Parameters

source

Type: System.Collections.GenericIEnumerableTSource
Source sequence.

Type Parameters

TSource

Source sequence element type.

Return Value

Type: IBufferTSource
Buffer enabling each enumerator to retrieve elements from the shared source sequence.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerableTSource. 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).

var rng = Enumerable.Range(0, 10).Share(); var e1 = rng.GetEnumerator(); // Both e1 and e2 will consume elements from var e2 = rng.GetEnumerator(); // the source sequence. Assert.IsTrue(e1.MoveNext()); Assert.AreEqual(0, e1.Current); Assert.IsTrue(e1.MoveNext()); Assert.AreEqual(1, e1.Current); Assert.IsTrue(e2.MoveNext()); // e2 "steals" element 2 Assert.AreEqual(2, e2.Current); Assert.IsTrue(e1.MoveNext()); // e1 can't see element 2 Assert.AreEqual(3, e1.Current);
