Implementazioni

GetEnumerator()

Esempio

Nell'esempio seguente viene usato il GetEnumerator metodo per ottenere un IDictionaryEnumerator oggetto utilizzato per enumerare le risorse in un file con estensione resx. L'esempio include una CreateResourceFile routine che crea il file di risorse necessario.

using System;
using System.Collections;
using System.Resources;

public class Example
{
   private const string resxFilename = @".\CountryHeaders.resx";
    
   public static void Main()
   {
      // Create a resource file to read.
      CreateResourceFile();
      
      // Enumerate the resources in the file.
      ResXResourceReader rr = new ResXResourceReader(resxFilename);
      IDictionaryEnumerator dict = rr.GetEnumerator();
      while (dict.MoveNext())
         Console.WriteLine("{0}: {1}", dict.Key, dict.Value);   
   }

   private static void CreateResourceFile()
   {
      ResXResourceWriter rw = new ResXResourceWriter(resxFilename);
      string[] resNames = {"Country", "Population", "Area", 
                           "Capital", "LCity" };
      string[] columnHeaders = { "Country Name", "Population (2010}", 
                                 "Area", "Capital", "Largest City" };
      string[] comments = { "The localized country name", "", 
                            "The area in square miles", "", 
                            "The largest city based on 2010 data" };
      rw.AddResource("Title", "Country Information");
      rw.AddResource("nColumns", resNames.Length);
      for (int ctr = 0; ctr < resNames.Length; ctr++) {
         ResXDataNode node = new ResXDataNode(resNames[ctr], columnHeaders[ctr]);
         node.Comment = comments[ctr];
         rw.AddResource(node);
      }
      rw.Generate();
      rw.Close();
   }
}
// The example displays the following output:
//       Title: Country Information
//       nColumns: 5
//       Country: Country Name
//       Population: Population (2010}
//       Area: Area
//       Capital: Capital
//       LCity: Largest City

      Do While dict.MoveNext()

      rw.AddResource("Title", "Country Information")
      rw.AddResource("nColumns", resNames.Length)
      For ctr As Integer = 0 To resNames.Length - 1
         Dim node As New ResXDataNode(resNames(ctr), columnHeaders(ctr))
         node.Comment = comments(ctr)
         rw.AddResource(node)
      Next
      rw.Generate()
      rw.Close()
   End Sub
End Module
' The example displays the following output:
'       Title: Country Information
'       nColumns: 5
'       Country: Country Name
'       Population: Population (2010}
'       Area: Area
'       Capital: Capital
'       LCity: Largest City

Commenti

Il GetEnumerator metodo recupera le coppie nome/valore nel flusso o nella stringa XML resource (con estensione resx) associata all'oggetto corrente ResXResourceReader . Tuttavia, se la UseResXDataNodes proprietà è impostata su true prima di chiamare GetEnumerator, gli elementi della risorsa vengono recuperati come ResXDataNode oggetti. In questo caso, tutti i nodi delle risorse vengono restituiti indipendentemente dal tipo.
