Question

我有一个C＃应用程序，它将在任务计划程序中创建重复任务以执行特定程序（根据重复标准发送的触发电子邮件）。

使用C＃我可以在Visual Studio和IIS Express中运行应用程序时成功创建任务。我看到命令窗口弹出，任务成功输入。

但是，当直接通过IIS（通过Web浏览器）进入程序时，我看到任务计划程序没有任何变化，也没有显示任何状态信息的命令窗口。

我试图以管理员身份运行无济于事。根据下面的代码，当一个计划任务不存在时，我需要做哪些修改才能成功添加计划任务，或者修改已经存在的现有重复计划任务，只是改变重复的日期？

这是我到目前为止所做的：

        if (chkActivate.SelectedItem.Text == "Deactivate Reminders")
        {
            chkDaysOfWeek.Enabled = false;
            chkEmailOption.Enabled = false;

            command = "schtasks.exe /Change /TN \"Action Item Reminder\" /Disable";

        }
        else
        {
            chkDaysOfWeek.Enabled = true;
            chkEmailOption.Enabled = true;

            command = "schtasks.exe /Change /TN \"Action Item Reminder\" /Enable";

        }
    List<string> days = new List<string>();

    for (int idx = 0; idx < chkDaysOfWeek.Items.Count; idx++)
    {
        if (chkDaysOfWeek.Items[idx].Selected == true)
        {
            strquery = "UPDATE EmailOption set [Value] = 'true' where [Option] = '" + chkDaysOfWeek.Items[idx].Text.ToString() + "'";
            days.Add(chkDaysOfWeek.Items[idx].Text.Substring(0, 3).ToUpper());
        }
        else
            strquery = "UPDATE EmailOption set [Value] = 'false' where [Option] = '" + chkDaysOfWeek.Items[idx].Text.ToString() + "'";
        SqlCommand cmd = new SqlCommand(strquery, mycon);
        cmd.ExecuteNonQuery();
    }

   // string runascmd = @"schtasks.exe /DELETE /TN ""Action Item Reminder"" /f & schtasks.exe /CREATE /SC WEEKLY /D " + string.Join(",", days) + @" /TN ""Action Item Reminder"" /TR ""C:\ActionAIM_Source\bin\ActionItemReminder.exe"" /ST 00:01 /f & """ + command;
    string runascmd = @"schtasks.exe /CREATE /SC WEEKLY /D " + string.Join(",", days) + @" /TN ""Action Item Reminder"" /TR ""C:\ActionAIM_Source\bin\ActionItemReminder.exe"" /ST 00:01 /f & " + command;

    ProcessStartInfo processInfo = new ProcessStartInfo("cmd.exe");
    processInfo.Arguments = @"runas /env /user:Administrator /K """ + runascmd + @"""";
    //processInfo.Verb = "runas";
    processInfo.UseShellExecute = true;

    try
    {
        Process.Start(processInfo);
    }
    catch (Win32Exception ex)
    {
        Response.Write(ex.ToString());   
    }

修改代码以使用命令ProcessStartInfo（＆＃34; schtasks.exe＆＃34;）而不是ProcessStartInfo（＆＃34; cmd.exe＆＃34;）后，我将命令行字符串拆分为两个命令并将App Pool设置为我的Windows本地帐户，我能够创建任务并修改我通过IIS成功创建的任务。

        if (chkActivate.SelectedItem.Text == "Deactivate Reminders")
        {
            chkDaysOfWeek.Enabled = false;
            chkEmailOption.Enabled = false;

            command = @"/Change /TN ""Action Item Reminder"" /Disable";

        }
        else
        {
            chkDaysOfWeek.Enabled = true;
            chkEmailOption.Enabled = true;

            command = @"/Change /TN ""Action Item Reminder"" /Enable";

        }
        if (chkEmailOption.SelectedItem.Text == "Original")
        {
            strquery = "UPDATE EmailOption set [Value] = 'true' where [Option] = 'Original Due Date'; UPDATE EmailOption set [Value] = 'false' where [Option] = 'ECD'";
            SqlCommand cmd = new SqlCommand(strquery, mycon);
            cmd.ExecuteNonQuery();
        }
        else if (chkEmailOption.SelectedItem.Text == "ECD")
        {
            strquery = "UPDATE EmailOption set [Value] = 'true' where [Option] = 'ECD'; UPDATE EmailOption set [Value] = 'false' where [Option] = 'Original Due Date'";
            SqlCommand cmd = new SqlCommand(strquery, mycon);
            cmd.ExecuteNonQuery();
        }


        List<string> days = new List<string>();

        for (int idx = 0; idx < chkDaysOfWeek.Items.Count; idx++)
        {
            if (chkDaysOfWeek.Items[idx].Selected == true)
            {
                strquery = "UPDATE EmailOption set [Value] = 'true' where [Option] = '" + chkDaysOfWeek.Items[idx].Text.ToString() + "'";
                days.Add(chkDaysOfWeek.Items[idx].Text.Substring(0, 3).ToUpper());
            }
            else
                strquery = "UPDATE EmailOption set [Value] = 'false' where [Option] = '" + chkDaysOfWeek.Items[idx].Text.ToString() + "'";
            SqlCommand cmd = new SqlCommand(strquery, mycon);
            cmd.ExecuteNonQuery();
        }

        string create = @"/CREATE /SC WEEKLY /D " + string.Join(",", days) + @" /TN ""Action Item Reminder"" /TR ""C:\ActionAIM_Source\bin\ActionItemReminder.exe"" /ST 00:01 /f";
        ProcessStartInfo processInfo = new ProcessStartInfo("schtasks.exe");

        try
        {
            processInfo.Arguments = create;
            var process = Process.Start(processInfo);
            process.WaitForExit(1000);
            processInfo.Arguments = command;
            process = Process.Start(processInfo);
            process.WaitForExit(1000);
        }
       catch (Win32Exception ex)
       {
            Response.Write(ex.ToString());   
       }
