在ASP.NET C#中将对象转换为单选按钮列表 [英] convert object into radiobuttonlist in asp.net C#

问题描述

如何将对象转换为RadioButtonList

how to convert an object into RadioButtonList

推荐答案

如果您的对象属于RadioButtonList 类型，则只需将其转换为RadioButtonList

RadioButtonList onew = (RadioButtonList)ob;

如果它不是object类型，则不能.

If your object is of type RadioButtonList you can simply cast it into a RadioButtonList

RadioButtonList onew = (RadioButtonList)ob;

If it is not of type object, you cannot.

假定它是一个以RadioButtonList开头或从RadioButtonList派生的单选按钮列表，然后对其进行转换.如果不是，那你就不能.

Assuming it is a radio buttonlist to start with, or devived from a RadioButtonList, then cast it. If it isn''t, then you can''t.

RadioButtonList rbl = myObject as RadioButtonList;
if (rbl != null)
   {
   ...
   }

谢谢您的重放，我使用了它，但是具有空值"myobject"的"rbl"包含RadioButtonList的ID"

啊!您应该说这是网络-会有所帮助.

查看 Control.FindControl方法 [

"Thank you for your replay ,i use this but the ''rbl'' having null value ''myobject'' contain ID of RadioButtonList"

Ah! You should have said this was web - it would have helped.

Look at the Control.FindControl Method[^]
