Question

您好我的模型中有CellPhone类型的字段int。

在视图中，我的CellPhone字段中有一个javascript掩码。当客户端发送页面的帖子时，我会收到类似的内容：

555-4789

但是这个值对于int类型来说不是有效值。无论如何，通过在绑定发生之前删除字符'-'来通知模型绑定器我想要“清理”数字？

可能是DataAnnotation还是别的什么？

Use custom model binder for that-

public class yourmodel
{
public int cellphone{get;set;}
}

Define custom model binder as
public class CustomBinder : IModelBinder
{
    public object BindModel(ControllerContext controllerContext, 
                            ModelBindingContext bindingContext)
    {
        HttpRequestBase request = controllerContext.HttpContext.Request;

        string[] phoneArray= request.Form.Get("CellPhone").split('-');

        string phone=phoneArray[0]+phoneArray[1];

        return new yourmodel
                   {
                       cellphone= convert.ToInt32(phone)
                   };
    }
} 


then in app_start register new created binder as
protected void Application_Start()
{

    ModelBinders.Binders.Add(typeof(yourmodel), new CustomBinder());
}

and in controller 
[HttpPost]
public ActionResult Index([ModelBinder(typeof(CustomBinder))] yourmodel model)
{

    //..processing code
}

排除绑定模型Asp.net MVC中的字符
