.net - 使用 ADO.net(OLEDB) 导入 UTF-8 CSV 文件

Question

我使用此代码导入一个文本文件(.CSV)，但是当此文件是由UTF-8代码创建时，无法成功。只要我另存为ANSI代码(使用Note.exe)就可以了。

Function getDataset(ByVal sql As String, ByVal path As String) As DataSet
    'Try
    'Dim connstr As String = GetINI("Setting", "cString",     "Provider=Microsoft.Jet.OLEDB.4.0;Data Source= C:\DataSouce\DataBase.mdb", Application.StartupPath & "\setting.ini")
    Dim connstr As String = "Provider=Microsoft.jet.OLEDB.4.0;Data Source= " & path & "\;Extended Properties=""text;HDR=YES;FMT=Delimited"""
    Dim conn As OleDbConnection = New OleDbConnection(connstr)                   '("provider=microsoft.Jet.OLEDB.4.0;data source=" & CurDir() & "\data.mdb")
    Dim adapter1 As OleDb.OleDbDataAdapter = New OleDbDataAdapter(sql, conn)
    Dim cmd As OleDbCommand = New OleDbCommand
    Dim commandBuilder As OleDbCommandBuilder = New OleDbCommandBuilder(adapter1)
    getDataset = New DataSet
    adapter1.Fill(getDataset, "temp")
    'Catch ex As Exception
    '    MsgBox(ex.Message)
    'End Try

 End Function

我什至尝试构建这样的 schema.ini，也不行

[temp.CSV]
Format=Delimited(,)
ColNameHeader=false
MaxScanRows=0
CharacterSet= ANSI  
 （or  UTF-8 ）

VB 有一个内置的 csv 解析器。看看这篇文章:http://coding.abel.nu/2012/06/built-in-net-csv-parser/ .

TextFieldParser 位于 Microsoft.VisualBasic.FileIO 命名空间中。如果您在 C# 中构建模块，则必须导入它。
