ResXResourceReader.GetEnumerator 方法

定義

命名空間:

System.Resources

組件:

System.Windows.Forms.dll

傳回目前 ResXResourceReader 物件的列舉程式。

public:
 virtual System::Collections::IDictionaryEnumerator ^ GetEnumerator();

public System.Collections.IDictionaryEnumerator GetEnumerator ();

abstract member GetEnumerator : unit -> System.Collections.IDictionaryEnumerator
override this.GetEnumerator : unit -> System.Collections.IDictionaryEnumerator

Public Function GetEnumerator () As IDictionaryEnumerator

傳回

IDictionaryEnumerator

目前 ResourceReader 物件的列舉值。

實作

GetEnumerator()

範例

下列範例會 GetEnumerator 使用 方法來取得 IDictionaryEnumerator 物件，該物件可用來列舉 .resx 檔案中的資源。 此範例包含建立 CreateResourceFile 必要資源檔的例程。

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

Module Example
   Private Const resxFilename As String = ".\CountryHeaders.resx"
     
   Public Sub Main()
      ' Create a resource file to read.
      CreateResourceFile()
      
      ' Enumerate the resources in the file.
      Dim rr As New ResXResourceReader(resxFilename)
      Dim dict As IDictionaryEnumerator = rr.GetEnumerator()
      Do While dict.MoveNext()
         Console.WriteLine("{0}: {1}", dict.Key, dict.Value)   
      Loop
   End Sub
   
   Private Sub CreateResourceFile()
      Dim rw As New ResxResourceWriter(resxFilename)
      Dim resNames() As String = {"Country", "Population", "Area", 
                                  "Capital", "LCity" }
      Dim columnHeaders() As String = { "Country Name", "Population (2010}", 
                                        "Area", "Capital", "Largest City" }
      Dim comments() As String = { "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 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

備註

方法 GetEnumerator 會擷取 XML 資源 (.resx) 數據流或字串中與目前 ResXResourceReader 對象相關聯的名稱/值組。 不過，如果在呼叫 之前將 UseResXDataNodes 屬性設定true為 ，則會將資源專案擷取為 ResXDataNodeGetEnumerator物件。 在此情況下，不論類型為何，都會傳回所有資源節點。
