How to check if an object is serializable in C#

Question

I am looking for an easy way to check if an object in C# is serializable.

As we know you make an object serializable by either implementing the ISerializable

Answer 1

This is an old question, that may need to be updated for .NET 3.5+. Type.IsSerializable can actually return false if the class uses the DataContract attribute. Here is a snippet i use, if it stinks, let me know :)

public static bool IsSerializable(this object obj)
{
    Type t = obj.GetType();

     return  Attribute.IsDefined(t, typeof(DataContractAttribute)) || t.IsSerializable || (obj is IXmlSerializable)

}
