The following example demonstrates how to connect to a System Center Data Access service by using the credentials of the current user. The example also shows how to handle some common connection failures.

/// <summary>
/// Connects to an SDK Service by using the current user's credentials.
/// </summary>
using System;
using System.ServiceProcess;
using Microsoft.EnterpriseManagement;
using Microsoft.EnterpriseManagement.Common;


namespace SDKSamples
{
	class Program
	{
		static void Main(string[] args)
		{
			Console.WriteLine("Attempting to connect to the SDK Service by using the current user's credentials.");

			try
			{
				ManagementGroup mg = ManagementGroup.Connect("localhost");
				if (mg.IsConnected)
					Console.WriteLine("Connection succeeded.");
				else
					throw new InvalidOperationException("Not connected to an SDK Service.");
		}
			catch (ServerDisconnectedException sde)
			{
				Console.WriteLine("\nConnection failed. " + sde.Message);
				if (sde.InnerException != null)
					Console.WriteLine(sde.InnerException.Message);
			
				// Call custom method to prompt the user for credentials if needed.
			
		}
			catch (ServiceNotRunningException snr)
			{
				Console.WriteLine(snr.Message);

				// Make one attempt to start the service.
				System.ServiceProcess.ServiceController sc = new 
					ServiceController("MOMSDK", "localhost");

				Console.WriteLine("Attempting to start the SDK Service on " + "localhost" + ".");
				sc.Start();

				// Wait 20 seconds for it to enter the Running state.
				sc.WaitForStatus(ServiceControllerStatus.Running, new TimeSpan(0, 0, 20));

				if (sc.Status == ServiceControllerStatus.Running)
				{
					ManagementGroup mg = new ManagementGroup("localhost");
					Console.WriteLine("Connection succeeded.");
			}
				else
				{
					throw new InvalidOperationException("Unable to restart and connect to the SDK Service.");
			}
		}
	}
}
}

Instead of explicitly calling the Connect method, you can also instantiate a new ManagementGroup object by using the new keyword, as shown in the following example:

mg = new ManagementGroup(serverName);

is the same as:

mg = ManagementGroup.Connect(serverName);
