Code からの接続
CData ADO.NET Provider for RSS は、RSSConnection に標準DbConnection オブジェクトを実装しています。RSSConnectionStringBuilder 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。RSSConnection 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 (RSSConnection connection =
new RSSConnection("URI=http://myservice/myfeed/;"))
{
connection.Open();
}
VB.NET
Using connection As New RSSConnection("URI=http://myservice/myfeed/;")
connection.Open
End Using
RSSConnectionStringBuilder 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#
RSSConnectionStringBuilder builder =
new RSSConnectionStringBuilder("URI=http://myservice/myfeed/;");
//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 = "URI=http://myservice/myfeed/;";
//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 RSSConnectionStringBuilder = New RSSConnectionStringBuilder("URI=http://myservice/myfeed/;")
'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 = URI=http://myservice/myfeed/;"
'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
