LINQ ToList Method

In LINQ, the ToList operator takes the elements from the given source and returns a new List. So that means the input would be converted to type List.

Syntax of LINQ ToList() Operator

Following is the syntax of using LINQ ToList() to convert input collection to list.

LINQ ToList() Syntax in C#

List<string> result = countries.ToList();

LINQ ToList() Syntax in VB.NET 

Dim result As List(Of String) = countries.ToList()

If you observe above syntax we are converting “countries” collection to list using LINQ ToList() operator.

LINQ ToList() Operator in Method Syntax Example

Following is the example of using LINQ ToList() to convert input collection to a List in method syntax.

 

C# Code

 

using System;
using System.Collections.Generic;
using System.Linq;

namespace LINQExamples
{
  class Program
  {
   static void Main(string[] args)
   {
     string[] countries = { "US", "UK","India", "Russia", "China", "Australia", "Argentina" };
     List<string> result = countries.ToList();
     foreach (string s in result)
     {
       Console.WriteLine(s);
     }
     Console.ReadLine();
   }
  }
}

VB.NET Code

 

Module Module1
Sub Main()
Dim countries As String() = {"US", "UK", "India", "Russia", "China", "Australia", "Argentina"}
Dim result As List(Of String) = countries.ToList()
For Each s As String In result
Console.WriteLine(s)
Next
Console.ReadLine()
End Sub
End Module

If you observe the above example we are converting countries collection to List by using LINQ ToList () method.

LINQ ToList() in Query Syntax Example

Following is the example of using the LINQ ToList() operator in query syntax.

 

C# Code

 

using System;
using System.Collections.Generic;
using System.Linq;

namespace LINQExamples
{
  class Program
  {
    static void Main(string[] args)
    {
      string[] countries = { "US", "UK","India", "Russia", "China", "Australia", "Argentina" };
      List<string> result = (from x in countries select x).ToList();
      foreach (string s in result)
      {
        Console.WriteLine(s);
      }
      Console.ReadLine();
    }
  }
}

VB.NET

 

Module Module1
Sub Main()
Dim countries As String() = {"US", "UK", "India", "Russia", "China", "Australia", "Argentina"}
Dim result As List(Of String) = (From x In countries).ToList()
For Each s As String In result
Console.WriteLine(s)
Next
Console.ReadLine()
End Sub
End Module
