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;

}
