  8. List<SudokuCell> GetCellsInRow(int row)
  9. List<SudokuCell> GetCellsInColumn(int column)
  10. void Print(bool HideLevelValues = false)

Usage

To generate a valid sudoku

SudokuGrid sudokuGrid = SudokuGenerator.Generate(9, SudokuGrid.LevelDifficulty.Easy);

To get generated sudoku values

List<SudokuGrid.SudokuCell> sudokuCells = sudokuGrid.GetSudokuCells();

To get values on a sector

List<SudokuGrid.SudokuCell> cellsInSector = sudokuGrid.GetCellsInSector(0);

To get value from a point

SudokuGrid.SudokuCell cellAtPoint = sudokuGrid.GetCellAtPoint(0, 1);

To get value at index

SudokuGrid.SudokuCell cellAtIndex = sudokuGrid.GetCellAtIndex(0);

To get values from column

List<SudokuGrid.SudokuCell> cellsInColumn = sudokuGrid.GetCellsInColumn(0);

To get values from row

List<SudokuGrid.SudokuCell> cellsInRow = sudokuGrid.GetCellsInRow(0);

To get grid size

int gridSize = sudokuGrid.GetGridSize();

To get number of sectors

int numberOfSectors = sudokuGrid.GetNumberOfSectors();

Print generated values to output window of Visual Studio

sudokuGrid.Print();
