试试这个
C# code
int one = 0;
int zero = 0;

bool flag = true;
int tc = 0;
Action action = () => { if (flag) { if (tc > one) { one = tc; } } else { if (tc > zero) { zero = tc; } } };
for (int i = 0; i < Grid.Rows.Count; i++)
{
    if ((Grid[0, i] != null) != flag)
    {
        action();
        tc = 0;
        flag = !flag;
    }
    ++tc;
}
action();
