HeaderCollection.Contains(Header) method

Microsoft Office Live Communications Server 2005 with SP1


The Contains method determines whether the specific header exists in the collection.

[C#]public Boolean Contains(Headerh);
[Visual Basic .NET]Public Function Contains( _
  ByVal h As Header _
) As Boolean


  • h
    The Header object to search for within the collection.

Return Values

Returns true if the header exists in the collection; false if it does not.


Note that this method searches for a specific header object, not the header type. There may be multiple distinct headers within the collection that share the same header type; this method will return true only if an exact match (same header type, value, parameter list) is found.

The match is not case-sensitive.


Redistributable: Requires Microsoft Office Live Communications Server 2005 with SP1.
Namespace: Microsoft.Rtc.Sip
Assembly: ServerAgent (in ServerAgent.dll)
