vb.net与c转换 vb进制转换
请大侠帮我将C代码转换成VB.Net，谢谢！
public function Calculate_CRC8(byval crc as uint16,byval n as uint16) as uint16

dim i as uint16
crc=crc xor n
for i=0 to 7
if crc and 1 then
crc=(crc1) xor H8c
else
crc=crc1
end if
next
return crc
end function
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。
请帮忙将以下C语言代码转换为VB.NET代码，谢谢！

vb.net 转 c#
--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.
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;
}
