static class/method not recognized within namespace

static class/method not recognized within namespace

• matthew_arena

  I'll agree with James: seeing the code would make this easier.

  Another hunch:

  If Utilities is a class, you must use the namespace:

  using MyNamespace;

  And scope the method call using the class name:

  Utilities.MyCoolMethod(...);

  Hope that helps.

  The lines in bold. Error text (for both lines):  The name 'MotorUtilities' does not exist in the current context  
  
  The MotorUtilities class is defined in a file named MotorUtilities.cs.

  I can tell you what's wrong with your code, if you don't let me see it....

  Things to check:

  Is the class declared public

  Is the method declared public

  What line is the compiler complaining about And what is the error message

  Is MotorUtilities in a different project The only way I have been able to replicate the problem you are seeing is by putting the MotorUtilities class in its own project and then not referencing it from the Forms application project.

  Jonathan,

  The 'static' modifier does not work like Java's static import feature. The static modifier is applied to a class, and indicates to the compiler that the class is a static holder class, that is, a class that contains only static members. However, you can't 'import' that class like a namespace, you will still need to prefix any methods in the static class with the class name itself.

  Regards

  David

  Many thanks to everyone for their posts. I believe I'm following everything that's been suggested, but the compiler still complains. I apologize for not posting code sooner but as it is somewhat lengthy and the concept (supposedly) simple I thought perhaps there might be something very basic I was missing (being new to C#).
  
  Below is the utility class snippet followed by code from the form class (with the utility method highlighted in bold):
  
  

  using System;
  namespace RCAWS_GUI
  {
  public static class MotorUtilities
  {
  unsafe static public byte[] convertMotorData(MotorType type, int rawData)
  {
  //deletia
  }
  }
  }
  
  

  The form class (which is o/w lengthy, hence the abbreviations) calling this method is declared so:
  
  

  using System;
  using System.Collections.Generic;
  using System.ComponentModel;
  using System.Data;
  using System.Drawing;
  using System.Text;
  using System.Windows.Forms;
  using IbisTekUtilities;
  using System.Net;
  using System.Diagnostics;
  using System.Net.Sockets;
  using System.IO;
  using System.Threading;
  
  
  namespace RCAWS_GUI
  {
  public partial class frmMain : Form
  {
  ButtonState prevDeadmanState = ButtonState.RELEASED;
  

  int prevLeftJoyX = 128;
  int prevLeftJoyY = 128;
  
  

  // deletia
  
  // ------------------------------------------------------------
  // Left Analog Joystick
  // The left joystick is mapped to Motor Control.
  // ------------------------------------------------------------
  void gamepad_leftAnalogJoyMoved(int axisX, int axisY)
  {
  
  byte[] data = new byte[4];
  
  // Only do something if the deadman switch is pressed
  
  if (prevDeadmanState == ButtonState.PRESSED)
  {
  if (axisX != 128)
  // joystick is pushed left or right of center
  {
  prevLeftJoyX = axisX;
  data = MotorUtilities.convertMotorData(MotorType.EL, axisY);
  }
  
  if (axisY != 128)
  // joystick is pushed up or down of center
  {
  prevLeftJoyY = axisY;
  data = MotorUtilities.convertMotorData(MotorType.EL, axisY);
  }
  } // END if deadman PRESSED
  
  } // end gamepad_leftAnalogJoyMoved
  
  // deletia
  
  } // END class Form
  
  } // END namespace RCAWS_GUI
  

  
  
  
  Again, many thanks to everyone for their input. I'm certain there is something blatantly obvious to someone who's not a newbie.
