1,属性为引用类型(非集合,非数组)
//模型1 public class Contact { public string Name { get; set; } public string PhoneNo { get; set; } public string EmailAddress { get; set; } public Address MyAddress { get; set; } } public class Address { public string Province { get; set; } public string City { get; set; } public string District { get; set; } public string Street { get; set; } }
//请求表单范例,name属性,具有显著的层次结构,注意子属性前缀用的是属性名MyAddress <input name="Name" type="text" ... /> <input name="PhoneNo" type="text" ... /> <input name="EmailAddress" type="text" ... /> <input name="MyAddress.Province" type="text" ... /> <input name="MyAddress.City" type="text" ... /> <input name="MyAddress.District" type="text" ... /> <input name="MyAddress.Street" type="text"... />
public ActionResult Action(Contact foo){}
2,基于名称的简单类型数组绑定(名称必须相同)
//数据源范例 <input name="Foo" type="text" value="123"/> <input name="Foo" type="text" value="456" /> <input name="Foo" type="text" value="789" />
Public ActionResult ActionMethod(string[] foo){}//action的参数名“foo”,必须与表单中的name的值匹配
3,基于索引的对象数组绑定(索引必须从0开始,且连续,不连续会导致后面的绑定丢失)
//请求表单范例 <input name="[0].Name" type="text" value="" .../>
<input name="[0].PhoneNo" type="text" ... /> <input name="[0].EmailAddress" type="text" ... />
<input name="[1].Name" type="text" value="" .../>
<input name="[1].PhoneNo" type="text" ... /> <input name="[1].EmailAddress" type="text" ... />
public ActionResult Index(Contact[] contacts){}
4,集合(除数组和字典之外的所有实现IEnumerable<T>接口的类型)
//请求表单范例 <input name="[0].Name" type="text" value="" .../> <input name="[0].PhoneNo" type="text" value="" .../> <input name="[0].EmailAddress" type="text" value="" .../> <input name="[1].Name" type="text" value="" .../> <input name="[1].PhoneNo" type="text" value="" .../> <input name="[1].EmailAddress" type="text" value="" .../>
//集合范例 public ActionResult Action(IEnumerable<Contact> contacts){
foreach (var contact in contacts){}
}
5,字典(实现了接口IDictionary<TKey,TValue>的类型)
//请求表单范例,注意Key的值不能重复,且索引要连续 <input name="[0].Key" type="text" value="Foo" .../> <input name="[0].Value.Name" type="text" value="" .../> <input name="[0].Value.PhoneNo" type="text" value="139" .../> <input name="[0].Value.EmailAddress" type="text" value="a@z.com" .../> <input name="[1].Key" type="text" value="Bar" .../> <input name="[1].Value.Name" type="text" value="Bar" .../> <input name="[1].Value.PhoneNo" type="text" value="138" .../> <input name="[1].Value.EmailAddress" type="text" value="b@z.com" .../>
public ActionResult Action(IDictionary<string, Contact> contacts) { foreach (string key in contacts.Keys) { Contact contact = contacts[key]; } }
6,混合应用,属性是数组
public class QuizAnswer { public int QuizId { get; set; } public string[] QuizAnswerArray { get; set; }//答案为数组 }
<!--第一题,单选--> <input name="[0].QuizId" type="hidden" value="101" /> <input name="[0].QuizAnswerArray" type="radiobox" value="A" /> <input name="[0].QuizAnswerArray" type="radiobox" value="B" /> <input name="[0].QuizAnswerArray" type="radiobox" value="C" /> <input name="[0].QuizAnswerArray" type="radiobox" value="D" /> <!--第二题,多选--> <input name="[1].QuizId" type="hidden" value="102" /> <input name="[1].QuizAnswerArray" type="checkbox" value="A" /> <input name="[1].QuizAnswerArray" type="checkbox" value="B" /> <input name="[1].QuizAnswerArray" type="checkbox" value="C" /> <input name="[1].QuizAnswerArray" type="checkbox" value="D" />
//控制器代码 public ActionResult SubmitAnswer(QuizAnswer[] answerArray) { foreach (var answer in answerArray) { } }
7,混合应用,属性是集合
模型:属性是集合的情况
//公司 public class Company { public string Name { get; set; } public string City { get; set; } public IList<Job> JobList{ get; set; }//这里是个集合 } //职位 public class Job { public string Title{ get; set; } public string Detail{ get; set; } }
//注意集合的前缀为List <input name="Name" type="text" ... /> <input name="City" type="text" ... /> <input name="JobList[0].Title" type="text" ... /> <input name="JobList[0].Detail" type="text" ... /> <input name="JobList[1].Title" type="text" ... /> <input name="JobList[1].Detail" type="text" ... /> <input name="JobList[2].Title" type="text" ... /> <input name="JobList[2].Detail" type="text" ... />
//controller Public ActionResult ActionMethod(Company company) { foreach(var job in company.JobList){} }
