Method, Class, Object Reference

[C# Programming]

Why does my attempt to use a method called "Start_Data_Command_04" in this file produce the stated error ? (I'll list the error immediately after the code)

File Name: Form1.cs
namespace George_Washington{ public partial class Form1 : Form { ///Lots of other stuff /// /// /* *************************************************************************** * * This button Will Start The Data Flood * * *************************************************************************** */ void Button4_Start_Data_Click(object sender, EventArgs e) { The_User_Clicked_A_Button_Called.Start_Data_Command_04(); ////Error Is here } }}

The method named "Start_Data_Command_04" is located in this file, and produces an error (no clue if they are related) of its own...

File name: The_User_Clicked_A_Button_Called.cs
namespace George_Washington{ public class The_User_Clicked_A_Button_Called { internal void Start_Data_Command_04() { UART.send_command (////The Error Is Flagged right here Protocol_Packets_01.BARN_Command_04_Start_Data_Flood, 0, Protocol_Packets_01.BARN_Command_04_Start_Data_Flood.Length ) ; } }}

Error 1 An object reference is required for the non-static field, method, or property 'SerialPortPractice_03.UART.send_command(byte[], int, int)'

No matter what word I put in front of the method; e.g., internal, private, public, static, whatever; I still get an error.


The actual method in question is here
File Name: UART.cs
namespace George_Washington{ class UART { public void send_command(byte[] The_Byte_Array, int Starting_Place, int Length) { The_Serial_Port_We_Are_Testing.Write( The_Byte_Array, Starting_Place, Length ) ; } } }
