winform简单缓存类实例

本文实例讲述了winform简单缓存类。分享给大家供大家参考。具体如下：

public partial class form3 : form
{
  //缓存类
  system.web.caching.cache cache;
  public form3()
  {
   initializecomponent();
   string sql = "select top 1000 * from infomation";
   datatable datatable = dbhelper.getdatatable(sql, conntype.menu);
   datagridview1.datasource = datatable;
   cache = system.web.httpruntime.cache;
   cache.insert("infomation", datatable);
  }
  private void button1_click(object sender, eventargs e)
  {
   if (cache != null) {
    datatable table = cache["infomation"] as datatable;
    datagridview2.datasource = table;
   }   
  }
}

希望本文所述对大家的c#程序设计有所帮助。
