How to use the return value from the output property in the parameters of a data query

Data public int addmessage (int moduleid, int fatherid, string userName, string title, string body, string face) {

if (Username.length < 1) {
UserName = "Unknown";
}

Create Instance of Connection and Command Object
SqlConnection myconnection = new SqlConnection (configurationsettings.appsettings["connectionString"]);
SqlCommand mycommand = new SqlCommand ("Up_posttopic", MyConnection);

Mark the Command as a sproc
myCommand.CommandType = CommandType.StoredProcedure;

Add Parameters to SPROC
SqlParameter parameteritemid = new SqlParameter ("@ItemID", SqlDbType.Int, 4);
Parameteritemid.direction = ParameterDirection.Output;
MYCOMMAND.PARAMETERS.ADD (Parameteritemid);

SqlParameter Parameterfatherid = new SqlParameter ("@FatherID", SqlDbType.Int, 4);
Parameterfatherid.value = Fatherid;
MYCOMMAND.PARAMETERS.ADD (Parameterfatherid);

SqlParameter Parametermoduleid = new SqlParameter ("@ModuleID", SqlDbType.Int, 4);
Parametermoduleid.value = ModuleID;
MYCOMMAND.PARAMETERS.ADD (Parametermoduleid);

SqlParameter parameterusername = new SqlParameter ("@CreatedByUser", SqlDbType.NVarChar, 100);
Parameterusername.value = UserName;
MYCOMMAND.PARAMETERS.ADD (Parameterusername);

SqlParameter parametertitle = new SqlParameter ("@Title", SqlDbType.NVarChar, 100);
Parametertitle.value = title;
MYCOMMAND.PARAMETERS.ADD (Parametertitle);

SqlParameter parameterbody = new SqlParameter ("@Content", SqlDbType.NVarChar, 4000);
Parameterbody.value = body;
MYCOMMAND.PARAMETERS.ADD (Parameterbody);

SqlParameter parameterface = new SqlParameter ("@Face", SqlDbType.NVarChar, 100);
Parameterface.value = face;
MYCOMMAND.PARAMETERS.ADD (Parameterface);

Myconnection.open ();
Mycommand.executenonquery ();
Myconnection.close ();

return (int) Parameteritemid.value;
}
