无法将Excel导入到服务器中的DB表中

Question

我正在使用下面的代码将Excel数据导入到DB表中。该代码在我的本地工作正常，当我将此代码移动到服务器时，导入失败。此外，我没有收到任何错误消息，并且我成功保存了一条消息数据。

例如：excel有75,000个数据，只有13,500条记录被插入，并且excel文件的大小为5 MB。

有关可能的问题的任何建议？

喜删除数据读取器上你代码读取Excel文件的两倍，并使用数据集来填写你的SQL表：

请看下图：

DataTable dtexcel = new DataTable(); 

      using (OleDbConnection conn = new OleDbConnection(strCS)) 
      { 
       conn.Open(); 

       DataTable schemaTable = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" }); 

       //Looping a first Sheet of Xl File 
       DataRow schemaRow = schemaTable.Rows[0]; 
       string sheet = schemaRow["TABLE_NAME"].ToString(); 

       if (!sheet.EndsWith("_")) 
       { 
        string query = "SELECT * FROM [" + sheet + "]"; 
        OleDbDataAdapter daexcel = new OleDbDataAdapter(query, conn); 
        dtexcel.Locale = CultureInfo.CurrentCulture; 
        daexcel.Fill(dtexcel); 
       } 
      } 

      using (SqlConnection sqlconn = new SqlConnection(strCon)) 
      { 
       SqlCommand sqlcmd = new SqlCommand(sclearsql, sqlconn); 
       sqlconn.Open(); 
       sqlcmd.ExecuteNonQuery(); 
      } 


      using (SqlConnection sqlconn = new SqlConnection(strCon)) 
      { 
       using (SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(sqlconn)) 
       { 
        //Set the database table name 
        sqlBulkCopy.DestinationTableName = strSqlTable; 

        sqlconn.Open(); 

        sqlBulkCopy.WriteToServer(dtexcel); 

       } 
      }

您是否尝试过使用dts向导？如果你有一个Excel数据表，它是一个很好的工具。
您可以通过打开命令提示符来使用它。 windowsbutton + r，并写入cmd。
并从这里你写dtswizard
然后向导在一个新的窗口，您可以选择要插入Excel表格中打开。谷歌有很多教程。
希望你能使用这个
