Syntax

Copy

public static IAsyncQueryable<IAsyncGrouping<TKey, TSource>> GroupBy<TSource, TKey>(
	this IAsyncQueryable<TSource> source,
	Expression<Func<TSource, TKey>> keySelector
)

Parameters

source: Type: System.Linq.IAsyncQueryable<TSource>
keySelector: Type: System.Linq.Expressions.Expression<Func<TSource, TKey>>

Type Parameters

TSource
TKey

Return Value

Type: IAsyncQueryable<IAsyncGrouping<TKey, TSource>>

Usage Note

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