我知道它可以自动完成;
class Query
{
public int?[] Id { get; set; }
}
public ActionResult Index(Query q)
{
}
一些QueryString
/index?id=10&id=11
它完美无瑕。
但是在某些情况下,我只有可用的请求:
Reqest.RawUrl
是否可以使用内置解析来创建查询对象?
Query q = SomeMagicStuff<Query>(Request.RawUrl);
最佳答案
对的,这是可能的。如果您使用MVC,则可以使用MVC DefaultModelBinder
为这种情况编写一个函数:
public class MyModelBinder<T>
{
private ModelBindingContext modelBindingContext = new ModelBindingContext();
/// <summary>
/// Method to get model from QueryString
/// </summary>
/// <param name="request">HttpRequest</param>
/// <returns>T model</returns>
public static T GetModelFromQueryString(HttpRequest request)
{
modelBindingContext.ModelMetadata = ModelMetadataProviders.Current.GetMetadataForType(null, typeof(T));
modelBindingContext.ValueProvider = new NameValueCollectionValueProvider(request.QueryString, System.Globalization.CultureInfo.InvariantCulture);
IModelBinder mb = new DefaultModelBinder();
return (T)mb.BindModel(new ControllerContext(), modelBindingContext);
}
/// <summary>
/// Method to get model from FormColletion
/// </summary>
/// <param name="request">HttpRequest</param>
/// <returns>T model</returns>
public static T GetModelFromFormColletion(HttpRequest request)
{
modelBindingContext.ModelMetadata = ModelMetadataProviders.Current.GetMetadataForType(null, typeof(T));
modelBindingContext.ValueProvider = new NameValueCollectionValueProvider(request.Params, System.Globalization.CultureInfo.InvariantCulture);
IModelBinder mb = new DefaultModelBinder();
return (T)mb.BindModel(new ControllerContext(), modelBindingContext);
}
}
请注意,有2种方法。它们仅在
request.Params
和request.QueryString
上有所不同。关于c# - 将QueryString解析为强类型对象,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/37703540/
