override this.System.Collections.Generic.ICollection<System.Collections.Generic.KeyValuePair<System.String,System.Object>>.Contains : System.Collections.Generic.KeyValuePair<string, obj> -> bool
Function Contains (pair As KeyValuePair(Of String, Object)) As Boolean Implements ICollection(Of KeyValuePair(Of String, Object)).Contains
