如何把下面用vb.net语言编写的代码改成c#
给vb.net项目转c你个网站看
可在线将vb.net代码转成c＃的vb.net项目转c，我用过vb.net项目转c，还可以的vb.net项目转c，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;
}

Q1: 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vb.net项目转c，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。

Q3: VB.NET object 转换到C#object问题
你实例化对象看看哈
VB 和C# 的object 在变异的时候是不一样的，你不做修改正常出错
object指对象，代表的是通用的对象，就是什么对象都可以表示，new只能表示固定的对象
还有注意一下大小写object和Object是不一样的
Q4: 在vs2008中怎样将vb的项目转换成c#的项目?
这需要三个步骤：
第一步：创建一个C#项目vb.net项目转c，在其中添加相应的窗体和引用，将VB2008中相应窗体上的控件复制到C#相应的窗体上；
第二步：使用C#与VB.NET转换工具软件或者到“”，将VB2008 的代码转换成C#代码。
第三步：工具软件或者在线转换，转换后的代码会有一些错误或者无法转换的部分，进行简单的人工修正。
OK，vb.net项目转c你成功vb.net项目转c了vb.net项目转c！
Q5: 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：
