You can print the 2D array like this:

for (int i = 0; i < array_1.GetLength(0); i  )
{
    // unconditionally start every line with a {
    Console.Write("{");    
    // print comma separated except the last element
    for (int j = 0; j < array_1.GetLength(1)-1; j  )
    {
        Console.Write(array_1[i, j]);
        Console.Write(", ");
    }
    // last element
    Console.Write(array_1[i, array_1.GetLength(1)-1]);
    // unconditionally end every line with a }
    Console.WriteLine("}");  
}
