I'm doing data involving arrays in C#, when I use the foreach loop it gave me an message

```
int[,] tel = new int[4, 8];
tel[0, 0] = 398;
tel[0, 1] = 3333;
tel[0, 2] = 2883;
tel[0, 3] = 17698;
tel[1, 0] = 1762;
tel[1, 1] = 176925;
tel[1, 2] = 398722;
tel[2, 0] = 38870;
tel[3, 1] = 30439;

foreach (string t in tel.ToString())
{
    Console.WriteLine(tel +" " +"is calling");
    Console.ReadKey();
}

```
