Process.ExitTime Property

Definition

Namespace:

System.Diagnostics

Assembly:

System.Diagnostics.Process.dll

Source:

Process.cs

Gets the time that the associated process exited.

public:
 property DateTime ExitTime { DateTime get(); };

public DateTime ExitTime { get; }

member this.ExitTime : DateTime

Public ReadOnly Property ExitTime As DateTime

Property Value

DateTime

A DateTime that indicates when the associated process was terminated.

Exceptions

NotSupportedException

You are trying to access the ExitTime property for a process that is running on a remote computer. This property is available only for processes that are running on the local computer.

Examples

The following code example creates a process that prints a file. The process raises the Exited event when it exits, and the event handler displays the ExitTime property and other process information.

using System;
using System.Diagnostics;
using System.Threading.Tasks;

class PrintProcessClass
{
    private Process myProcess;
    private TaskCompletionSource<bool> eventHandled;

    // Print a file with any known extension.
    public async Task PrintDoc(string fileName)
    {
        eventHandled = new TaskCompletionSource<bool>();

        using (myProcess = new Process())
        {
            try
            {
                // Start a process to print a file and raise an event when done.
                myProcess.StartInfo.FileName = fileName;
                myProcess.StartInfo.Verb = "Print";
                myProcess.StartInfo.CreateNoWindow = true;
                myProcess.EnableRaisingEvents = true;
                myProcess.Exited += new EventHandler(myProcess_Exited);
                myProcess.Start();
            }
            catch (Exception ex)
            {
                Console.WriteLine($"An error occurred trying to print \"{fileName}\":\n{ex.Message}");
                return;
            }

            // Wait for Exited event, but not more than 30 seconds.
            await Task.WhenAny(eventHandled.Task,Task.Delay(30000));
        }
    }

    // Handle Exited event and display process information.
    private void myProcess_Exited(object sender, System.EventArgs e)
    {
        Console.WriteLine(
            $"Exit time    : {myProcess.ExitTime}\n" +
            $"Exit code    : {myProcess.ExitCode}\n" +
            $"Elapsed time : {Math.Round((myProcess.ExitTime - myProcess.StartTime).TotalMilliseconds)}");
        eventHandled.TrySetResult(true);
    }

    {
        // Verify that an argument has been entered.

        }

        PrintProcessClass myPrintProcess = new PrintProcessClass();
        await myPrintProcess.PrintDoc(args[0]);
    }

Remarks

If the process has not terminated, attempting to retrieve the ExitTime property throws an exception. Use HasExited before getting the ExitTime property to determine whether the associated process has terminated.
