VB.NET入门 ANDALSO 和OrElse 之于 AND，OR

Module Module1

Sub Main()
Dim x As Integer = 8, y As Integer = 5, z As Integer = 3
Console.WriteLine(“x={0},y={1},z={2}”, x, y, z)
Console.WriteLine(“x>y ANDALSO y>z={0}”, x > y AndAlso y > z)
Console.WriteLine(“y>x ANDALSO Y>Z={0}”, y > x AndAlso y > z)
Console.WriteLine(“X> ANDALSO Z>Y={0}”, x > y AndAlso z > y)
Console.WriteLine(“x>y ORELSE y>z={0}”, x > y OrElse y > z)
Console.WriteLine(“y>x ORELSE Y>Z={0}”, y > x OrElse y > z)
Console.WriteLine(“X> ORELSE Z>Y={0}”, x > y OrElse z > y)
Console.WriteLine(“AndALso 与and 的区别是，如果第一个表达式False就返回False不计算后面了,提高了效率”)
Console.WriteLine(“OrElse 与Or 的区别是，如果第一个表达式True 就返回TRue不计算后面了,提高了效率”)
Console.ReadKey()
