隐藏与标签c＃不匹配的所有行

Question

我想隐藏datagridview中与Access.text标签中的文本不匹配的所有行，我将如何实现此目的？该代码在程序运行时隐藏所有行

    private void Access_TextChanged(object sender, EventArgs e)
    {
        BindingContext[productionBindingSource].SuspendBinding();
        foreach (DataGridViewRow row in this.productionDGV.Rows)
        {
            if (row.Cells[4].Value.ToString() != Access.Text)
            {
                row.Visible = false;
            }
        }
        BindingContext[productionBindingSource].ResumeBinding();
    }
