您可以使用Dictionary对象来存储键/值并将其绑定到RadioButtonList,如下所示:

        Dictionary<string, string> values = new Dictionary<string, string>();
        values.Add("key 1", "value 1");
        values.Add("key 2", "value 2");
        values.Add("key 3", "value 3");

        RadioButtonList radioButtonList = new RadioButtonList();
        radioButtonList.DataTextField = "Value";
        radioButtonList.DataValueField = "Key";
        radioButtonList.DataSource = values;
        radioButtonList.DataBind();

或者您也可以将项添加到RadioButtonList Items集合中,如下所示:

        radioButtonList.Items.Add(new ListItem("Text 1", "Value 1"));
        radioButtonList.Items.Add(new ListItem("Text 2", "Value 2"));
        radioButtonList.Items.Add(new ListItem("Text 3", "Value 3"));
