Hi,

Where want to use Conn.open and Conn.close in sql server. Whats the use of it.

Thanks in Advance.

推荐答案

如果您不知道它的用途，那么想使用"就没有意义了.

这不是"Conn".从System.Data.Common.DbConnection派生的类很少，请参见:

http://msdn.microsoft.com/en-us/library/system. data.sqlclient.sqlconnection.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.data.common.dbconnection.open.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.data.common.dbconnection.close.aspx [ ^ ].

一个快速的答案应该足够了:您要使用它，否则将无法正常工作.

If you don''t know the use of it, your "want to use" makes no sense.

And this is not "Conn". There are few classes derived from System.Data.Common.DbConnection, see:

http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.aspx[^],
http://msdn.microsoft.com/en-us/library/system.data.common.dbconnection.open.aspx[^],
http://msdn.microsoft.com/en-us/library/system.data.common.dbconnection.close.aspx[^].

A quick answer should be enough: you want to use it because otherwise nothing can work.

conn.open()用于连接数据库

conn.close()用于断开与数据库的连接

conn.open()is used to connecting to database

conn.close()is used to disconnecting from database

首先了解连接和断开连接的体系结构将对您有很大帮助

Hi,
