c调用vb.net C调用restful

一个C++的DLL在vb.net或C#中调用问题

建议用CLRInsideOut这个软件自动声明。这是我用它翻译成vb.net声明的结果：

把里面的Unknown换成你用的dll名称

C语言转换为VB.NET

Option Explicit On

Option Strict On

Imports System

Module Program

Sub Main()

Dim y,m,t As Integer

begin:

' 输入数据时一行一个

y=CInt(Console.ReadLine())

m=CInt(Console.ReadLine())

t=CInt(Console.ReadLine())

If y

200 Then

Console.WriteLine("ERROR")

goto begin

End If

pr(y,m,t)

Console.Write("Press any key to continue . . . ")

Console.ReadKey(True)

End Sub

Function pr(y As Integer,m As Integer,t As Integer) As Integer

Dim ye,[Me],i As Integer

ye=CInt((m+t-2)/12+y)

[Me]=(m+t-2) Mod 12+1

End If

End Function

Function mday(y As Integer,m As Integer) As Integer

Dim day As Integer()={0,31,28,31,30,31,30,31,31,30,31,30,31}

vs2005中 c++怎样调用vb.net生成的dll

1、先引用你的dll（不要说你不知道怎么引用）

2、using你dll的命名空间

3、在代码中声明dll中的类（如：Lyric * l = new Lyric();）

4、接着开始编程

假如你的dll中的Lyric类有GetLyric（FileName）的方法，就直接写上去就可以了（如：String * s = l.GetLyric("C:\\1.lrc");）

如果你是要在C++中编辑这个已经生成的DLL，那是不可能的

我不是很会c++，有无法错误自己改

请帮忙将以下C语言代码转换为VB.NET代码，谢谢！

vb.net 调用C语言可执行程序并传值？

在c语言中每一个变量都有两个属性一个是值，一个是址。比如inta=2;变量a的值是2，变量a的地址，可以用取地址

操作符

获取，即a。因此以C语言的函数传递中具备两种方式传递参数，一种是传址，一种传值。比如voidf1(intv){;}//函数f1v
