Set a whole Board at once

Use a string

using DE.Onnen.Sudoku;
using DE.Onnen.Sudoku.Extensions;

// Create Sudoku-Board
var board = new Board();

// Load a whole board from string
board.SetCellsFromString("100000000000000000000000000000000000000000000000000000000000000000000000000000009");
Console.WriteLine($"Digit of Cell0 (first Cell): {board.First().Digit}");
Console.WriteLine($"Digit of Cell80 (last Cell): {board.Last().Digit}");

Output

Digit of Cell0 (first Cell): 1
Digit of Cell80 (last Cell): 9
