似乎MVC 2 RTM目前不提供此function。 您可以尝试以下扩展方法：

  public static MvcHtmlString ValidationMessageFor(this HtmlHelper htmlHelper, string prefix, Expression> expression) { return ValidationMessageFor(htmlHelper, prefix, expression, null, new RouteValueDictionary()); } public static MvcHtmlString ValidationMessageFor(this HtmlHelper htmlHelper, string prefix, Expression> expression, string validationMessage) { return ValidationMessageFor(htmlHelper, prefix, expression, validationMessage, new RouteValueDictionary()); } public static MvcHtmlString ValidationMessageFor(this HtmlHelper htmlHelper, string prefix, Expression> expression, string validationMessage, object htmlAttributes) { return ValidationMessageFor(htmlHelper, prefix, expression, validationMessage, new RouteValueDictionary(htmlAttributes)); } public static MvcHtmlString ValidationMessageFor(this HtmlHelper htmlHelper, string prefix, Expression> expression, string validationMessage, IDictionary htmlAttributes) { return htmlHelper.ValidationMessage(String.Format("{0}.{1}", prefix, ExpressionHelper.GetExpressionText(expression)), validationMessage, htmlAttributes); } public static MvcHtmlString HiddenFor(this HtmlHelper htmlHelper, string prefix, Expression> expression) { return HiddenFor(htmlHelper, prefix, expression, (IDictionary)null); } public static MvcHtmlString HiddenFor(this HtmlHelper htmlHelper, string prefix, Expression> expression, object htmlAttributes) { return HiddenFor(htmlHelper, prefix, expression, new RouteValueDictionary(htmlAttributes)); } public static MvcHtmlString HiddenFor(this HtmlHelper htmlHelper, string prefix, Expression> expression, IDictionary htmlAttributes) { return htmlHelper.Hidden(String.Format("{0}.{1}", prefix, ExpressionHelper.GetExpressionText(expression)), ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData).Model, htmlAttributes); /*return HiddenHelper(htmlHelper, ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData).Model, false, ExpressionHelper.GetExpressionText(expression), htmlAttributes);*/ } public static MvcHtmlString TextAreaFor(this HtmlHelper htmlHelper, string prefix, Expression> expression) { return TextAreaFor(htmlHelper, prefix, expression, (IDictionary)null); } public static MvcHtmlString TextAreaFor(this HtmlHelper htmlHelper, string prefix, Expression> expression, object htmlAttributes) { return TextAreaFor(htmlHelper, prefix, expression, new RouteValueDictionary(htmlAttributes)); } public static MvcHtmlString TextAreaFor(this HtmlHelper htmlHelper, string prefix, Expression> expression, IDictionary htmlAttributes) { if (expression == null) { throw new ArgumentNullException("expression"); } string value; var modelMetadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData); if (modelMetadata.Model != null) value = modelMetadata.Model.ToString(); else value = String.Empty; return htmlHelper.TextArea(String.Format("{0}.{1}", prefix, ExpressionHelper.GetExpressionText(expression)), value, htmlAttributes); } public static MvcHtmlString TextBoxFor(this HtmlHelper htmlHelper, string prefix, Expression> expression) { return TextBoxFor(htmlHelper, prefix, expression, (IDictionary)null); } public static MvcHtmlString TextBoxFor(this HtmlHelper htmlHelper, string prefix, Expression> expression, object htmlAttributes) { return TextBoxFor(htmlHelper, prefix, expression, new RouteValueDictionary(htmlAttributes)); } public static MvcHtmlString TextBoxFor(this HtmlHelper htmlHelper, string prefix, Expression> expression, IDictionary htmlAttributes) { return htmlHelper.TextBox(String.Format("{0}.{1}", prefix, ExpressionHelper.GetExpressionText(expression)), ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData).Model, htmlAttributes); } 

你总是可以设置htmlAttributes ，虽然它不是最干净的方法。
并且，您必须在所有助手中完成此操作。

  <%: Html.TextBoxFor(model => model.Login, new { @id = "prefixLogin" }) %> 

对于同样的问题有不同的解决方案..我已经创建了一个新的mvc测试项目，并将整个视图的web.config复制到我收到此错误的旧项目中，解决了
