Script Task - Console.writeline alternative

I am using C# in the script task and i am using console.write line to show the message but when i execute the script task it doesn't show up any message but the package is running fine. How to pass the pop up message thru email task.

Do i need to use any other thing rather than the Console.writeline? Below is the c# code that i am using in the script task.How to send the  pop up message thru email task.

		The execution engine calls this method when the task executes.
		To access the object model, use the Dts property. Connections, variables, events,

		To reference a variable, call Dts.Variables["MyCaseSensitiveVariableName"].Value;
		To post a log entry, call Dts.Log("This is my log text", 999, null);
		To fire an event, call Dts.Events.FireInformation(99, "test", "hit the help message", "", 0, true);

		To use the connections collection use something like the following:
		ConnectionManager cm = Dts.Connections.Add("OLEDB");
		cm.ConnectionString = "Data Source=localhost;Initial Catalog=AdventureWorks;Provider=SQLNCLI10;Integrated Security=SSPI;Auto Translate=False;";

		Before returning from this method, set the value of Dts.TaskResult to indicate success or failure.
