Code からの接続
CData ADO.NET Provider for Business b-ridge は、BusinessbridgeConnection に標準DbConnection オブジェクトを実装しています。BusinessbridgeConnectionStringBuilder を使用して、プログラムで接続文字列をビルド、パース、およびリビルドすることもできます。
Connection オブジェクトの作成
接続文字列の定義と認証については、接続の確立 を参照してください。BusinessbridgeConnection オブジェクトを作成する一般的な呼び出しは以下のとおりです。
C#
using (BusinessbridgeConnection connection =
new BusinessbridgeConnection("ConnectionProperty1=Value1;ConnectionProperty2=Value2"))
{
connection.Open();
}
VB.NET
Using connection As New BusinessbridgeConnection("ConnectionProperty1=Value1;ConnectionProperty2=Value2")
connection.Open
End Using
BusinessbridgeConnectionStringBuilder の使用
次のコード例は、ADO.NET 接続文字列ビルダーを使用して接続文字列をパースする方法を示します。
C#
BusinessbridgeConnectionStringBuilder builder =
new BusinessbridgeConnectionStringBuilder("ConnectionProperty1=Value1;ConnectionProperty2=Value2");
//Pass the connection string builder an existing connection string, and you can get and set any of the elements as strongly typed properties.
builder.ConnectionString = "ConnectionProperty1=Value1;ConnectionProperty2=Value2";
//Now that the connection string has been parsed,
// you can work with individual items:
builder.MyString = "new property";
builder.MyBoolean = true;
// You can refer to connection keys using strings,
// as well.
builder["Logfile"] = "test.log";
builder["Verbosity"] = 5;
VB.NET
Dim builder As BusinessbridgeConnectionStringBuilder = New BusinessbridgeConnectionStringBuilder("ConnectionProperty1=Value1;ConnectionProperty2=Value2")
'Pass the connection string builder an existing connection string, and you can get and set any of the elements using strongly typed properties.
builder.ConnectionString = ConnectionProperty1=Value1;ConnectionProperty2=Value2"
'Now that the connection string has been parsed,
' you can work with individual items:
builder.MyString = "new property"
builder.MyBoolean = True
' You can refer to connection keys using strings,
' as well.
builder("Logfile") = "test.log"
builder("Verbosity") = 5
