如何进行动态的数据类型转换?

Question

public void DataBind(WebControl control_c)
        {
            string type_s = control_c.GetType().ToString();
            string [] types=type_s.Split('.');
            type_s=types[types.Length-1];
            switch (type_s)
            {
                case "DataGrid":
                    DataGrid c = (DataGrid)control_c;
                    break;
                case "GridView":
                    GridView c = (GridView)control_c;
                    break;
                case "Repeater":
                    Repeater c=(Repeater)control_c;
                    break;
                default:
                    throw System.Exception;
            }
            control_c.DataSource = this.DataSource;
        }以上代码是错的,一直没有找到好的解决方法,高手们快来解答吧!
我的意思是:control_c有可能是以上类型,有没有办法获取它实际的类型,并转换过来!

Answer 1

有意义啊,不转换的话无法使用DataSource属性,因为WebControl不存在此属性!

Answer 2

public void DataBind(WebControl control_c)
    {        System.Reflection.PropertyInfo p = control_c.GetType().GetProperty("DataSource");
        p.SetValue(control_c, 数据源, null);
        
    }
