上面的例子连接到SQL Server。

我的要求是连接到Oracle DB.I没有发现我可以用来连接到Oracle DB的文件保护程序的类。如果您有任何想法请帮助。非常感谢。

您可以使用GenericDatabaseStorage<T>类，该类可以使用任何ADO.NET IDBConnection类型。以下是FileHelpers source的示例。

[TestClass] 
public class GenericDatabaseStorageTests 
{ 
    [TestMethod] 
    public void CurrencyOracleExtractToFile() 
    { 
     GenericDatabaseStorage<OracleConnection, OracleCommand> storage = 
      new GenericDatabaseStorage<OracleConnection, OracleCommand>( 
       typeof(TestRecord), 
       "User Id=SHELL;Password=shell;Data Source=ora9dev" 
      ); 

     storage.SelectSql = "SELECT * FROM CURRENCY"; 
     storage.FillRecordCallback = new FillRecordHandler(FillRecordOrder); 

     FileDataLink.EasyExtractToFile(storage, "tempord.txt"); 

     FileDataLink link = new FileDataLink(storage); 
     link.ExtractToFile("tempord.txt"); 

     TestRecord[] res = (TestRecord[])CommonEngine.ReadFile(typeof(TestRecord), "tempord.txt"); 

     if (File.Exists("tempord.txt")) 
      File.Delete("tempord.txt"); 

     Assert.AreEqual(3, res.Length); 

     Assert.AreEqual("AED", res[ 0 ].CurrencyCode); 
     Assert.AreEqual("AFA", res[ 1 ].CurrencyCode); 
     Assert.AreEqual("ALL", res[ 2 ].CurrencyCode); 
    } 

    public void FillRecordOrder(object rec, object[ ] fields) 
    { 
     TestRecord record = (TestRecord)rec; 

     record.CurrencyCode = (string)fields[ 0 ]; 
     record.Name = (string)fields[ 1 ]; 
    } 
}
