There are many differences between Binary serialization and XML serialization. Some of them are given below:
| Binary serialization |
XML serialization |
| 1. In Binary serialization, all members are encoded in binary form. |
1. In XML serialization, all members are encoded in XML form that makes the code more readable. |
| 2. It provides better support as compared to XML serialization when storing data. |
2. It provides less support than Binary serialization when storing data. |
| 3. Binary serialization is used when we are using same application platform. |
3. XML serialization is used if we are using different application platform. |
| 4. It serialize all the fields of an object unless specified NonSerializable |
4. It serialize only the public fields and properties of an object. |
| 5.It serialize private members of a class which is called as deep serialization. |
5. It do not serialize the private members of a class which is called as shallow serialization. |
| 6.There is no easy control of each serialized member. |
6. There is easy control of each serialized member by using attributes. |
| 7. It saves metadata in output stream for deserialization. |
7. It does not save metadata in output stream for deserialization. |
| 8. There is no need of public constructor and public access. |
8. Class should have public constructor and public access. |
| 9.In binary serialization, there is no need to specify the type to be serialized or deserialized. |
9. In XMl serialization, we have to specify the type of object of type to be serialized or deserialized. |
| 10.Binary serialization preserves instance identity which mean entire object state is saved. |
10. XML serialization does not preserve instance identity because in XML serialization only some of the object data is saved. |
| 11. Binary serialization can handle graphs with multiple references to same object. |
11. XML serialization turn each reference into unique object. |
| 12.In Binary serialization, we use namespace called System.RunTime.Serialization.Formatters.Binary |
12. In XML serialization, we use namespace called System.Xml.Serialization |
| 13. Binary serialization is more efficient and faster than XML serialization. It saves memory and bandwidth and easier to parse than XML. |
13. XML serialization is less efficient and faster than Binary serialization. |
| 14. Binary Serializer need serializable attribute on the class. |
14. XML Serializer no need serializable attribute on the class. |
Example of Binary serialization:
//Adding namespace:
using System.Runtime.Serialization.Formatters.Binary;
using System.Runtime.Serialization;
public static void BinarySerialize(string filename, Object obj)
{
FileStream fileStreamObject;
fileStreamObject = new FileStream(filename, FileMode.Create, FileAccess.Write);
BinaryFormatter binaryFormatter = new BinaryFormatter();
try
{
binaryFormatter.Serialize(fileStreamObject, obj);
}
catch (SerializationException ex)
{
Console.WriteLine("Failed to serialize : " + ex.Message);
}
fileStreamObject.Close();
}
Example of XML serialization
//Adding namespace:
using System.Runtime.Serialization;
using System.Xml.Serialization;
public static void XMLSerialize(String filename, Object obj)
{
XmlSerializer serializer = null;
FileStream stream = null;
serializer = new XmlSerializer(typeof(Object));
stream = new FileStream(filename, FileMode.Create, FileAccess.Write);
try
{
serializer.Serialize(stream, obj);
}
catch (SerializationException ex)
{
Console.WriteLine("Failed to serialize : " + ex.Message);
}
if (stream != null)
stream.Close();
}
