C# DataGridView单元格不允许使用小数

private void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
{
    if (e.ColumnIndex == yourColumnIndex) // 替换为需要限制的列的索引
    {
        string input = e.FormattedValue.ToString();
        decimal value;
        if (!decimal.TryParse(input, out value) || value % 1 != 0)
        {
            e.Cancel = true; // 取消编辑
            dataGridView1.Rows[e.RowIndex].ErrorText = "只允许输入整数"; // 给出错误提示
        }
    }
}

private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
    dataGridView1.Rows[e.RowIndex].ErrorText = string.Empty;
}
