備註

這個實作會 OleDbDataAdapter 開啟，如果尚未開啟，則會關閉 OleDbConnection 。這在必須針對兩個或多個OleDbDataAdapter物件呼叫 Fill 方法的應用程式中很有用。 OleDbConnection如果已經開啟，您必須明確呼叫 Close 或 Dispose 以關閉它。

當您建立的 OleDbDataAdapter實例時，下列讀取/寫入屬性會設定為下列初始值。

屬性	初始值
MissingMappingAction	`MissingMappingAction.Passthrough`
MissingSchemaAction	`MissingSchemaAction.Add`

您可以透過對屬性的個別呼叫來變更其中一個屬性的值。

備註

建構函式的 OleDbDataAdapter 這個多載會 selectConnectionString 使用參數來設定 SelectCommand 屬性。不過，它不會開啟連線。您仍然必須明確開啟連線。

當您建立的 OleDbDataAdapter實例時，下列讀取/寫入屬性會設定為下列初始值。

屬性	初始值
MissingMappingAction	`MissingMappingAction.Passthrough`
MissingSchemaAction	`MissingSchemaAction.Add`

您可以透過對屬性的個別呼叫來變更這些屬性的值。
