[英](C#) DataGridView: How to get Selected Count with cells AND rows?
[英]datagridview count cells c#
我有個問題。 我需要計算激活的細胞,它們是黃色的,但我不知道該怎么做。 在geniral中,我只需要選擇最多15個單元格,因此我需要對它們進行計數,但是我的所有嘗試似乎都還很遙遠。 我試圖建立一個櫃台,但是沒有用。 請幫忙。
dataGridView1.SelectionMode = DataGridViewSelectionMode.CellSelect;
//выделение только ячеек
// создаём массив
int[,] Array = new int[8, 10];
byte numbers = 1;
for (int i = 0; i < 8; i++)
{
for (int j = 0; j < 10; j++)
{
Array[i, j] = numbers;
numbers++;
}
}
dataGridView1.RowCount = 8;
dataGridView1.ColumnCount = 10;
// программно записываем массив и задаём стиль ячеек
for (int i = 0; i < 8; i++)
{
for (int j = 0; j < 10; j++)
{
dataGridView1.Columns[j].Width = 30;
dataGridView1.Rows[i].Height = 30;
dataGridView1.Rows[i].Cells[j].Style.Alignment = DataGridViewContentAlignment.MiddleCenter;
dataGridView1.Rows[i].Cells[j].Style.Font = new Font(FontFamily.GenericSansSerif, 10, FontStyle.Bold);
dataGridView1.Rows[i].Cells[j].Value = Array[i, j].ToString();
}
}
}
private void dataGridView1_CellMouseUp(object sender, DataGridViewCellMouseEventArgs e) // выделение ячеек
{
for (int i = 0; i < dataGridView1.SelectedCells.Count; i++)
{
if (dataGridView1.SelectedCells[i].Style.BackColor == Color.Yellow)
{
dataGridView1.SelectedCells[i].Style.BackColor = Color.White;
}
else
{
dataGridView1.SelectedCells[i].Style.BackColor = Color.Yellow;
}
dataGridView1.CurrentCell = null;
}
}
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
byte _selected = 0;
for (int i = 0; i < dataGridView1.SelectedCells.Count; i++)
{
counter(_selected);
}
}
public void counter(int count)
{
count++;enter code here
MessageBox.Show(count.ToString());
}
這是表格的外觀。 形成
游戲的名稱是基諾,我嘗試創建它。 抱歉,我可能有一些錯誤。
您可以使用此鏈接來計算單元格,但可以將其他組件或WPF用於此游戲。

這是我對您的代碼的看法。 在此代碼段中,我將使用int yellowed
來跟蹤多少個單元格為黃色。 用戶clicks
單元格時,單元格計數器會設置黃色計數。 當鼠標按鈕向上( dataGridView1_CellMouseUp
)時,僅允許將適當數量的單元格設置為黃色。
