vb.net汉字转换 vbnet string转date

如何用vb.net将汉字转换成拼音阿

public string hz2py(string hz) //获得汉字的区位码

{

byte[] sarr = System.Text.Encoding.Default.GetBytes(hz);

int len = sarr.Length;

if (len1)

{

byte[] array = new byte[2];

array = System.Text.Encoding.Default.GetBytes(hz);

int i1 = (short)(array[0] - '\0');

int i2 = (short)(array[1] - '\0');

//unicode解码方式下的汉字码

// array = System.Text.Encoding.Unicode.GetBytes(hz);

// int i1 = (short)(array[0] - '\0');

// int i2 = (short)(array[1] - '\0');

// int t1 = Convert.ToInt32(i1,16);

// int t2 = Convert.ToInt32(i2,16);

int tmp=i1*256+i2;

Q1: vb.net怎么把汉字转换为GB2312编码,例如“广东”变成%B9%E3%B6%AB

GB2312是GBK编码vb.net汉字转换的子集vb.net汉字转换，使用GBK编码函数即可

'GBK编码(结果以百分号%进行分隔)

Public Function GBKEncode(ByVal sInput As String) As String

Dim ret_GBKEncode As String = ""

Dim i As Integer

Dim startIndex As Integer = 0

Dim endIndex As Integer

Dim x() As Byte = System.Text.Encoding.Default.GetBytes(sInput) '字符以及字符串在vb2008中都是以unicode编码存储vb.net汉字转换的

endIndex = x.Length - 1

For i = startIndex To endIndex

ret_GBKEncode = "%" Hex(x(i))

Next

Return ret_GBKEncode

End Function

'GBK解码

Public Function GBKDecode(ByVal sInput As String) As String

sInput = sInput.Replace("%", "")

Dim ret_GBKDecode As String = ""

Dim sLen As Integer = sInput.Length

Dim n As Integer = sLen \ 2

Dim sBytes(0 To n - 1) As Byte

'转化为字节码

For i As Integer = 1 To n

sBytes(i - 1) = CByte("H" sInput.Substring(2 * i - 2, 2))

Next

'将字节码转化为字符串

ret_GBKDecode = System.Text.Encoding.Default.GetString(sBytes)

Return ret_GBKDecode

End Function

Q2: vb.net 2008 如何将简体中文跟繁体中文互转呢？

原来还有这么个功能，那有没有转换为拼音的方法？

我比你运气好，两个都有效：

Public Class Form1

    Private Declare Function LCMapString Lib "kernel32" Alias "LCMapStringA" (ByVal Locale As Integer, ByVal dwMapFlags As Integer, ByVal lpSrcStr As String, ByVal cchSrc As Integer, ByVal lpDestStr As String, ByVal cchDest As Integer) As Integer

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim cString As String = "中华人民共和国"

        cString = (StrConv(cString, VbStrConv.TraditionalChinese))

        MsgBox(cString)

        cString = (StrConv(cString, VbStrConv.SimplifiedChinese))

        MsgBox(cString)

        Dim rString As String = Space(14)

        LCMapString(H804, H4000000, cString, 14, rString, 14)

        MsgBox(rString)

        cString = rString

        LCMapString(H804, H2000000, cString, 14, rString, 14)

        MsgBox(rString)

    End Sub

End Class

StrConv参数不对，api 函数Long型要改为Integer类型。

Q3: VB.NET中怎么实现 汉字转换拼音呢

建立一个表，每个拼音都跟多个汉字对应。可以通过汉字，找出对应的一个拼音，也可以通过拼音，找出一堆汉字。
