推荐答案

(From Employee As ClsEmployee In lstEmployee Where Employee.Gender = 1 Select _
     (From Children As clsChildren In Employee.Children Where Children.Gender = 1 _
            Select Children.Age).SingleOrDefault)

类似.Average和.Min命令将给出另外两个结果

similarly .Average and .Min commands will give the other two results
