c#-4.0 - 使用 Unicode 字符读取 csv 文件会引发异常

Question

CSV 文件可能包含多语言字符。

下面是我的阅读代码DataView

List<BulkUser> _lstBulkUser = new List<BulkUser>();
            DataView BlukUserView;

            try
            {
                using (SqlDataSource _SqlDataSource = new SqlDataSource())
                {
                    //_SqlDataSource.ConnectionString = "Dsn=outlook;dbq=D:\\selvam\\projectlist\\lates\\trunk\\SLVconsoleApp\\SLVconsoleApp.Web\\Uploads\\CSVFiles;defaultdir=D:\\selvam\\projectlist\\lates\\trunk\\SLVconsoleApp\\SLVconsoleApp.Web\\Uploads\\CSVFiles;driverid=27;fil=text;maxbuffersize=2048;pagetimeout=5";
                    _SqlDataSource.ConnectionString = "Dsn=" + ConfigurationManager.AppSettings["OutlookDns"].ToString() + ";dbq=" + ConfigurationManager.AppSettings["OutlookFileFolder"].ToString() + ";defaultdir=" + ConfigurationManager.AppSettings["OutlookFileFolder"].ToString() + ";driverid=27;fil=text;maxbuffersize=2048;pagetimeout=5";
                    _SqlDataSource.SelectCommand = "SELECT [First Name] As First_Name, [Last Name] AS LAST_NAME, Company, [E-mail Address] AS EMAILID FROM [" + Filename + "]";
                    _SqlDataSource.ProviderName = "System.Data.Odbc";
                    BlukUserView = (DataView)_SqlDataSource.Select(DataSourceSelectArguments.Empty);
                    int i = 1;
                    _lstBulkUser = (from value in BlukUserView.Table.Select() select new BulkUser { ID = Convert.ToString(i++), FirstName = Convert.ToString(Encoding.UTF8.GetString((byte[])value["First_Name"])), LastName = value["LAST_NAME"].ToString(), EmailId = value["EMAILID"].ToString(), Company = value["Company"].ToString() }).ToList();
                    if (File.Exists(ConfigurationManager.AppSettings["OutlookFileFolder"].ToString() + "\\" + Filename))
                    {
                        File.Delete(ConfigurationManager.AppSettings["OutlookFileFolder"].ToString() + "\\" + Filename);
                    }
                }
            }
            catch (Exception ex)
            { 
            }

它抛出你nable to cast object of type 'System.String' to type 'System.Byte[]'.

即使我尝试了 Unicode 字符，它也不是！我该如何克服这个问题？

CSV 不支持多语言字符。我已经检查到 Ms-office 2010。

最好保存为 xls 或 xlsx。处理这种情况的最简单方法。
