Public Function GetEnumerator () As IDictionaryEnumerator

Returns

An enumerator for this ResourceReader object.

Examples

The example in this section uses the following .txt file named PatientForm.txt to define the resources used by an application.

Title="Top Pet Animal Clinic"
Label1="Patient Number:"
Label2="Pet Name:"
Label3="Species:"
Label4="Breed:"
Label5="Date of Birth:"
Label6="Age:"
Label7="Owner:"
Label8="Address:"
Label9="Home Phone:"
Label10="Work Phone:"
Label11="Mobile Phone:"

You can compile the .txt file into a .resources file by issuing the following command:

resgen PatientForm.txt

The following example enumerates the resources in PatientForm.resources and displays the name and value of each.

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

public class Example
{
   public static void Main()
   {
      var rr = new ResourceReader("PatientForm.resources");
      IDictionaryEnumerator dict = rr.GetEnumerator();
      int ctr = 0;

      while (dict.MoveNext()) {
         ctr++;
         Console.WriteLine("{0:00}: {1} = {2}", ctr, dict.Key, dict.Value);
      }

      rr.Close();
   }
}
// The example displays the following output:
//       01: Label3 = "Species:"
//       02: Label2 = "Pet Name:"
//       03: Label1 = "Patient Number:"
//       04: Label7 = "Owner:"
//       05: Label6 = "Age:"
//       06: Label5 = "Date of Birth:"
//       07: Label4 = "Breed:"
//       08: Label9 = "Home Phone:"
//       09: Label8 = "Address:"
//       10: Title = "Top Pet Animal Clinic"
//       11: Label10 = "Work Phone:"
//       12: Label11 = "Mobile Phone:"

Remarks

Typically, you enumerate resources by calling the GetEnumerator method and then repeatedly calling the MoveNext method on the returned IDictionaryEnumerator object until the method returns false. The resource name is available from the IDictionaryEnumerator.Key property; its value from the IDictionaryEnumerator.Value property. The example illustrates how to enumerate resources in this way.

The implementation of the IDictionaryEnumerator.Value property by the ResourceReader class can throw the following exceptions:

• FileNotFoundException

  The assembly that contains the type to which the data belongs cannot be found.

• FormatException

  The data is not in the expected format.

• TypeLoadException

  The type to which the data belongs cannot be found.

You can handle the exception by calling the GetResourceData method to retrieve information about the data type and the byte array assigned to the named resource. For more information, see the "Retrieving Resources by Name with GetResourceData" section in the ResourceReader class topic.
