Serialization is the process of converting an object to transferable data format. By default WCF uses DataContractSerializer. And vice-versa process is called De-Serialization.
public class Product { public int ProductID { get;set; } public string ProductName { get;set; } public string ProductSeller { get;set; } public decimal ProductCost { get;set; } } |
Browse the service and open WSDL file.
Notice a namespace containing datacontract
Open the URL highlighted below.
You may notice the details that I added in Product class.
After adding Serializable attribute:
[Serializable]
public class Product
{ }
Now you may notice the change in xml file. Serializable attribute serialize all private properties.
Now if you want a control over serialization. Means you don’t want all data to send to client only few of the you want to exchange.
Use DataContract and DataMember attribute
[DataContract] public class Product { [DataMember] public int ProductID { get;set; } [DataMember] public string ProductName { get;set; } public string ProductSeller { get;set; } public decimal ProductCost { get;set; } } |
In below code, i have added DataMemeber attribute with ProductID and ProductName
Let’s see the WSDL file.
You may notice only ProductID and ProductName is showing below why because I have used DataMember attribute with these two.
Summary:
- If we use Serialize attribute then we will not have any control over fields. All fields will be serialize.
- If we use DataContract attribute then we can control the fields by adding DataMember attribute if we want to serialize else with no attribute.
