问题描述
我有以下datacontract：
I have the following datacontract:
[DataContract]
public class Occupant
{
private string _Name;
private string _Email;
private string _Organization;
private string _Badge;
public Occupant(string name, string badge, string organization)
{
Name = name;
Badge = badge;
Organization = organization;
}
public Occupant(string name, string badge)
{
Value = name;
Key = badge;
}
[DataMember]
public string Key
{
get { return _Name; }
set { _Name = value; }
}
[DataMember]
public string Value
{
get { return _Badge; }
set { _Badge = value; }
}
[DataMember]
public string Name
{
get { return _Name; }
set { _Name = value; }
}
[DataMember]
public string Email
{
get { return _Email; }
set { _Email = value; }
}
[DataMember]
public string Organization
{
get { return _Organization; }
set { _Organization = value; }
}
[DataMember]
public string Badge
{
get { return _Badge; }
set { _Badge = value; }
}
}
当我尝试通过Web浏览器访问该服务（其托管在IIS），我收到此错误：
When I try to access this service via web browser (it is hosted on IIS), I am getting this error:
System.Runtime.Serialization.InvalidDataContractException: Type 'MyNamespace.Occupant' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute.
我的一个方法返回一个列表类型乘员。这将是造成的呢？
One of my methods is returning a List of type Occupant. Would this be causing it?
推荐答案
由于您提供一个或多个构造函数初始化，你还需要增加一个无参数（缺省）构造函数。
Because you have provided one or more initializing constructors, you will also need to add a parameterless (default) constructor.
即。您需要添加：
[DataContract]
public class Occupant
{
// *** Needed only for Serialization
public Occupant() {}
...
这是因为default构造消失当您添加明确的构造函数。
This is because the default constructor disappears when you add an explicit constructor.
[问题不在于方法返回名单，其中，乘员GT; ，因为方法不序列化）]
[The issue isn't with the method returning List<Occupant>, since methods aren't serialized).]
