The path of the resource file to be read.


The fileName parameter is null.

An I/O error has occurred.


The resource file has an invalid format. For example, the length of the file is zero.

The following code example defines a new instance of the ResourceReader class that will read from the specified file. The code then retrieves an enumerator, iterates through the file, and prints key/value pairs to the console.

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

public class ReadResources {

   public static void Main(string[] args) {

      // Opens a resource reader and gets an enumerator from it.
      IResourceReader reader = new ResourceReader("myResources.resources");
      IDictionaryEnumerator en = reader.GetEnumerator();

      // Goes through the enumerator, printing out the key and value pairs. 
      while (en.MoveNext()) {
         Console.WriteLine("Name: {0}", en.Key);
         Console.WriteLine("Value: {0}", en.Value);
