can a method with return type as list be called from a thread

Question

I have a method, shown below, which calls a service.

How can I run this method through thread?

public List<AccessDetails> GetAccessListOfMirror(string mirrorId,string server)
{
    List<AccessDetails> accessOfMirror = new List<AccessDetails>();
    string loginUserId = SessionManager.Session.Current.LoggedInUserName;
    string userPassword = SessionManager.Session.Current.Password;

    using (Service1Client client = new Service1Client())
    {
        client.Open();
        accessOfMirror = client.GetMirrorList1(mirrorId, server, null);
    }

    return accessOfMirror;
}

Answer 1

In C# 3.5 or 4.0 you can do this.

var task = Task.Factory.StartNew<List<AccessDetails>>(() => GetAccessListOfMirror(mirrorId,server))
.ContinueWith(tsk => ProcessResult(tsk));

private void ProcessResult(Task task)
{
    var result = task.Result;
}

In C# 4.5 there's the await/async keywords which is some sugar for above

public async Task<List<AccessDetails>> GetAccessListOfMirror(string mirrorId,string server)

var myResult = await GetAccessListOfMirror(mirrorId, server)

Try something like this:

public async Task<List<AccessDetails>> GetAccessListOfMirror(string mirrorId, string server)
    {
        List<AccessDetails> accessOfMirror = new List<AccessDetails>();
        string loginUserId = SessionManager.Session.Current.LoggedInUserName;
        string userPassword = SessionManager.Session.Current.Password;


        using (Service1Client client = new Service1Client())
        {
            client.Open();
            Task<List<AccessDetails>> Detail = client.GetMirrorList1(mirrorId, server, null);
            accessOfMirror = await Detail;

        }


        return accessOfMirror;
    }
