1、类库链接
private static OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OleDb.4.0;Data Source=|DataDirectory|\\zanlve.mdb;");
默认放在App_Data文件夹内即可。
2、插入操作
需要执行两次命令
/// <summary> /// 执行一条SQL语句 返回结果ID /// </summary> /// <param name="sqlstr"></param> /// <returns></returns> public static int ExecuteScalarSql(string sqlstr) { ConnOpen("conn"); OleDbCommand cmd = conn.CreateCommand(); cmd.CommandText = sqlstr; int count = cmd.ExecuteNonQuery(); cmd.CommandText = "SELECT @@IDENTITY"; int rowId = Convert.ToInt32(cmd.ExecuteScalar()); ConnClose("conn"); return rowId; }
