Syntax

'Declaration
Public Function FindHeader ( _
    name As String, _
    ns As String _
) As AddressHeader

public AddressHeader FindHeader(
    string name,
    string ns
)

Parameters

  • name
    Type: System.String
    The name of the address header to be found.
  • ns
    Type: System.String
    The namespace of the address header to be found.

Return Value

Type: System.ServiceModel.Channels.AddressHeader
The AddressHeader in the collection with the specified name and namespace.

Exceptions

Exception Condition
ArgumentNullException

name or ns is nulla null reference (Nothing in Visual Basic).
ArgumentException

There is more than one header that has the specified name and ns.

Remarks

If you need to find all the address headers in the collection with the specified name and namespace, use the FindAll(String, String) method instead.

ArgumentException is not the ideal exception type when there is more than one header in the collection. Callers of this method should take care to handle this exception when the collection contains multiple entries with the same name and namespace.
