Equality in LINQ
Compares two sentences (enumerable ) and determine are they an exact match or not.
Operator | Description | C# Query Expression Syntax | VB Query Expression Syntax |
---|---|---|---|
SequenceEqual | Results a Boolean value if two sequences are found to be identical to each other | Not Applicable | Not Applicable |
Example of SequenceEqual - Enumerable.SequenceEqual Method
C#
using System; using System.Collections.Generic; using System.Linq; namespace Operators { class SequenceEqual { static void Main(string[] args) { Pet barley = new Pet() { Name = "Barley", Age = 4 }; Pet boots = new Pet() { Name = "Boots", Age = 1 }; Pet whiskers = new Pet() { Name = "Whiskers", Age = 6 }; List<Pet> pets1 = new List<Pet>() { barley, boots }; List<Pet> pets2 = new List<Pet>() { barley, boots }; List<Pet> pets3 = new List<Pet>() { barley, boots, whiskers }; bool equal = pets1.SequenceEqual(pets2); bool equal3 = pets1.SequenceEqual(pets3); Console.WriteLine("The lists pets1 and pets2 {0} equal.", equal ? "are" :"are not"); Console.WriteLine("The lists pets1 and pets3 {0} equal.", equal3 ? "are" :"are not"); Console.WriteLine("\nPress any key to continue."); Console.ReadKey(); } class Pet { public string Name { get; set; } public int Age { get; set; } } } }
VB
Module Module1 Sub Main() Dim barley As New Pet With {.Name = "Barley", .Age = 4} Dim boots As New Pet With {.Name = "Boots", .Age = 1} Dim whiskers As New Pet With {.Name = "Whiskers", .Age = 6} Dim pets1 As New System.Collections.Generic.List(Of Pet)(New Pet() {barley, boots}) Dim pets2 As New System.Collections.Generic.List(Of Pet)(New Pet() {barley, boots}) Dim pets3 As New System.Collections.Generic.List(Of Pet)(New Pet() {barley, boots, whiskers}) Dim equal As Boolean = pets1.SequenceEqual(pets2) Dim equal3 As Boolean = pets1.SequenceEqual(pets3) Console.WriteLine("The lists pets1 and pets2 {0} equal.", IIf(equal, "are", "are not")) Console.WriteLine("The lists pets1 and pets3 {0} equal.", IIf(equal3, "are", "are not")) Console.WriteLine(vbLf & "Press any key to continue.") Console.ReadKey() End Sub Class Pet Public Property Name As String Public Property Age As Integer End Class End Module
When the above code of C# or VB is compiled and executed, it produces the following result −
The lists pets1 and pets2 are equal. The lists pets1 and pets3 are not equal. Press any key to continue.
