Most of the properties are also used in ADO. All properties and des criptions is from msdn. 源代码网推荐 源代码网推荐 NameDefaultDes criptionApplication Name The name of the application, or ".Net SqlClient Data Provider" if no application name is provided.AttachDBFilename 源代码网推荐 -or- 源代码网推荐 extended properties 源代码网推荐 -or- 源代码网推荐 Initial File Name The name of the primary file, including the full path name, of an attachable database. The database name must be specified with the keyword "database".Connect Timeout 源代码网推荐 -or- 源代码网推荐 Connection Timeout15The length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error.Connection Lifetime0When a connection is returned to the pool, its creation time is compared with the current time, and the connection is destroyed if that time span (in seconds) exceeds the value specified by connection lifetime. Useful in clustered configurations to force load balancing between a running server and a server just brought on-line.Connection Reset"true"Determines whether the database connection is reset when being removed from the pool. Setting to "false" avoids making an additional server round-trip when obtaining a connection, but the programmer must be aware that the connection state is not being reset.Current Language The SQL Server Language record name.Data Source 源代码网推荐 -or- 源代码网推荐 Server 源代码网推荐 -or- 源代码网推荐 Address 源代码网推荐 -or- 源代码网推荐 Addr 源代码网推荐 -or- 源代码网推荐 Network Address The name or network address of the instance of SQL Server to which to connect.Enlist"true"When true, the pooler automatically enlists the connection in the creation thread"s current transaction context.Initial Catalog 源代码网推荐 -or- 源代码网推荐 Database The name of the database.Integrated Security 源代码网推荐 -or- 源代码网推荐 Trusted_Connection"false"Whether the connection is to be a secure connection or not. Recognized values are "true", "false", and "sspi", which is equivalent to "true".Max Pool Size100The maximum number of connections allowed in the pool.Min Pool Size0The minimum number of connections allowed in the pool.Network Library 源代码网推荐 -or- 源代码网推荐 Net"dbmssocn"The network library used to establish a connection to an instance of SQL Server. Supported values include dbnmpntw (Named Pipes), dbmsrpcn (Multiprotocol), dbmsadsn (Apple Talk), dbmsgnet (VIA), dbmsipcn (Shared Memory) and dbmsspxn (IPX/SPX), and dbmssocn (TCP/IP). 源代码网推荐 The corresponding network DLL must be installed on the system to which you connect. If you do not specify a network and you use a local server (for example, "." or "(local)"), shared memory is used.Packet Size8192Size in bytes of the network packets used to communicate with an instance of SQL Server.Password 源代码网推荐 -or- 源代码网推荐 Pwd The password for the SQL Server account logging on.Persist Security Info"false"When set to "false", security-sensitive information, such as the password, is not returned as part of the connection if the connection is open or has ever been in an open state. Resetting the connection string resets all connection string values including the password.Pooling"true"When true, the SQLConnection object is drawn from the appropriate pool, or if necessary, is created and added to the appropriate pool.User ID The SQL Server login account.Workstation IDthe local computer nameThe name of the workstation connecting to SQL Server. 源代码网推荐 源代码网推荐 Note 源代码网推荐 Use ; to separate each property. 源代码网推荐 If a name occurs more than once, the value from the last one in the connectionstring will be used. 源代码网推荐 If you are building your connectionstring in your app using values from user input fields, make sure the user can"t change the connectionstring by inserting an additional property with another value within the user value.
