Question

我需要在SQL Server中插入1000多条记录。但是使用我的代码我只能插入1000条记录。请帮帮我。

using (SqlBulkCopy s = new SqlBulkCopy(dbConnection,SqlBulkCopyOptions.UseInternalTransaction, null))
{
     s.DestinationTableName = TableName;
     s.BatchSize = 10000;
     s.BulkCopyTimeout = 1800;
     foreach (var column in dt.Columns)
     {
         s.ColumnMappings.Add(column.ToString(), column.ToString());
     }
     s.WriteToServer(dt);
}

下面是我在项目中用于将批量数据从excel插入SQL服务器的实时工作代码

C＃代码：

public static DataSet Bindgrid_StoreInSQL(string path)
    {


            string strFileType = Path.GetExtension(path).ToLower();
            string connString = "";
            if (strFileType.Trim() == ".xls")
            {
                connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"";
            }
            else if (strFileType.Trim() == ".xlsx")
            {
                connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=2\"";
            }
            string query = "SELECT * FROM [Sheet1$]";
            OleDbConnection conn = new OleDbConnection(connString);
            OleDbCommand cmd = new OleDbCommand(query, conn);
            OleDbDataAdapter da = new OleDbDataAdapter(cmd);
            DataSet ds = new DataSet();
            da.Fill(ds);
            DataTable Exceldt = ds.Tables[0];

            //creating object of SqlBulkCopy    
            SqlBulkCopy objbulk = new SqlBulkCopy(OneStopMethods_Common.constring_Property);
            //assigning Destination table name    
            objbulk.DestinationTableName = "Tern_boq";


            objbulk.ColumnMappings.Add("ID", "ID");
            objbulk.ColumnMappings.Add("Bill_No", "Bill_No");
            objbulk.ColumnMappings.Add("Page_No", "Page_No");
            objbulk.ColumnMappings.Add("ItemNo", "ItemNo");
            objbulk.ColumnMappings.Add("Description", "Description");
            objbulk.ColumnMappings.Add("BOQ_Qty", "BOQ_Qty");
            objbulk.ColumnMappings.Add("UNIT", "UNIT");
            objbulk.ColumnMappings.Add("Category1", "Category1");
            objbulk.ColumnMappings.Add("Category2", "Category2");
            objbulk.ColumnMappings.Add("Category3", "Category3");
            objbulk.ColumnMappings.Add("Estimated_UnitRate", "Estimated_UnitRate");
            objbulk.ColumnMappings.Add("Estimated_Amount", "Estimated_Amount");



            //inserting Datatable Records to DataBase    
            conn.Open();
            objbulk.WriteToServer(Exceldt);


            SqlDatabase obj = new SqlDatabase(OneStopMethods_Common.constring_Property);
            string selquery = " select * from Tern_boq";
            return obj.ExecuteDataSet(CommandType.Text, selquery);




    }

它的工作正常，希望这可以给你一些想法，请让我知道你的想法或建议
