我得到的小语法错误 [英] little syntax error i got

问题描述

你好，
我尝试制作的这段代码有点麻烦.
我正在尝试拥有(如果是管理员的话)之类的东西
只有我要使用用户名，而不要使用管理员配置文件类型.

用户名是(sysadmin，管理员，备份.)

这是代码:

hello,
I am having a little trouble with this code I am trying to make.
I am trying to have like (if admin then do this) thing
only I would like to use usernames and not the administrator profile type.

The usernames are (sysadmin, administrator, backup.)

Here is the code:

If (LCase(Environment.UserName)) = (CStr("sysadmin") Or CStr("administrator") Or CStr("backup")) Then
    MessageBox.Show("You are an administrator")
Else
    MessageBox.Show("You are not an authorised user!")
End If

我得到的错误是:
从字符串"sysadmin"到类型"Double"的转换无效.

我想我需要尝试将用户名"sysadmin"转换为字符串或其他内容.

谁能告诉我正确的方法.


感谢

the error I am getting is:
Conversion from string "sysadmin" to type ''Double'' is not valid.

I think I need to try to convert my username "sysadmin" to string or somthing.

Can any one show me the right way of doing this.


thanks
