Manage All Windows Services

Step 1: Form Objects

Create a simple Windows application form and add the below objects:

private System.Windows.Forms.ListBox lstServices;
private System.Windows.Forms.Button btnStart;
private System.Windows.Forms.Button btnRestart;
private System.Windows.Forms.Button btnStop;
private System.Windows.Forms.Label lblTrace;

After arranging the form objects:

Step 2: Load All Windows Services

On the form Load event, add this code to retrieve all Windows services to an array and use foreach to add a service name to the list.

ServiceController[] allServices = ServiceController.GetServices();
foreach (ServiceController srv in allServices)
{
    lstServices.Items.Add(srv.ServiceName);
}

Step 3: Form Actions

private void btnStart_Click(object sender, EventArgs e)
{
    string strServiceName = "";
    try
    {
        strServiceName = lstServices.SelectedItem.ToString();
        ServiceController srv = new ServiceController(strServiceName);
        if (srv.Status != ServiceControllerStatus.Running)
        {
            srv.Start();
        }
    }
    catch (Exception ex)
    {
        //
    }
}

private void btnRestart_Click(object sender, EventArgs e)
{
    string strServiceName = "";
    try
    {
        strServiceName = lstServices.SelectedItem.ToString();
        ServiceController srv = new ServiceController(strServiceName);
        if (srv.Status != ServiceControllerStatus.Running)
        {
            srv.Refresh();
        }
     }
     catch (Exception ex)
     {
         //
     }
}

private void btnStop_Click(object sender, EventArgs e)
{
    string strServiceName = "";
    try
    {
        strServiceName = lstServices.SelectedItem.ToString();
        ServiceController srv = new ServiceController(strServiceName);
        if (srv.Status != ServiceControllerStatus.Stopped)
        {
            srv.Stop();
        }
    }
    catch (Exception ex)
    {
        //
    }
}

private void lstServices_Click(object sender, EventArgs e)
{
    string strServiceName = "";
    string strServiceStat = "";
    try
    {
        strServiceName = (sender as ListBox).SelectedItem.ToString();
        ServiceController srv = new ServiceController(strServiceName);
        strServiceStat = srv.Status.ToString();

        lblTrace.Text = strServiceName + "      ->  " + strServiceStat;

    }
    catch (Exception ex)
    {
        //
    }
}
