Linq 查找维数最大的数

[倒大霉的上帝]

我现在有这样一个数组，
string[][] str = {new string[]{"a","b","c"},new string[]{"aa","bb","cc","dd","ee"},new string[] {"aaa","bbb"} };
怎样用LinQ查找维数最大的值？
这里范围的应该是 5 也就是 str[1].Length

[EnForGrass]

  string[][] strarray = { new string[] { "a", "b", "c" }, new string[] { "aa", "bb", "cc", "dd", "ee" }, new string[] { "aaa", "bbb" } };
 int maxwei = (from p in strarray.AsEnumerable()
                          select p.Length).Max();
