在asp.net中的WEB程序的设置中我们必须用到Web.config来存储数据库连接字.事实上这是个很好的做法,因为可以省去我们很多的麻烦还可以帮助我们避免不必要的错位,是的很多情况下我就是这样做.它通过XML来记录这些信息.具体的是在....这个标记中来记录的.这里请看一个ORACLE的例子如下:
string conn = ConfigurationSettings.AppSettings["ORACLEConnectionString"];
OleDbConnection myConnection = new OleDbConnection(conn);
很轻松是吗?不必每次都输入同样的连接字,也不要记住那些讨厌的信息了,只需要起一个好记的名字就可以.好了下面我在来给出其他的一些连接字:
MYSQL的连接字:
ConnectionString = "Data Source=localhost;" +
"Database=mySQLDatabase;" +
"User ID=myUsername;" +
"Password=myPassword;" +
"Command Logging=false";
OLE DB的:
IBM AS/400 OLE DB 的
' VB.NET
Dim oOleDbConnection As OleDb.OleDbConnection
Dim sConnString As String = _
"Provider=IBMDA400.DataSource.1;" & _
"Data source=myAS400DbName;" & _
"User Id=myUsername;" & _
"Password=myPassword"
oOleDbConnection = New OleDb.OleDbConnection(sConnString)
oOleDbConnection.Open()
JET OLE DB 的
' VB.NET
Dim oOleDbConnection As OleDb.OleDbConnection
Dim sConnString As String = _
"Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=C:/myPath/myJet.mdb;" & _
"User ID=Admin;" & _
"Password="
oOleDbConnection = New OleDb.OleDbConnection(sConnString)
oOleDbConnection.Open()
Oracle OLE DB 的
' VB.NET
Dim oOleDbConnection As OleDb.OleDbConnection
Dim sConnString As String = _
"Provider=OraOLEDB.Oracle;" & _
"Data Source=MyOracleDB;" & _
"User ID=myUsername;" & _
"Password=myPassword"
oOleDbConnection = New OleDb.OleDbConnection(sConnString)
oOleDbConnection.Open()
SQL Server OLE DB 的
' VB.NET
Dim oOleDbConnection As OleDb.OleDbConnection
Dim sConnString As String = _
"Provider=sqloledb;" & _
"Data Source=myServerName;" & _
"Initial Catalog=myDatabaseName;" & _
"User Id=myUsername;" & _
"Password=myPassword"
oOleDbConnection = New OleDb.OleDbConnection(sConnString)
oOleDbConnection.Open()
Sybase ASE OLE DB 的
' VB.NET
Dim oOleDbConnection As OleDb.OleDbConnection
Dim sConnString As String = _
"Provider=Sybase ASE OLE DB Provider;" & _
"Data Source=MyDataSourceName;" & _
"Server Name=MyServerName;" & _
"Database=MyDatabaseName;" & _
"User ID=myUsername;" & _
"Password=myPassword"
oOleDbConnection = New OleDb.OleDbConnection(sConnString)
oOleDbConnection.Open()
SQL Server在System.Data.SqlClient
SqlConnection oSQLConn = new SqlConnection();
oSQLConn.ConnectionString = "Data Source=(local);" +
"Initial Catalog=mySQLServerDBName;" +
"Integrated Security=SSPI";
oSQLConn.Open();
这里都是用VB.NET写的，希望能对用VB写ASP.NET的朋友一点帮助.
