C# String Array Examples

C# String Array

1.  Declaring string arrays

~~~ Program that initializes string arrays (C#) ~~

class Program

{

static void Main()

{

// String arrays with 3 elements:

string[] arr1 = new string[] { "one", "two", "three" }; // 1

string[] arr2 = { "one", "two", "three" }; // 2

var arr3 = new string[] { "one", "two", "three" }; // 3

string[] arr4 = new string[3]; // 4

arr4[0] = "one";

arr4[1] = "two";

arr4[2] = "three";

}

}

Output of the program

 (Four string arrays are initialized.)

2.  String arrays at class level

class Program

{

static void Main()

{

Test test = new Test(); // Create new instance with string array

foreach (string element in test.Elements)

// Loop over elements with property

{

System.Console.WriteLine(element);

}

System.Console.WriteLine(test[0]); // Get first string element

}

}

public class Test

{

/// String array field instance.
string[] _elements = { "one", "two", "three" };

/// String array property getter.
public string[] Elements

{

get { return _elements; }

}

/// String array indexer.
public string this[int  index]

{

get { return _elements[index]; }

}

}

Output of the program

one

two

three

one
