从课堂调用func [英] Call func from class

问题描述

大家好！我有一个Vb.net的新问题。现在我正在编写在新类中创建的函数。但后来我想在一些form1,2,3中的代码中使用它....我怎么能从form1引用这个函数？我已经尝试过form1这个：class1.MyFunction ......但它不起作用！

Hi everyone!!! I have a new problem with Vb.net. Now i''m writting the function that have been created in new class. But then i want to use it in a code in some form1, 2, 3.... How could i refer to this function from the form1? I''ve tried in form1 this: class1.MyFunction...but it doesn''t work!

推荐答案

除非函数是共享只能通过类实例访问，而不能通过类名访问。但如果它是共享，它就无法访问任何非共享类变量或方法。



所以如果你需要要使用类数据，您需要查找或创建类的实例：

Unless the function is Shared is can only be accessed via a class instance, not the class name. But if it is Shared it cannot access any non-shared class variables or methods.

So if you need it to work with class data, you need to either find or create an instance of your class:

Dim mc As New class1()
mc.MyFunction()

我已经解决了。



共享MyFunction（byval ...）as byte

.....

结束函数< br $>


必须定义为共享

I''ve solved it.

Shared MyFunction(byval...) as byte
.....
End Function

It must have been defined as Shared
