The 'foreach' Loop in C#

The 'foreach' Loop in C#:-

The C# 'foreach' keyword is used to iterate over all items within an array, without the need to test the upperbound of the array. See the below program,

class ForeachLoop
{

static void Main(string[] args)
{

//itterate string array

string[] name ={"DotNetSpark","Join it NOW!!"};

foreach(string s in name)

Console.WritwLine(s);

//itterating integer array

int[] value={12,23,34,45,56};

foreach(int i in values)

Console.WriteLine(i);

}

}

The above program will traverse the string and integer array. The 'foreach' loop can also be used to itterate over system-supplied or user-defined collections. The 'foreach' loop in C# is used to retrive the values, that means it is used for receiving values, we can't enter values using 'foreach'.
