  If your form has focus, you can handle the KeyDown event as followings:
  
  private void Form1_KeyDown(object sender, KeyEventArgs e)
  {
  switch (e.KeyCode)
  {
  case Keys.Up:
  case Keys.Down:
  case Keys.Left:
  case Keys.Right:
  MessageBox.Show(e.KeyCode.ToString());
  break;
  }
  }

  Overriding ProcessDialogKey method in your windows application, you can easily capture the arrow keys

  Eg:

  protected override bool ProcessDialogKey(Keys keyData)

  {

  if (keyData == Keys.Right)

  {

  //Your Code

  return true;

  }

  else if (keyData == Keys.Left)

  {

  //Your Code

  return true;

  }

  else if (keyData == Keys.Up)

  {

  //Your Code

  return true;

  }

  else if (keyData == Keys.Down)

  {

  //Your Code

  return true;

  }

  else

  {

  return base.ProcessDialogKey(keyData);

  }

  }

  Hi, Cavetroll

  As Jared TW described, but you must add the keydown event in form_load first, the example follows:

              private void Form1_Load(object sender, EventArgs e)

          {

              //// Set these when the form loads:

              //// Have the form capture keyboard events first.

              this.KeyPreview = true;

              //// Assign the event handler to the form.

              this.KeyDown += new System.Windows.Forms.KeyEventHandler(this.Form1_KeyDown);

          }

          private void Form1_KeyDown(object sender, KeyEventArgs e)

          {

              switch (e.KeyCode)

              {

                  case Keys.Up://the code you need when presses up

                  case Keys.Down://the code you need when presses down

                  case Keys.Left://the code you need when presses left

                  case Keys.Right://the code you need when presses right

                  MessageBox.Show(e.KeyCode.ToString());

                      break;

              }

          }
