You just need to set your return parameter's Direction property to ParameterDirection.ReturnValue, and after you execute your command get return parameter's value like that :

SqlParameter myReturnParam = command.Parameters.Add("@MyReturnValue", SqlDbType.Int);
myReturnParam.Direction = ParameterDirection.ReturnValue;

// Execute your Command here, and get the value of your return parameter :  

int myReturnValue = (int)command.Parameters["@MyReturnValue"].Value;

THIS IS WHAT I AM DOING

SSS IS ALWAYS RETURNING 1




Dim Connection As SqlClient.SqlConnection = CreateConnection()

        Dim Command As New SqlClient.SqlCommand

        With Command
            .Connection = Connection
            .CommandText = "spValidateLogin "
            .CommandType = CommandType.StoredProcedure

            .Parameters.AddWithValue("@username", UserName)

            .Parameters.AddWithValue("@password", Password)
            .Parameters.AddWithValue("@ipaddress", IPAddress)
            .Parameters.AddWithValue("@result", "1")

            Dim parameterResult As SqlClient.SqlParameter = New SqlClient.SqlParameter("@result", SqlDbType.Int)
            .Parameters.Add(parameterResult)
            parameterResult.Direction = ParameterDirection.ReturnValue


            .ExecuteNonQuery()
            Dim sss As Integer
            sss = Command.Parameters("@result").Value
'sss IS ALWAYS RETURNING 1

        End With

Here you need to follow:


     //Create command  
    SqlCommand Cmd = new SqlCommand("AddSomething", oConn);
    Cmd.CommandType = CommandType.StoredProcedure;

    SqlParameter oParam = Cmd.Parameters.AddWithValue("@zonename", sName);
    oParam = Cmd.Parameters.AddWithValue("@desc", sDesc);
    oParam = Cmd.Parameters.AddWithValue("@TheNewId", 0);
    oParam.Direction = ParameterDirection.Output;
 
    Cmd.ExecuteNonQuery();
 
    oConn.Close();
    int nTheNewId = Convert.ToInt32(Cmd.Parameters["@TheNewId"].Value);
    return nTheNewId;

For the case that gdupadhyay: explains, you need to set the parameter as OUTPUT parameter in the Stored Procedure.
CREATE PROCEDURE YourStoredProcedure
(
      @result INT OUTPUT
)
...

Open in new window


I think no need to explain, as you got it
sss = parameterResult.Value

Open in new window
