SqlServer的连接字符串

 Standard Security:
  "Data Source=Aron1;Initial Catalog=pubs;User Id=sa;Password=asdasd;"
     - or -
  "Server=Aron1;Database=pubs;User ID=sa;Password=asdasd;Trusted_Connection=False"
     (both connection strings produces the same result)

Trusted Connection:
  "Data Source=Aron1;Initial Catalog=pubs;Integrated Security=SSPI;"
     - or -
  "Server=Aron1;Database=pubs;Trusted_Connection=True;"
     (both connection strings produces the same result)
  (use serverName/instanceName as Data Source to use an specifik SQLServer instance, only SQLServer2000)
 
Connect via an IP address:
  "Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=pubs;User ID=sa;Password=asdasd;"
  (DBMSSOCN=TCP/IP instead of Named Pipes, at the end of the Data Source is the port to use (1433 is the default))

For Example:
C#:
using System.Data.SqlClient;
SqlConnection oSQLConn = new SqlConnection();
oSQLConn.ConnectionString="Data Source=Aron1;Initial Catalog=pubs;User Id=sa;Password=asdasd;";
oSQLConn.Open();

VB.NET:
Imports System.Data.SqlClient
Dim oSQLConn As SqlConnection = New SqlConnection()
oSQLConn.ConnectionString="Data Source=Aron1;Initial Catalog=pubs;User Id=sa;Password=asdasd;"
oSQLConn.Open()
