Parallel.For无法continue怎么办

 Parallel.For(0, r1.LastCol, (i, loopState) =>

            {                var item = myType.GetProperty(r1.getText(0, i));

                if (item == null)

                {

                    loopState.Break();

                }

  if (item.Name.Contains("比例"))

                    {

item == null时还是会运行到item.Name.Contains.结果出错了
------解决方案--------------------
 Parallel.For(0, r1.LastCol, (i, loopState) =>
            {                var item = myType.GetProperty(r1.getText(0, i));
                if (item == null)
                {
                    loopState.Stop();
                    break;
                }
  if (item.Name.Contains("比例"))
                    {

------解决方案--------------------
把loopState.Break();换成return;
------解决方案--------------------

Parallel.For(0, r1.LastCol, (i, loopState) =>

            {                var item = myType.GetProperty(r1.getText(0, i));

                if (item == null)

                {

                    loopState.Stop();

                    return; //写错了 - -!
