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--
Public Function ff() As Boolean
ff=true
End Function
--C#
public bool ff()
{
return true;
}
----
这里的 ff=true 是相当于 C#里的 return true; 是给vb函数自身返回值用的.
--VB--
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ff=true 'vb里可以省略函数的小括号()
End Sub
--C#--
private void Form_Load(System.Object sender, System.EventArgs e)
{
ff() == true;
}
这里的 ff=true 是相当于 C#里的 ff() == true; 是判断.
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：

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));
}

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;
}

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
这需要三个步骤：
第一步：创建一个C#项目，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，你成功了！
