c＃Parallel For Loop多线程

Question

我试图将数据绑定到复制源数据表的多个gridview控件。不幸的是，这需要很长时间才能加载页面和执行代码。我尝试使用paralle for循环但我的代码中有变量，这不起作用。有没有人知道如何使用Parallel for循环与变量或任何其他方式加快这一点？在此先感谢您的帮助！

private void DeleteRows(DataTable dt)
    {
        string[] arrayHUB = new string[8];
        arrayHUB[0] = "SYS";
        arrayHUB[1] = "DFW";
        arrayHUB[2] = "DCA";
        arrayHUB[3] = "ORD";
        arrayHUB[4] = "JFK";
        arrayHUB[5] = "DEN";
        arrayHUB[6] = "PIT";
        arrayHUB[7] = "LAX";

        Parallel.For(0, arrayHUB.Length,
               index =>
               {
                   for (int i = 0; i < arrayHUB.Count(); i++)
                   {
                       string HUB = arrayHUB[i];

                       if (HUB == "SYS")
