二、所使用的Model類git
2.1 數據庫類sql

2.4 數據庫類型枚舉安全
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Help.DBAccessLayer.Model { public enum MDataBaseType { /// <summary> /// 未知數據庫 /// </summary> UNKNOW = 0, /// <summary> /// The mysql /// </summary> MYSQL = 1, /// <summary> /// The sqlserver /// </summary> SQLSERVER = 2, /// <summary> /// DB2 /// </summary> DB2 = 3 } }
