Return Value

Type: System.Boolean
true if the reader is at the start element of the stream to read; otherwise, false.


The IsStartObject determines whether it can read an object by checking that it is positioned on an XML element. It also examines the name and namespace of the XML element that the reader is positioned at and compares the values to the expected name and namespace. The expected name and namespace can be set with one of the following:

  • The data contract name and namespace of the type passed into the constructor.

  • The rootName and rootNamespace values passed into the constructor (if present).
