问题描述
我有以下类:
public class Movie
{
string Name get; set;
string Director get; set;
IList<String> Tags get; set;
}
如何绑定标签属性?一个简单的开关输入的文本,以逗号分隔。但是,只有到控制器我'在作弄我,没有为穴施。
谢谢
How do I bind the tags properties? to a simple imput text, separated by commas. But only to the controller I'am codding, no for the hole application. Thanks
推荐答案
您可以写一个自定义的模型绑定启动:
You could start with writing a custom model binder:
public class MovieModelBinder : DefaultModelBinder
{
protected override void SetProperty(ControllerContext controllerContext, ModelBindingContext bindingContext, System.ComponentModel.PropertyDescriptor propertyDescriptor, object value)
{
if (propertyDescriptor.Name == "Tags")
{
var values = bindingContext.ValueProvider.GetValue(propertyDescriptor.Name);
if (values != null)
{
value = values.AttemptedValue.Split(',');
}
}
base.SetProperty(controllerContext, bindingContext, propertyDescriptor, value);
}
}
和然后将其应用到这是应该接收输入一个特定的控制器的操作:
and then applying it to a particular controller action which is supposed to receive the input:
public ActionResult Index([ModelBinder(typeof(MovieModelBinder))] Movie movie)
{
// The movie model will be correctly bound here => do some processing
}
现在,当您发送以下GET请求:
Now when you send the following GET request:
/index?tags=tag1,tag2,tag3&name=somename&director=somedirector
或使用HTML POST请求&LT;形式为GT;
:
Or POST request with an HTML <form>
:
@using (Html.BeginForm())
{
<div>
@Html.LabelFor(x => x.Name)
@Html.EditorFor(x => x.Name)
</div>
<div>
@Html.LabelFor(x => x.Director)
@Html.EditorFor(x => x.Director)
</div>
<div>
@Html.LabelFor(x => x.Tags)
@Html.TextBoxFor(x => x.Tags)
</div>
<input type="submit" value="OK" />
}
的电影
模式应该是在控制器的行动,只有这里面的控制器操作正确绑定。
The Movie
model should be bound correctly in the controller action and only inside this controller action.
