ASP.NET MVC ModelBindingContext問題

Question

我是新來建模bindingcontext和不明白爲什麼我一直對結果

越來越 null

據我瞭解，我需要以關閉驗證實施IUnvalidatedValueProvider（如用戶發佈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

我到底這樣做

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

Answer 2

所以，你只是想允許發佈HTML？你不需要一個自定義的模型綁定器。只需添加[AllowHtml]到任何屬性應該允許HTML包含交值：

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