如何把下面用vb.net语言编写的代码改成c#

给你个网站看

可在线将vb.net代码转成c＃的，我用过，还可以的，但是转后也要改动一些。这里还有将c＃转vb.net的。

这是我转的：

string[] ArrValue = new string[43];

int Nums;

public void Page_Load(object Sender, EventArgs E)

{

int I;

if (!IsPostBack) {

for (I = 1900; I = 2101; I++) {

ListItem IItem = new ListItem();

IItem.Text = (string)I;

if (I == Year(Now)) {

IItem.Selected = "True";

}

DropYear.items.add(IItem);

}

for (I = 1; I = 12; I++) {

ListItem IItem = new ListItem();

IItem.Text = (string)I;

if (I == Month(Now)) {

IItem.Selected = "True";

}

DropMonth.items.add(IItem);

}

}

DispDetail(Conversion.Val(DropYear.SelectedItem.Text), Conversion.Val(DropMonth.SelectedItem.Text));

}

public void DispDetail(int YYear, int MMonth)

{

System.DateTime theDate;

int theYear;

int theMonth;

int theDay;

int theWeek;

int theFirstNum;

int NumOfMonth;

int i;

string theStr;

theYear = YYear;

theMonth = MMonth;

theDay = 1;

//获得所要查询的月的第一天日期

theDate = DateSerial(theYear, theMonth, theDay);

//确定所要查询的第一天是星期几

theWeek = weekday(theDate);

theFirstNum = theWeek;

//确定所要查询的月的天数

NumOfMonth = GetDayNum(theyear, themonth);

for (i = 0; i = 41; i++) {

ArrValue(i) = "";

}

for (i = 0; i = NumOfMonth - 1; i++) {

ArrValue(theFirstNum - 1 + i) = i + 1;

}

}

public object GetDayNum(int YYear, int MMonth)

{

object functionReturnValue = null;

if (MMonth == 1 | MMonth == 3 | MMonth == 5 | MMonth == 7 | MMonth == 8 | MMonth == 10 | MMonth == 12) {

functionReturnValue = 31;

}

else {

if (MMonth == 4 | MMonth == 6 | MMonth == 9 | MMonth == 11) {

functionReturnValue = 30;

}

else {

if (((YYear % 4 == 0) (YYear % 100 != 0)) | (YYear % 400 == 0)) {

functionReturnValue = 29;

}

else {

functionReturnValue = 28;

}

}

}

return functionReturnValue;

}

怎样将VB代码换成C

可以试试VBto Converter

VBto Converter是一款VB语言转换软件，它支持将MS Visual Basic资源文件（包括源代码）转换成MS VC++ MFC, VC++.NET (CLR), VBNET, C#, J#, Borland C++ Builder, Borland Delphi源文件。

vb.net中的数据强制转化问题，谁帮我把这段C#转化为VB.net的语言

强制类型转换在VB.NET中用Ctype()函数实现的。

Dim drv As DataRowView = CType(comboBox1.SelectedItem, DataRowView)

另外：comboBox1.SelectedItem 不是 string 类型，而是 object 类型。ComboBox 下拉显示文字是通过调用 Object.ToString() 方法实现的。

vb.net如何与c语言做的dll互相传递字符串

首先是C的DLL（我的项目叫ConsoleApplication2.dll）：

#include Windows.h

// 导出Test函数，供外部使用

extern "C" __declspec(dllexport) BSTR __cdecl Test(LPSTR p);

BOOL WINAPI DllMain(

HINSTANCE hinstDLL,

DWORD fdwReason,

LPVOID lpReserved)

{

switch (fdwReason)

{

case DLL_PROCESS_ATTACH: break;

case DLL_THREAD_ATTACH: break;

case DLL_THREAD_DETACH: break;

case DLL_PROCESS_DETACH: break;

}

return TRUE;

}

BSTR __cdecl Test(LPSTR p)

{

p[0] = 'X';

return SysAllocString((BSTR)p);

}

然后是VB.Net项目：

Imports System.Runtime.InteropServices

Imports System.Text

Module Module1

    REM 生成的是ConsoleApplication2.dll，名字与C里面相同

    DllImport("ConsoleApplication2.dll", CharSet:=CharSet.Auto, CallingConvention:=CallingConvention.Cdecl)

    Public Function Test(MarshalAs(UnmanagedType.LPTStr) ByVal str As StringBuilder) As MarshalAs(UnmanagedType.BStr) String

    End Function

    Sub Main()

        Dim str As StringBuilder = New StringBuilder("Hello")

        Dim rstr As String = Test(str)

        Console.WriteLine(rstr)

        Console.ReadKey()

    End Sub

End Module

运行结果：
