C# stored procedure with parameters

I am receiving an error in my application and i can not figure out how to resolve it. Here is the code:

SqlConnection myConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["DBConnection"].ConnectionString);
myConnection.Open();

SqlCommand cmd = new SqlCommand("SELECT ServerIP FROM Servers", myConnection);

SqlDataReader rdr = cmd.ExecuteReader();

if (rdr.HasRows)
{
   while (rdr.Read())
   {
      string serverIP = rdr["ServerIP"].ToString();
      ScheduledTasks st = new ScheduledTasks(@"\\" + serverIP);
      string[] taskNames = st.GetTaskNames();

      foreach (string name in taskNames)
      {
         Task t = st.OpenTask(name);
         var status = t.Status;
         var recentRun = t.MostRecentRunTime;
         var nextRun = t.NextRunTime;
         var appName = t.ApplicationName;

         SqlConnection myConnection2 = new SqlConnection(ConfigurationManager.ConnectionStrings["DBConnection"].ConnectionString);
         SqlCommand myCommand2 = new SqlCommand("sp_AddScheduledTasks", myConnection2);

         try
         {
            myConnection2.Open();
            myCommand2.CommandType = CommandType.StoredProcedure;
            myCommand2.Parameters.Add("@ID", SqlDbType.Int);
            myCommand2.Parameters["@ID"].Direction = ParameterDirection.Output;
            myCommand2.Parameters.Add("@ServerIP", SqlDbType.NVarChar, 20).Value = serverIP;
            myCommand2.Parameters.Add("@TaskName", SqlDbType.NVarChar, 50).Value = t;
            myCommand2.Parameters.Add("@MostRecentRun", SqlDbType.DateTime).Value = recentRun;
            myCommand2.Parameters.Add("@NextRunTime", SqlDbType.DateTime).Value = nextRun;
            myCommand2.Parameters.Add("@AppName", SqlDbType.NVarChar, 50).Value = appName;
            myCommand2.Parameters.Add("@Status", SqlDbType.NVarChar, 50).Value = status;

            int rows = myCommand2.ExecuteNonQuery();
         }
         finally
         {
            myConnection2.Close();

I think the problem is with this line:

myCommand2.Parameters.Add("@TaskName", SqlDbType.NVarChar, 50).Value = t;

t cannot be converted to a string. You could try t.Name or t.ToString() (not sure what properties are available on that class off the top of my head.)

  myCommand2.Parameters.Add("@TaskName", SqlDbType.NVarChar, 50).Value = t;

t is a Task not a string. This should probably by name.
