DataSource=localhost;UserID=myusername;Password=mypassword;Database=mydatabase;ConnectTimeout=30;Pooling=True;Encryption=False 这个示例中,DataSource指定了本地SQLServer服务器名称,UserID和Password用于连接数据库,Database指定要连接的数据库名称,ConnectTimeout设置了连接超时时间,Pooling启用了连接池,Encryption则表...
Connection是会自动关闭的(timeout过时自动关闭),可在服务器内调节。Statement是不会自动关闭的,除非被垃圾回收。若有进一步问题,可直接HI我。
ConnectionTimeout Gets the time to wait (in seconds) while trying to establish a connection before terminating the attempt and generating an error. Credential Gets or sets the SqlCredential object for this connection. Database Gets the name of the current database or the database to be used...
