AsyncEnumerableSum Method (IAsyncEnumerableNullableDecimal, CancellationToken)

Namespace: System.Linq
Assembly: System.Interactive.Async (in System.Interactive.Async.dll) Version: 1.2.0.0
Syntax
C#
Copy
public static Task<Nullable<decimal>> Sum(
	this IAsyncEnumerable<Nullable<decimal>> source,
	CancellationToken cancellationToken
)

Parameters

source
Type: System.Collections.GenericIAsyncEnumerableNullableDecimal

Return Value

Type: TaskNullableDecimal

Usage Note

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