(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();
}

.csharpcode .alt
{

width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
