How to Concatenate Strings in List in C# - Step by Step Examples

How to Concatenate Strings in List in C# ?

Answer

To concatenate strings in a list in C# using `System.Collections.Generic.List`, you can use the `string.Join` method.


✐ Examples

1 Concatenate Strings in List Using string.Join

In this example,

  1. We include the necessary namespace for using System.Collections.Generic.
  2. We create a List named words with some strings.
  3. We use the string.Join method to concatenate the strings in the list with a specified separator.
  4. Finally, we print the concatenated string to standard output.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<string> words = new List<string> { "Hello", "World", "!" };
        string concatenated = string.Join(" ", words);
        Console.WriteLine("Concatenated string: " + concatenated);
    }
}

Output

Concatenated string: Hello World !

2 Concatenate Strings in Another List Using string.Join

In this example,

  1. We include the necessary namespace for using System.Collections.Generic.
  2. We create another List named phrases with different strings.
  3. We use the string.Join method to concatenate the strings in this list with a specified separator.
  4. Finally, we print the concatenated string to standard output.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<string> phrases = new List<string> { "Good", "morning", "everyone" };
        string concatenated = string.Join(", ", phrases);
        Console.WriteLine("Concatenated string: " + concatenated);
    }
}

Output

Concatenated string: Good, morning, everyone
