Assembly: System.Core (in System.Core.dll)
The type of the elements of source.
- Type: System.Linq.IQueryable()
The sequence to return elements from.
- Type: System.Int32
The number of elements to return.
Return ValueType: System.Linq.IQueryable()
An IQueryable(T) that contains the specified number of elements from the start of source.
Usage NoteIn Visual Basic and C#, you can call this method as an instance method on any object of type IQueryable(). 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).
source is a null reference (Nothing in Visual Basic).
The method generates a MethodCallExpression that represents calling itself as a constructed generic method. It then passes the MethodCallExpression to the CreateQuery(Expression) method of the IQueryProvider represented by the Provider property of the source parameter.
The query behavior that occurs as a result of executing an expression tree that represents calling depends on the implementation of the type of the source parameter. The expected behavior is that it takes the first count elements from the start of source.
