c# - 超时执行shell c#

Question

大家好我已经创建了一个小应用程序来使用命令执行“命令提示符”到目前为止我创建了一个简单的线程 sleep 方法

public static string Executecmd(string command, int sleepSec) {
    try {
        string result = null;
        System.Threading.Thread objThread = new System.Threading.Thread(delegate() {
            result = ExecuteCommandSync(command);
        });
        objThread.IsBackground = true;
        objThread.Start();
        while (objThread.IsAlive == true) {
            System.Threading.Thread.Sleep(sleepSec * 1000);
            objThread.Abort();
        }
        return result;
    }
    catch (Exception x) {
        Console.WriteLine(x.Message + "\n" + x);
        return null;
    }
}

它工作正常，但即使命令执行完成，它也会保持 sleep 状态，直到线程 sleep 完成，所以我的问题是如何创建一个方法来执行它并 sleep 5 秒，如果它完成它会停止，否则等待 5秒然后中止

使用Thread.Join有时间跨度。

    System.Threading.Thread objThread = new System.Threading.Thread(delegate() {
        result = ExecuteCommandSync(command);
    });
    objThread.IsBackground = true;
    objThread.Start();

    //Waits here for "sleepSec" seconds or until the thread finishes, whichever is shorter.
    if(objThread.Join(new TimeSpan.FromSeconds(sleepSec)) == false)
    {
        //Only executes this code of the thread did not finish before the timeout.
        objThread.Abort();
    }
