我怎么知道最后一次OutputDataReceived何时到达？

using System;
using System.Diagnostics;

namespace OutputDataReceivedExample
{
    class Program
    {
        static void Main(string[] args)
        {
            Process process = new Process();
            process.StartInfo.FileName = "your_command_here";
            process.StartInfo.Arguments = "your_arguments_here";
            process.StartInfo.UseShellExecute = false;
            process.StartInfo.RedirectStandardOutput = true;
            process.OutputDataReceived += (sender, eventArgs) =>
            {
                Console.WriteLine($"Output: {eventArgs.Data}");
            };

            process.Start();
            process.BeginOutputReadLine();
            process.WaitForExit();

            Console.WriteLine($"OutputDataReceived event occurred at: {process.ExitTime}");
        }
    }
}
