public delegate bool Predicate<in T>(

Type Parameters

  • inInininT
    The type of the object to compare.

    This type parameter is contravariant. That is, you can use either the type you specified or any type that is less derived. For more information about covariance and contravariance, see [2678dc63-c7f9-4590-9ddc-0a4df684d42e].


  • obj
    Type: T
    The object to compare against the criteria.

Return Value

Type: System..::.Boolean
true if obj meets the criteria defined within the method represented by this delegate; otherwise, false.


None of the methods in the .NET Framework for Windows Phone class library have a Predicate<(Of <(T>)>) delegate as a parameter. The Predicate<(Of <(T>)>) delegate exists primarily to support the infrastructure, but you can still use it to create custom methods that use predicates.
