如何使用 Microsoft.ACE.OLEDB 和 SqlBulkCopy 正确导入启用了换行的 excel 列

Question

我正在使用批量插入将行从 excel sheet 导入 sql 服务器 table。 excel 源代码中的某些列启用了换行，它们导致了一些问题。

如果说 "wrapped text (1)" 和 "wrapped text (2)"，它们将在 excel 单元格中显示如下。

wrapped text (1) 
wrapped text (2)

我遇到的问题是，当该行导入 SQL 服务器时，它们将如下所示

wrapped text (1)wrapped text (2)//Note that there is no space between the two texts

我希望他们看起来像下面这样

 wrapped text (1) wrapped text (2)//note the space between them

下面是我用于导入的简单代码

 public static void insertdata1(string strexcelConnectionString, string strcommand, string strsqlConnectionString, string strtrunsqlQuery, string strtablename)
    {
        using (OleDbConnection connection = new OleDbConnection(strexcelConnectionString))
        {
            connection.Open();
            OleDbCommand command = new OleDbCommand(strcommand, connection);
            //truncate the table before inserting new data.
            SqlConnection cnntrunc = new SqlConnection(strsqlConnectionString);
            //open the connection.
            cnntrunc.Open();
            //begin the transaction.
            SqlTransaction myTrans = cnntrunc.BeginTransaction();//New a transaction                        
            SqlCommand truntble = new SqlCommand();
            truntble.Transaction = myTrans;
            truntble.Connection = cnntrunc;
            try
            {
                //Create DbDataReader to Data Worksheet.
                using (DbDataReader dr = command.ExecuteReader())
                {                     
                    //Bulk Copy to SQL Server.
                    using (SqlBulkCopy bulkCopy = new SqlBulkCopy(strsqlConnectionString))
                    {
                        bulkCopy.DestinationTableName = strtablename;
                        bulkCopy.WriteToServer(dr);
                    }
                    //commit the transaction.
                    myTrans.Commit();
                }
            }
            catch (OleDbException ex)
            {
               //my error handling code here
            }
            catch (InvalidOperationException ex)
            {
                myTrans.Rollback();
                //more logging here
                throw ex;
            }
            finally
            {
                cnntrunc.Close();
            }
        }
    }

打击是我的excel连接字符串

strexcelConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Server.MapPath(strfilename) + "; Extended Properties=\"Excel 12.0 XML;HDR=YES;IMEX=1;\"";
