我在反射器中跟踪代码,发现生成值的方式不同.不使用相同的帮助方法.
LabelFor用途HtmlHelper.GenerateIdFromName和TextBoxFor用途TagBuilder#GenerateId.
有没有人知道这个的原因,或解决方法(除了编写你自己的整套输入/ textarea /选择助手)?或者这是一个错误?
更新:
因为我总是使用标签文本的第二个参数为标签使用html帮助器,我修改它以使用与表单字段助手相同的id生成代码.

// The main part of this code is taken from the internal code for Html.LabelFor<TModel, TValue>(...).
var metaData = ModelMetadata.FromLambdaExpression(expression, helper.ViewData);
var fieldName = ExpressionHelper.GetExpressionText(expression);
