Question

我在.net

中有CSV上传代码

在C＃

 string strConnString = "Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=D:\\csv;Extensions=asc,csv,tab,txt;Persist Security Info=False";
            DataSet ds;
            using (OdbcConnection oConn = new OdbcConnection(strConnString))
            {
                using (OdbcCommand oCmd = new OdbcCommand())
                {
                    oCmd.Connection = oConn;
                    oCmd.CommandType = System.Data.CommandType.Text;
                    oCmd.CommandText = "select * from [my.csv]";

                    OdbcDataAdapter oAdap = new OdbcDataAdapter();
                    oAdap.SelectCommand = oCmd;

                    ds = new DataSet();
                    oAdap.Fill(ds, "my");
                    oAdap.Dispose();                     
                    ds.Dispose();
                }
            }

在.VB

  Dim strConnString As String = "Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=D:\\csv;Extensions=asc,csv,tab,txt;Persist Security Info=False"

        Dim lOdbcConnection As New OdbcConnection(strConnString)
        '            lOdbcConnection.ConnectionString = strConnString
        'lOdbcConnection.Open()
        Using lOdbcCommand As New OdbcCommand, lOdbcDataAdapter As New OdbcDataAdapter
            lOdbcCommand.Connection = lOdbcConnection
            lOdbcCommand.CommandType = System.Data.CommandType.Text
            lOdbcCommand.CommandText = "select * from [my.csv]"

            lOdbcDataAdapter.SelectCommand = lOdbcCommand
            Dim ds As New DataSet()
            lOdbcDataAdapter.Fill(ds, "my")
            ds.Dispose()

            lOdbcDataAdapter.Dispose()

在C＃中工作正常但是在.VB中填充数据集时给出错误.-

错误[IM002] [Microsoft] [ODBC驱动程序管理器]未找到数据源名称且未指定默认驱动程序

我做错了什么？

Answer 1

您不需要转义VB.NET字符串中的\字符，因此“Dbq = D：\\ csv”应为“Dbq = D：\ csv”。这就是找不到您的数据源的原因。

使用ODBC在.NET中上传CSV
