Parameters
- source
- Type: Sequences ISequence TSource
A sequence to filter.
- predicate
- Type: System Func TSource, Boolean
A function to test each element for a condition.
Type Parameters - TSource
- The type of the elements of source.
Return Value
Type:
ISequence TSource A sequence that contains elements from
source that satisfy the condition.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
ISequence TSource . When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
