MVC复杂类型的模型绑定

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){}
}
