VB.NET连接ORACLE数据库
请问VB.NET如何连接ORACLE数据库?

[解决办法]
下面的示例创建一个 OracleConnection，并在连接字符串中设置它的一些属性。

Visual Basic 复制代码
Public Sub CreateOracleConnection()
Dim connectionString As String = _
"Data Source=Oracle8i;Integrated Security=yes "

Using connection As New OracleConnection(connectionString)
connection.Open()
Console.WriteLine( "ServerVersion: " + connection.ServerVersion _
+ ControlChars.NewLine + "DataSource: " + connection.DataSource)
End Using
End Sub

Dim adapter As New OleDbDataAdapter

str4 = "select * from dept "

connection2 = New OleDbConnection "Provider=OraOLEDB.Oracle.1;User ID=scott;Data Source=hong;Password=tiger ")
adapter = New OleDbDataAdapter(str4, connection2)

Dim DataSet21 As DataSet = New DataSet
adapter.Fill(DataSet21, "dept ")
