VB6 Winsock解析中文乱码问题解决办法

在项目中遇到Winsock连接C#编写的socket服务端，取到的中文乱码。解决如下

Option Explicit
Private Declare Function WideCharToMultiByte Lib "kernel32" (ByVal CodePage As Long, ByVal dwFlags As Long, ByVal lpWideCharStr As Long, ByVal cchWideChar As Long, ByRef lpMultiByteStr As Any, ByVal cchMultiByte As Long, ByVal lpDefaultChar As String, ByVal lpUsedDefaultChar As Long) As Long
Private Declare Function MultiByteToWideChar Lib "kernel32" (ByVal CodePage As Long, ByVal dwFlags As Long, ByVal lpMultiByteStr As Long, ByVal cchMultiByte As Long, ByVal lpWideCharStr As Long, ByVal cchWideChar As Long) As Long
Private Const CP_UTF8 = 65001

Function Utf8ToUnicode(ByRef Utf() As Byte) As String
    Dim lRet As Long
    Dim lLength As Long
    Dim lBufferSize As Long
    lLength = UBound(Utf) - LBound(Utf) + 1
    If lLength <= 0 Then Exit Function
    lBufferSize = lLength * 2
    Utf8ToUnicode = String$(lBufferSize, Chr(0))
    lRet = MultiByteToWideChar(CP_UTF8, 0, VarPtr(Utf(0)), lLength, StrPtr(Utf8ToUnicode), lBufferSize)
    If lRet <> 0 Then
    Utf8ToUnicode = Left(Utf8ToUnicode, lRet)
    End If
End Function

读取到socket数据调用Utf8ToUnicode解决乱码。

Private Sub Winsock1_DataArrival(ByVal bytesTotal As Long)
    Dim dd As String
    Dim Data() As Byte
    Winsock1.GetData Data
    dd = Utf8ToUnicode(Data)
End Sub
