(转)使用 ConnectionStringBuilder 对象创建精确连接字符串

DBConnectionStringBuilder 对象能够验证所有可用的连接字符串设置.

它可以启动高级连接选项,如连接池,群集连接和异步访问.

DBConnectionStringBuilder 创建与数据库平台无关的代码过程中扮演一个重要角色.

它派生出 SqlConnectionStringBuilder、OracleConnectionStringBuilder、OdbcConnectionStringBuilder 和 
OleDbConnectionStringBuilder ,利用面向对象的特性可以容易的创建与平台无关的数据库应用程序.

用法:

C#

            SqlConnectionStringBuilder connbuilder = new SqlConnectionStringBuilder();
             connbuilder.DataSource = "localhost";
             connbuilder.UserID = "user";
             connbuilder.Password = "password";
             connbuilder.MinPoolSize = 5;
             connbuilder.MaxPoolSize= 20;
             SqlConnection conn = new SqlConnection(connbuilder.ConnectionString);
             conn.Open();

            DbConnectionStringBuilder builder = new DbConnectionStringBuilder();
            builder.ConnectionString = accountSet.DBSetting.ConnectionString;

            object dataSource = null;
            if (builder.TryGetValue(Const.DATASOURCE, out dataSource))
            {
                serverModel.DBIP = dataSource.ToString().Trim();
            }
