c# - determine if a type/object is serialzable

In WCF, primitives type are serialzable, and some commonly used types are also serialzable, but some types are not serialzable , and when this types to be used in wcf as the data contract for message, then you might get into trouble.

there are ways to determine if a type is serializable or an instance is serializable. To check if a type (on the type object itself)

typeof(T).IsSerializable

 

or you can check on the instance 

private static bool IsSerializable(T obj)
{
    return ((obj is ISerializable) || (Attribute.IsDefined(typeof (T), typeof (SerializableAttribute))));
}

 

But be caereful that IsSerializable does not take into account the all types in the graph of objects being serialized for the serialable attribute.
