cannot convert type char to string

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

cannot convert type char to string 

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();
}

That is becuase when you foreach over a string each value will be a char, but you are trying to cast them to string.

 foreach(string t in tel.ToString())

But it's unlikely that you want to foreach on tel.ToString() as the will return the name of the type of tel (System.Int32[,]). Instead you probably want to iterate all the values in tel

for(int i=0; i<4; i++)
{
    for(int j=0; j<8; j++)
    {
        Console.WriteLine(tel[i,j] +" is calling");
        Console.ReadKey();
    }
}

Or

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

Note that some of the values will be zero since you do not assign values to all the positions in the tel array.

Iterate over the values in the array like this: 

int rowLength = tel.GetLength(0);
int colLength = tel.GetLength(1);

for (int i = 0; i < rowLength; i++)
{
    for (int j = 0; j < colLength; j++)
    {
        Console.WriteLine(tel[i, j]+" is calling");
    }
}
Console.ReadLine();
