ADO.Net 之 Access批量Insert

跟SQLServer批量insert步骤一样:

1,构造DataTable

            /// <summary>
            /// 构造Table
            /// </summary>
            /// <returns></returns>
            public DataTable BuildTable()
            {
                try
                {
                    DataTable dt = new DataTable("Person");//与目标表名一致
                    DataColumn ID = dt.Columns.Add("ID", typeof(String));
                    ID.AllowDBNull = false;//空值
                    ID.Unique = true;//唯一
                    dt.Columns.Add("ksj", typeof(String));
                    return dt;
                }
                catch (Exception ex)
                {
                    return null;
                }
            }

2,封装并为Table赋值

     DataTable dt =BuildTable();
                for (int i = 0; i < 10000; i++)
                {
                    DataRow dr = dt.NewRow();
                    dr["ID"] = i.ToString();
                    dr["ksj"] = "pil";
                    dt.Rows.Add(dr);
                }

3,OleDbDataAdapter批量提交Table

    public void insert(DataTable dt1)
            {
                try
                {
                    GetOleDbConn();
                    OpenConn();
                    OleDbCommand cmd2 = new OleDbCommand("insert into Person(ID,ksj)) values (@ID,@ksj)");//加@等同于转义关键字,最好加
                    OleDbDataAdapter adapt = new OleDbDataAdapter("select * from Person", oleConn);// 把目标表数据拿到OleDbDataAdapter 
                    OleDbCommandBuilder OleDbCmdBud = new OleDbCommandBuilder(adapt);
                    OleDbParameter ID = new OleDbParameter("@ID", OleDbType.VarWChar, 255);
                    OleDbParameter Names = new OleDbParameter("@ksj", OleDbType.VarWChar, 255);
                    adapt.Fill(dt1);
                    adapt.SelectCommand.Parameters.Add(ID);
                    adapt.SelectCommand.Parameters.Add(Names);
                    adapt.SelectCommand.Parameters["@ID"].SourceColumn = "ID";
                    adapt.SelectCommand.Parameters["@ksj"].SourceColumn = "ksj";
                    adapt.UpdateCommand = OleDbCmdBud.GetUpdateCommand();
                    if (dt1 != null)
                    {
                        adapt.Update(dt1);//这里开始提交了
                    }
                }
                catch (Exception ex)
                {
                     ex.Message;            }
            }
