if方式
if user="小强" then
response.write "小强"
elseif user="小雪" then
response.write "小雪"
end if

Select方式
user为要判断的变量。如果user是字符串类型如:user="123",则case中不可以用case 123,否则会出错。需要以case "123"加双引号方式判断。除非user=123是数字类型才可以case 123来判断
Select Case user
    Case "小强"
        response.write "小强"
    Case "小雪"
        response.write "小雪"
    Case Else
        response.write "谁都不是"
End Select
