙，我使用这个代码片段，我执行多个SSIS包，当第一个完成时，执行另一个需要很长时间，但是我在CMD上运行脚本命令行，它执行得很快。所以我认为这是代码的问题，你知道为什么吗?下面是我的代码:

SSISHelper.ExecuteSSISPackage("/F '"C:''Users''v-nashi''Documents''visual studio 2010''projects''ImportExcel''ImportExcel''LYO_DailyLogin.dtsx'"");
SSISHelper.ExecuteSSISPackage("/F '"C:''Users''v-nashi''Documents''visual studio 2010''projects''ImportExcel''ImportExcel''LYO_COSMOS_Activities.dtsx'"");

    /// <summary>
    /// Excuete SQL Server Integration Services packages with parameter.
    /// </summary>
    /// <param name="para">parameter</param>
    /// <returns>bool</returns>
    public static bool ExecutePackage(string parameter)
    {
        if (File.Exists(DTExec_Path) == false)
            throw new Exception("The file DTExec.exe is not found, or the file is not exist.");
        Process process = new Process();
        process.StartInfo.FileName = DTExec_Path;
        process.StartInfo.Arguments = parameter;
        // True if the shell should be used when starting the process; false if the process should be created directly
        // from the executable file.
        process.StartInfo.UseShellExecute = true;
        process.StartInfo.RedirectStandardOutput = true;
        process.StartInfo.RedirectStandardError = true;
        Console.WriteLine("{0} {1}", DTExec_Path, parameter);
        process.Start();
        process.WaitForExit();
        string[] results = process.StandardOutput.ReadToEnd().Split(''n');
        foreach (string item in results)
        {
            if (item.Contains("DTExec: The package execution returned DTSER_SUCCESS (0)."))
                return true;
        }
        return false;
    }

我只是想以编程方式运行SSIS包，还是更好的方式?

Microsoft.SqlServer.Dts.Runtime.Application app = new Microsoft.SqlServer.Dts.Runtime.Application();
            string packagePath = "Path of your SSIS package";
            Package package = app.LoadPackage(packagePath, null);
            //Assign your variables here.
            Variables vars = package.Variables;
            vars["FileName"].Value = variables.FileName;

            Microsoft.SqlServer.Dts.Runtime.DTSExecResult results = package.Execute();
            if (results == DTSExecResult.Success)
            {
               //Do what u want after success.
            }
