title: Not scoping static vars properly in C#
body: <p>I'm new to C# - this is nearly my first program. I'm trying to create some public static variables and constants to use anywhere in the program. The - wrong - way I have tried is to declare them in a separate class in the same namespace but they are out of context for the main program. It's a WPF application. The code looks like this:</p>
  
  <pre><code>namespace testXyz
  {
      class PublicVars
      {
          public const int BuffOneLength = 10000;
          public static int[] Buff1 = new int[BuffOneLength];
  
          public const int BuffTwoLength = 2500;
          public static int[] Buff2 = new int[BuffTwoLength];
  
          private void fillBuff1()
          {
              Buff1[0] = 8;
              Buff1[1] = 3;           
              //etc
          }
  
          private void fillBuff2()
          {
              Buff2[0] = 5;
              Buff2[1] = 7;           
              //etc
          }   
      }
  }
  </code></pre>
  
  <p>Second file:</p>
  
  <pre><code>namespace testXyz
  {
      public partial class MainWindow : Window
      {
          public MainWindow() 
          {
              InitializeComponent();
          }
  
          public static int isInContext = 0;
          int jjj = 0, mmm = 0;
  
          private void doSomething()
          {
              isInContext = 5;    // this compiles
              if (jjj &lt; BuffOneLength)    // "the name 'BuffOneLength' does not exist in the current context"
              {
                  mmm = Buff2[0]; // "the name 'Buff2' does not exist in the current context"
              }
          }
      }
  }
  </code></pre>
  
  <p>My actual program is much longer of course. I created the above WPF application exactly as shown to test this problem and I got these errors, also occurring in the real program. I really don't want to fill the arrays in the main program as they are very long and it would  mean much scrolling. I also want to have one place where I can declare certain public static variables. What is the right way to do this?</p>
