c项目转vb.net

vb6.0转型vb.net需要多长时间?c大概需要学习多久?

转VB.NET要几个月吧.转C估计够呛,我说的是懂,而不是只会写个简单的输出,要写的简单的输出只要几个小时...也行跟天赋直接挂钩.学C要忘记所有的VB呵呵跟练什么武功似的.

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.

C语言转换为VB.NET

Option Explicit On

Option Strict On

Imports System

Module Program

Sub Main()

Dim y,m,t As Integer

begin:

' 输入数据时一行一个

y=CInt(Console.ReadLine())

m=CInt(Console.ReadLine())

t=CInt(Console.ReadLine())

If y

Console.WriteLine("ERROR")

goto begin

End If

pr(y,m,t)

Console.Write("Press any key to continue . . . ")

Console.ReadKey(True)

End Sub

Function pr(y As Integer,m As Integer,t As Integer) As Integer

Dim ye,[Me],i As Integer

End Function

Function mday(y As Integer,m As Integer) As Integer

Dim ad As I

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！

请帮忙将以下C语言代码转换为VB.NET代码,谢谢！

' 输入数据时一行一个

If y100 Then

ye=y

[Me]=m

For i=0 To t-1

prmonth(ye,[me])

[Me]=[Me]+1

ye=ye+1

[me]=1

Next

Return 0

Function yam(y As Integer,m As Integer) As Integer

Dim st As String()={"未定义","一月","二月","三月","四月","五月","六月","七月","八月","九月","十月","十一月","十二月"}

Console.WriteLine(" {0} {1}",y,st(m))

Console.WriteLine("----------------------------")

Function ryear(y As Integer) As Integer

Return 1

Else

Dim ad As Integer=0

ad=ryear(y)

Return day(m)+ad

Function monday(y As Integer,m As Integer) As Integer

Dim i,daynum As Integer

For i=1 To m-1

Return md

Function prmonth(y As Integer,m As Integer) As Integer

Dim md As Integer=monday(y,m)

Dim daysnum As Integer=mday(y,m)

Dim days As Integer=daysnum+md

Dim i As Integer

yam(y,m)

Console.Write(" 日 一 二 三 四 五 六")

For i=0 To days-1

Console.WriteLine()

Console.Write(" ")

If i-md=0 Then

End Module
