Enumerable::SequenceEqual<TSource> Method (IEnumerable<TSource>, IEnumerable<TSource>, IEqualityComparer<TSource>)
Determines whether two sequences are equal by comparing their elements by using a specified IEqualityComparer<T>.
Assembly: System.Core (in System.Core.dll)
[ExtensionAttribute] public: generic<typename TSource> static bool SequenceEqual( IEnumerable<TSource>^ first, IEnumerable<TSource>^ second, IEqualityComparer<TSource>^ comparer )
The type of the elements of the input sequences.
- Type: System.Collections.Generic::IEnumerable<>
An IEnumerable<T> to compare to the first sequence.
Return ValueType: System::Boolean
true if the two source sequences are of equal length and their corresponding elements compare equal according to comparer; otherwise, false.
Usage NoteIn Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable<>. 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).
The following example shows how to implement an equality comparer that can be used in the method.
After you implement this comparer, you can use sequences of Product objects in the method, as shown in the following example.
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
