CData ADO.NET Provider for IBM Cloud Object Storage は、IBMCloudObjectStorageConnection に標準DbConnection オブジェクトを実装しています。IBMCloudObjectStorageConnectionStringBuilder 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。IBMCloudObjectStorageConnection 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 (IBMCloudObjectStorageConnection connection =   
  new IBMCloudObjectStorageConnection("ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;"))  
{  
  connection.Open();  
}

VB.NET

Using connection As New IBMCloudObjectStorageConnection("ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;")
  connection.Open
End Using

IBMCloudObjectStorageConnectionStringBuilder 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#

IBMCloudObjectStorageConnectionStringBuilder builder =
  new IBMCloudObjectStorageConnectionStringBuilder("ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;");
  //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 = "ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;";
  //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 IBMCloudObjectStorageConnectionStringBuilder = New IBMCloudObjectStorageConnectionStringBuilder("ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;")
'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 = ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;"
'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
