Get my winforms app's uptime?

Question

Hello all,

Anyone aware of a method to get the total uptime of my own .net app?

Didn't find in Google :(

Answer 1

As far as I know, no such convenience method exists You can calculate the time elapsed since the application started running by recording the start time and then computing the difference between the current time and the start time. Here's a sample code in C#:

public static void Main()
{
    startTime = DateTime.Now;
        ・
        ・
        ・
    TimeSpan upTime = DateTime.Now - startTime;
    Console.WriteLine("Application uptime: {0}", upTime);
}

Answer 2

It should be as simple as the declaration of a Stopwatch variable.

Public Class Form1
    Private runTime As Stopwatch = Stopwatch.StartNew

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        'blah
    End Sub
End Class

Answer 3

A fuller example.

Public Class Form1

    Private runTime As Stopwatch = Stopwatch.StartNew

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        'show run time
        ' Standard TimeSpan format strings
        ' https://learn.microsoft.com/en-us/dotnet/standard/base-types/standard-timespan-format-strings

        'Label1.Text = runTime.Elapsed.ToString("c")

        ' Custom TimeSpan format strings
        ' https://learn.microsoft.com/en-us/dotnet/standard/base-types/custom-timespan-format-strings

        '                         days hours minutes seconds milliseconds
        Label1.Text = runTime.Elapsed.ToString("d\.hh\:mm\:ss\.fff")
    End Sub
End Class
