我正在尝试在我的 asp.net mvc 应用程序中使用流利的 html 和 spark 视图引擎。我已经分配了正确的基类,添加了程序集,当我这样做时。TextBox("MyProperty") 它工作正常。但是,当我尝试使用 this.TextBox(m=>m.MyProperty) 时出现以下异常。知道是什么原因造成的吗?

例外:

Dynamic view compilation failed.

如果你真的分配了正确的基类,那么这个异常通常意味着你的 lambda 表达式中有无效的属性。仔细检查一下。您实际上没有显示,也没有显示您的火花视图或代码。但是,作为一个例子,如果你有

public string Name { get; set; }

并使用

this.Hidden(x => x.Name1)

你会得到这个错误(后面跟着另一个异常)。
