要检查MyBat.bat文件是否在C＃中运行

Question

How can I check through C# code, if MyBat.bat file is running or not in the system.

I have tried this but not working properly.Please suggest some other way.

Process proc = new Process();
proc.StartInfo.FileName = @"D:\MyBat.bat";
if (proc.Start())
{
     Console.Write("This is bat files Open!.");
}
else
{
    Console.Write("Welcome");
}

I only want to check MyBat.bat file is running in the system or not. Because .bat file run in Command Prompt so how can i verify that MyBat.bat file is running.

Answer 1

You should invoke your batch file via cmd.exe /c , not directly.

so:

var command = "foo.bat";
Process p = new Process(){
    StartInfo = new ProcessStartInfo("cmd.exe", "/c " + command)
};
var started = p.Start();

if(started)
{
    Console.WriteLine("started");
    var sync = true; //or false, see below
    if(sync)
    {
        //either wait synchronously
        p.WaitForExit();
        Console.WriteLine("finished");
    }
    else
    {
        //or wait for an exit event asynchronously
        p.Exited += (a, b) => { Console.WriteLine("finished"); }
    }


}
else
{
    Console.WriteLine("not started");
}

If you want to know right now, you can check the HasExited property.

var isRunning = !myProcess.HasExited;

If it's a quick process, just wait for it.

myProcess.WaitForExit();

If you're starting one up in the background, subscribe to the Exited event after setting EnableRaisingEvents to true.

myProcess.EnableRaisingEvents = true;

myProcess.Exited += (sender, e) => { MessageBox.Show("Process exited"); };
