如何编写VB.NET 接口程序

可以的，把项目的类型设成类库，将所有的函数用Public修饰附封装在类里面，生成dll文件。这样别人就可以在别人项目属性的引用页里面添加对你的dll文件的引用，然后导入命名空间，直接使用了。

比如说，在一个项目里：

NameSpace Controller

Public Class ControlMachine

Public Sub Boot()

End Sub

Public Sub Shutdown()

End Sub

End Class

End NameSpace

进入另一个项目的项目属性，进入引用页，添加到那个dll文件的引用。在代码中：

Imports Controller '加在代码文档的最顶端

使用：

Dim controller As New ControlMachine

controller.Boot()

controller.Shutdown()

VB.NET编程语法

vb编写net你这是vb.netvb编写net的代码,vb中不允许那么写:

Dim

strdx()

As

String

=

{"0",

"0",

"0"}

'定义个数组,从后面的值能看的出最大下标是2,也就是strdx(0),strdx(1)和strdx(2),3个的默认值都为0

Dim

calcount1

As

String

=

"0"

'定义个字符串变量

Dim

calcount2

As

String

=

"0"

Dim

strvalue

As

Boolean

=

False

'定义strvalue为bool值,改类型变量只有true和false

2种值

If

strdx(0)

=

"0"

Then

TextBox1.Text

=

strdx(0)

"."

这是字符串连接符号,和"+"的区别是,vb编写net他把左右2边的内容直接连接的,而"+"可能会编程运算符,例如

2

3

=

"23"

而

2

+

3

=

5

ElseIf

strvalue

=

False

Then

strdx(0)

=

strdx(0)

"0"

TextBox1.Text

=

strdx(0)

"."

strvalue

=

True

Else

strdx(0)

=

strdx(0)

"0"

TextBox1.Text

=

strdx(0)

Select

Case

calcount1

'

这里开始是分支语句

Case

"+"

TextBox1.Text

=

Str(Val(strdx(1))

+

Val(strdx(0)))
