Я создаю игру Sudoku с ASP.NET и C#. Я должен использовать классы и наследование, чтобы полностью построить структуру на странице с кодом (т. Е. Элементы asp: TextBox на странице aspx отсутствуют).Очистка TextBoxes в C#
У меня ужасное время, пытаясь очистить входные данные, когда я начинаю новую игру. Я создаю новое решение для головоломок, но мои предыдущие ящики не ясны, и я пробовал все, что мог придумать.
Ниже приведены несколько фрагментов кода, которые относятся к проблеме.
код, который строит головоломки и сохраняет его в головоломку объекта.
private Puzzle newPuzzle(int[,] solution, int numbersVisible, int maxNumbersPerBox, int maxOccurancesPerNumber)
{
Puzzle newPuzzle = new Puzzle();
SudokuTextBox newTextbox;
Number newNumber;
Random randomRC = new Random();
//variable to hold the correct answer at the given location
int answer;
//variables to hold the location within the answers array
int rowLoc;
int colLoc;
//counter to count the number of times we while loop
int counter = 0;
//variables to hold the randomly-chosen rows & col values
int row;
int col;
//array to hold the positions of the numbers we are going to show
string[] show;
show = new string[numbersVisible];
while(counter < numbersVisible)
{
//generate random numbers that gives us the location of the numbers in the solution array that we are going to show
row = randomRC.Next(0, 9);
col = randomRC.Next(0, 9);
//if the random numbers are not already in the array
if (!show.Contains(row.ToString() + ":" + col.ToString()))
{
//add them to the array
show[counter] = row.ToString() + ":" + col.ToString();
//increase the counter
counter++;
} //end if...contains
} //end while
// BUILDING THE PUZZLE
//start looping through the puzzle rows
for (int pr = 0; pr < 3; pr++)
{
//another loop for puzzle columns
for (int pc = 0; pc < 3; pc++)
{
box = new Box(); //create a new Box object
//another loop for box rows
for (int br = 0; br < 3; br++)
{
//another loop for box columns
for (int bc = 0; bc < 3; bc++)
{
newTextbox = new SudokuTextBox();
newNumber = new Number();
//grab the answer to this particular SudokuTextBox from the solutions array
rowLoc = (pr + br + (2 * pr));
colLoc = (pc + bc + (2 * pc));
answer = solution[rowLoc, colLoc];
newNumber.setNumber(answer); //set the Number to the found answer
newTextbox.setTextBoxValue(newNumber); //fill in the textbox with Number
//if this SudokuTextBox is chosen to be given at the start of the puzzle
if (show.Contains((rowLoc + ":" + colLoc).ToString()))
{
//make this SudokuTextBox visible
newTextbox.setVisibility(true);
}
else {
newTextbox.setVisibility(false);
} //end if
box.setItem(newTextbox, br, bc); //add the SudokuTextBox to the correct position inside Box
} //end box column loop
} //end box row loop
newPuzzle.setItem(box, pr, pc); //add the Box to the correct position inside Puzzle
} //end puzzle column loop
} //end puzzle row loop
return newPuzzle;
} //end easy()
Сохранение новой головоломки в сессии:
//when the Easy button is pressed
protected void btnEasy_Click(object sender, EventArgs e)
{
//generate a new random number
Random newRandomSoln = new Random();
//keep picking new solutions until we get one that's different than the last one
do
{
solution = chooseSolution(newRandomSoln.Next(1, 11));
}
while (solution == Session["solution"]);
//store the new solution
Session["solution"] = solution;
//generate a new puzzle
Session["puzzle"] = newPuzzle((int[,])Session["solution"], 32, 4, 4);
}
код, который строит структуру таблицы, заполняет его ответы хранятся в головоломки, и добавляет его на страницу aspx:

Это ** много ** кода, но я не вижу код, который должен очистить предыдущую головоломку и сгенерировать новую. – CodingGorilla
Это может иметь хороший ответ: http://stackoverflow.com/questions/2613778/how-to-clear-all-form-fields-from-code-behind –
@CodingGorilla Я обновлю, чтобы показать этот код. – LakeJeffler
