title: string <-> int/float conversion pain in .net winform
body: <p>the Text property of control on winform is always string type, so if i wanna expose property of other type for custom control,  i have to do the conversion as following, if i have dozens of properties to expose, it will be such pain for me.</p>
  
  <pre><code>  public int ImageGroupLength
      {
          get
          {
              return int.Parse(this.imageGroupLength.Text);
          }
          set
          {
              this.imageGroupLength.Text = value.ToString();
          }
      }
  </code></pre>
  
  <p>so, is there any elegant way to do the conversion?</p>
