CreateEventSource即使在Admin帐户下也会生成异常

我不知道这是否是解决问题的最佳方法,但它确实有效,我找不到更好的解决方案:

// ---- Create Event Log Source ---------------------------------
//
// returns True if is it created or already exists.
//
// Only administrators can create event logs.

static public bool CreateEventLogSource()
{
    System.Diagnostics.Debug.WriteLine("CreateEventLogSource....");

    try
    {
        // this call is looking for this RegKey: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\EventLog\Application\<app Name>
        if (EventLog.SourceExists(Application.ProductName))
        {
            System.Diagnostics.Debug.WriteLine("Log exists, returning true.");
            return true;
        }
    }
    catch (System.Security.SecurityException)
    {
        // it could not find the EventLog Source and we are not admin so this is thrown 
        // when it tries to search the Security Log. 
        // We know it isn't there so ignore this exception
    }

    System.Diagnostics.Debug.WriteLine("EventLog Source doesn't exist....try to create it...");

    if (new WindowsPrincipal(WindowsIdentity.GetCurrent()).IsInRole(WindowsBuiltInRole.Administrator))
    {
        System.Diagnostics.Debug.WriteLine("Running as Admin....trying to create....");
        try
        {
            EventLog.CreateEventSource(Application.ProductName, "Application");

            System.Diagnostics.Debug.WriteLine("Successfully create EventLogSource");
            return true;
        }
        catch (Exception Exp)
        {
            MessageBox.Show("Error Creating EventLog Source: " + Exp.Message, Application.ProductName);
            return false;
        }
    }
    else
    {
        System.Diagnostics.Debug.WriteLine("Need to restart with admin roles");

        ProcessStartInfo AdminProcess = new ProcessStartInfo();
        AdminProcess.UseShellExecute = true;
        AdminProcess.WorkingDirectory = Environment.CurrentDirectory;
        AdminProcess.FileName = Application.ExecutablePath;
        AdminProcess.Verb = "runas";

        try
        {
            Process.Start(AdminProcess);
            return false;
        }
        catch
        {
            MessageBox.Show("The EventLog source was NOT created", Application.ProductName);
            // The user refused to allow privileges elevation.
            return false;
        }
    }
}

在此调用:

static void Main(string[] args)
{
     if (CreateEventLogSource() == false)
          return;
