Code からの接続
CData ADO.NET Provider for Gmail は、GmailConnection に標準DbConnection オブジェクトを実装しています。GmailConnectionStringBuilder 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。GmailConnection 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 (GmailConnection connection =
new GmailConnection("user=myuseraccount;password=mypassword;"))
{
connection.Open();
}
VB.NET
Using connection As New GmailConnection("user=myuseraccount;password=mypassword;")
connection.Open
End Using
GmailConnectionStringBuilder 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#
GmailConnectionStringBuilder builder =
new GmailConnectionStringBuilder("user=myuseraccount;password=mypassword;");
//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 = "user=myuseraccount;password=mypassword;";
//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 GmailConnectionStringBuilder = New GmailConnectionStringBuilder("user=myuseraccount;password=mypassword;")
'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 = user=myuseraccount;password=mypassword;"
'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
