dotnet loop over array code example

Example 1: loop through string array c#

string[] arr = new string[4]; // Initialize.
        arr[0] = "one";               // Element 1.
        arr[1] = "two";               // Element 2.
        arr[2] = "three";             // Element 3.
        arr[3] = "four";              // Element 4.

        // Loop over strings.
        foreach (string s in arr)
        {
            Console.WriteLine(s);
        }

Example 2: c# loop though array

int[,] numbers2D = new int[3, 2] { { 9, 99 }, { 3, 33 }, { 5, 55 } };
// Or use the short form:
// int[,] numbers2D = { { 9, 99 }, { 3, 33 }, { 5, 55 } };

foreach (int i in numbers2D)
{
    System.Console.Write("{0} ", i);
}
// Output: 9 99 3 33 5 55
