在if条件下如何写有效期问题

Question

此代码在数量减少时会更改行颜色，但是现在我需要用它来解决这样的到期问题

private void DgvStock_CellFormatting_1(object sender, DataGridViewCellFormattingEventArgs e)
{
    foreach (DataGridViewRow row in DgvStock.Rows)
    {
        int Qty = Convert.ToInt32(row.Cells[4].Value);
        if (Qty <= 10)
        {
            row.DefaultCellStyle.ForeColor = Color.White;
            row.DefaultCellStyle.BackColor = Color.Red;
        }
    }
}

您的问题尚不清楚，但是据我了解，请检查下面的代码是否对您有帮助。

private void DgvStock_CellFormatting_1(object sender, DataGridViewCellFormattingEventArgs e)
{
    foreach (DataGridViewRow row in DgvStock.Rows)
    {
        int Qty = Convert.ToInt32(row.Cells[4].Value);
        if (Qty <= 10)
        {
            row.DefaultCellStyle.ForeColor = Color.White;
            row.DefaultCellStyle.BackColor = Color.Red;
        }

DateTime exp = Convert.ToDateTime(row.Cells["yourExpiryDateColumn"].Value);
        if (exp <= System.DateTime.Now.AddDays(-90))//Updated -90 days
        {
            row.DefaultCellStyle.ForeColor = Color.White;
            row.DefaultCellStyle.BackColor = Color.Red;
        }
    }
}
