我已经调查了IComparable属性的二进制序列化问题，当IComparable属性被分配了DateTime时会导致以下错误：
二进制流'0'不包含有效的BinaryHeader。
以下代码可能会产生此问题：
/// <summary>
/// This class is injected with an icomparable object, which is assigned to a property.
/// If serialized then deserializes using binary serialization, an exception is thrown
/// </summary>
[Serializable]
public class SomeClassNotWorking
{
public SomeClassNotWorking(IComparable property)
{
Property = property;
}
public IComparable Property;
}
public class Program
{
static void Main(string[] args)
{
// var comparable = new SomeClass<DateTime>(DateTime.Today);
// here we pass in a datetime type that inherits IComparable (ISerializable also produces the error!!)
var instance = new SomeClassNotWorking(DateTime.Today);
// now we serialize
var bytes = BinaryHelper.Serialize(instance);
BinaryHelper.WriteToFile("serialisedResults", bytes);
// then deserialize
var readBytes = BinaryHelper.ReadFromFile("serialisedResults");
var obj = BinaryHelper.Deserialize(readBytes);
}
}
我已经通过将IComparable属性替换为实现IComparable的类型T属性来解决了这个问题：
/// <summary>
/// This class contains a generic type property which implements IComparable
/// This serializes and deserializes correctly without error
/// </summary>
/// <typeparam name="T"></typeparam>
[Serializable]
public class SomeClass<T> where T : IComparable
{
public SomeClass(T property)
{
Property = property;
}
public T Property;
}
此序列化和反序列化没有问题。但是，为什么IComparable属性的序列化（当该属性是DateTime时）会导致问题，特别是当DateTime支持IComparable时？ ISerializable也会发生这种情况。
