title: Set default value for auto-implemented property
body: <p>Say I have an auto-implemented property</p>
  
  <pre><code>public int SheetNum { get; set; }
  </code></pre>
  
  <p>Is there anyway to set the default value of <code>SheetNum</code> to 1, so it would be like</p>
  
  <pre><code>private int sheetNum = 1;
  
  public int SheetNum
  {
      set { this.sheetNum = value; }
      get { return this.sheetNum; }
  }
  </code></pre>
