C#ISerializable问题

Unless you mark the class with the
[Serializable] attribute,this
interface must be implemented by all
classes with serialized instances. Use
the ISerializable interface if you
want your class to control its own
serialization and de-serialization.

GetObjectData()允许您控制序列化过程.

GetDataObject,to which you pass a
SerializationInfo object and a
StreamingContext object. The
GetDataObject method will then
populate the SerializationInfo object
with the data necessary for the
serialization of the target object.

例：

public Employee(SerializationInfo info,StreamingContext ctxt)
{
    //Get the values from info and assign them to the appropriate properties
    EmpId = (int)info.GetValue("EmployeeId",typeof(int));
    EmpName = (String)info.GetValue("EmployeeName",typeof(string));
}

public void GetObjectData(SerializationInfo info,StreamingContext ctxt)
{
    //You can use any custom name for your name-value pair. But make sure you
    // read the values with the same name. For ex:- If you write EmpId as "EmployeeId"
    // then you should read the same with "EmployeeId"
    info.AddValue("EmployeeId",EmpId);
    info.AddValue("EmployeeName",EmpName);
}

上面的示例显示了如何反序列化和序列化.如您所见,反序列化需要GetObjectData.如果将其留空,则您的对象将没有所需的值.
