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



How to Concatenate Strings in Array in C# ?

Answer

To concatenate strings in an array in C#, you can use the `string.Join` method or a loop to iterate through the array and concatenate each element.



✐ Examples

1 Concatenate Strings in Array with string.Join

In this example,

  1. We create an array `words` with strings.
  2. We use the `string.Join` method with the array to concatenate strings.
  3. We print the concatenated string.

C# Program

using System;

class Program
{
    static void Main()
    {
        string[] words = { "Hello", "World", "!" };
        string concatenated = string.Join(" ", words);
        Console.WriteLine("Concatenated String: " + concatenated);
    }
}

Output

Concatenated String: Hello World !

2 Concatenate Strings in Array with Loop

In this example,

  1. We create an array `words` with strings.
  2. We initialize an empty string `concatenated`.
  3. We use a foreach loop to iterate through the array and concatenate each element to `concatenated`.
  4. We print the concatenated string.

C# Program

using System;

class Program
{
    static void Main()
    {
        string[] words = { "Hello", "World", "!" };
        string concatenated = "";
        foreach (string word in words)
        {
            concatenated += word + " ";
        }
        Console.WriteLine("Concatenated String: " + concatenated.Trim());
    }
}

Output

Concatenated String: Hello World !
