ASP.NET MVC ModelBindingContext问题

Question

我是新来建模bindingcontext和不明白为什么我一直对结果

越来越 null

据我了解，我需要以关闭验证实施IUnvalidatedValueProvider（如用户发布html）。

public class AccountFormBinder : IModelBinder 
{ 
    public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) 
    { 
     //Cast the value provider to an IUnvalidatedValueProvider, which allows to skip validation 
     IUnvalidatedValueProvider provider = bindingContext.ValueProvider as IUnvalidatedValueProvider; 
     var result = provider.GetValue(bindingContext.ModelName,true); 
     return result.AttemptedValue; 
    } 
} 

Answer 1

我到底这样做

HttpRequestBase request = controllerContext.HttpContext.Request; 
var re = request.Unvalidated("CMessage");

所以，你只是想允许发布HTML？你不需要一个自定义的模型绑定器。只需添加[AllowHtml]到任何属性应该允许HTML包含交值：

public class MyViewModel 
{ 
    ... 
    [AllowHtml] 
    [DataType(DataType.Html)] 
    public string Content { get; set; } 
    ... 
}
