How to get a comma separated string from an array in C#?

 

In C#, you can easily convert an array of values into a comma-separated string by using the string.Join method. The string.Join method takes two parameters: the first parameter is the separator, in this case, a comma, and the second parameter is the array that you want to convert into a string.

Here's an example that demonstrates how to get a comma-separated string from an array in C#:

using System;

namespace ArrayToCommaSeparatedString

{

    class Program

    {

        static void Main(string[] args)

        {

            string[] fruits = new string[] { "apple", "banana", "cherry", "date" };

            string commaSeparatedFruits = string.Join(", ", fruits);

            Console.WriteLine("Comma Separated Fruits: " + commaSeparatedFruits);

        }

    }

}

In this example, we created an array of string values named fruits and assigned some values to it.

Next, we used the string.Join method to convert the fruits array into a comma-separated string. The string.Join method takes two parameters: the first parameter is the separator, in this case, a comma, and the second parameter is the fruits array. The string.Join method returns a string that we stored in the commaSeparatedFruits variable.

Finally, we used the Console.WriteLine method to print the comma-separated string on the console. The output of the program will show the comma-separated string of the fruits array.

In conclusion, converting an array of values into a comma-separated string in C# is a simple and straightforward task that can be achieved by using the string.Join method. All you need to do is to pass the separator, in this case, a comma, and the array that you want to convert into a string, and the string.Join method will take care of the rest.
