推荐答案

什么是p？



您使用RadioButtonFor绑定到您的模型，所以你的视图的模型将是一个具有Lang_id字段的类，你绑定它就像

What is "p"?

You use RadioButtonFor to bind to your model, so your view's model will be a class that has a Lang_id field and you bind to it like

@Html.RadioButtonFor(model => model.Lang_id, "1", Model.Lang_id == '1' ? new { @Checked = "checked" } : null) English
@Html.RadioButtonFor(model => model.Lang_id, "2", Model.Lang_id == '2' ? new { @Checked = "checked" } : null) Hindi
@Html.RadioButtonFor(model => model.Lang_id, "3", Model.Lang_id == '3' ? new { @Checked = "checked" } : null)

行动将是

The action will then be

[HttpPost]
public ActionResult UpdateAssistanceScheme(YourModelTypeHere model) 
{
   // value is in model.Lang_id
}
