使用自定义类时出现编译错误

[szjhxu]

环境：VS2010
语言：VB.NET
现象：创建了一个类文件MyClass.vb存放在APP_Code文件夹中，其中含有一个类ClassWX，以及若干方法与函数。调用页面中使用妱下语句创建对象及调用：
Dim wx As New ClassWX
wx.SendMessage("123456", "TEST")
在本地调试运行时，可以正常执行；上传到服务器以后打开页面就出错：

Compilation Error

Line 256: Dim wx As New ClassWX
Line 257: wx.SendMessage("123456", "TEST")

烦请大家给予解答，先谢了！

不要放在APP_Code文件夹下，自己新建一个文件夹，然后把类放进去。

搞定了，原来只要把类文件名与类名取成一样即可。
