Datamember null

You should set the EmitDefaultValue property to false if there is a specific need to do so, such as for interoperability or data size reduction. The following code has several members with the EmitDefaultValue set to false. If an instance of this class is serialized, the result is as follows: employeeName and employeeID is serialized. The null value for employeeName and the zero value for employeeID is explicitly part of the serialized data.

However, the position , salary , and bonus members are not serialized. Finally, targetSalary is serialized as usual, even though the EmitDefaultValue property is set to false , because does not match the. NET default value for an integer, which is zero. Note that there is no information at all in the XML about position, salary, and bonus data members.

The receiving end can interpret these as null , zero, and null , respectively. There is no guarantee that a third-party deserializer can make the correct interpretation, which is why this pattern is not recommended.

You can define Data Members by just placing [DataMemeber] attribute on the property or the field. In the example given above, IsRequired true parametervalue of ID Data Member tells the serialization engine that it is required and Fees is not required. This parameter is used to get or set the name of the data member.

The default value of this parameter is the name of the property or the field on which it is applied. I am having a problem serializing null value.

What is your serializer? Put [DataIgrore] attribute on the property you don't want to serialize — George Findulov. It is conditional. OP wants to ignore if property is null! GeorgeFindulov — Hamid Pourjam. Add a comment. Active Oldest Votes. It would still succeed, and the operation would receive a MyDC object with the field "str" with the default value for string null.

However, if this request was sent:. Then the request would fail - because the data contract MyDC requires that the member "i" is present on the wire. If you want validation done at the client side, however, you'll going to need to add code to the client code for that. Another thing you'll have to keep in mind is the definition of "not present". Given that you have an object of type MyDC as defined above , what does it mean for it not to have the field "i" present? On the definition above I didn't set any value, but the CLR will set it to zero default for integer automatically.

This does is requires the Wcf runtime to serialize data member but do not serialize default values, i. In effect, a runtime exception will be thrown if the data member has not been assign a value during serialization.

Error :. The value '' cannot be parsed as the type 'Boolean'. Please see InnerException for more details. Any Help would really appriciated. Client is using some middlware to form this request and hence we get the request only in the form mentioned below.
