How to Convert an Array of Strings to an Array of Integers in C# ?

Answer

To convert an array of strings to an array of integers in C#, you can use LINQ with the `Select` function and parse each string element into an integer.

✐ Examples

1 Convert Strings to Integers

In this example,

We have an array of strings named strArray containing string representations of integers.
We use LINQ with the Select function to transform each element of strArray to an integer using int.Parse.
The resulting array intArray contains the converted integers.
We print the contents of intArray to demonstrate the conversion.

C# Program

using System;
using System.Linq;
class Program
{
    static void Main()
    {
        string[] strArray = {"10", "20", "30"};
        int[] intArray = strArray.Select(int.Parse).ToArray();
        Console.WriteLine("Converted array of integers: " + string.Join(", ", intArray));
    }
}

Output

Converted array of integers: 10, 20, 30
