In this article, we would like to show you string Join() method example in C#.

Quick solution:

xxxxxxxxxx
 
string joinString = String.Join(" ", "Dirask", "is", "awesome", "!");
​
Console.WriteLine(joinString);
​
// Output:
// "Dirask is awesome !"

1. Documentation

Edit

Syntax	public static string Join(string separator, params obj[] array)
Parameters	separator- a sequence of characters that is used to separate each of the elements, params - the elements to join together.
Result	a new String that is composed of the elements separated by the separator
Description	The method returns a new String composed of copies of the params elements joined together with a copy of the specified separator.

2. Practical examples

Edit

C# string Join() method returns a string joined with a given separator which is copied for each element.

Example 1

Edit

In this example, we join string elements with an empty string as a separator.

xxxxxxxxxx
 
using System;
​
public class Program
{
    public static void Main()
    {
        string joinString = String.Join(" ", "Dirask", "is", "awesome", "!");
​
        Console.WriteLine(joinString);
    }
}

Output:

xxxxxxxxxx
 
Dirask is awesome !

Example 2

Edit

In this example, we use Join() method with - as a separator to display string elements as a date.

xxxxxxxxxx
 
using System;
​
public class Program
{
    public static void Main()
    {
        string joinString = String.Join("-", "2022", "02", "28");
​
        Console.WriteLine(joinString);
    }
}
