asp. net Simple Realization of Page Skin Change Method

In this paper, an example is given to describe the simple method of page skinning by asp. net. Share it for your reference, as follows:

Here to achieve the effect of page skin change, you can add the corresponding style to html form

private string _StyleClass;
public string StyleClass
{
  get { return _StyleClass; }
  set { _StyleClass = value; }
}
private void StyleForm()
{
  HtmlForm Form1 = this.FindControl("form1") as HtmlForm;
  Form1.Attributes.Add("class", _StyleClass);
}
protected override void OnPreRender(EventArgs e)
{
  // Control rendering calls methods 
  StyleForm();
  base.OnPreRender(e);
}

I hope this paper is helpful to everyone's asp. net programming.
