AsyncQueryable.Sum Method (IAsyncQueryable<Single>, CancellationToken)

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

Parameters

source
Type: System.Linq.IAsyncQueryable<Single>
cancellationToken
Type: System.Threading.CancellationToken

Return Value

Type: Task<Single>

Usage Note

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