How to enumerate the names of all resources in a .resources file
Resources can be linked into assemblies using the assembly linker or Visual Studio and sometimes they can be compiled and stored in a resource file. To find out what you've got in the latter case you need to load the file and enumerate the name-value pairs that store the resource information. This is accomplished with the ResourceReader class that enables you to operate on .resources files. Listing 1 shows a simple application that demonstrates the use of the ResourceReader and the IDictionaryEnumerator it provides. In particular note how the handler for button 1 works, see button1_Click. Listing 1. using System; using System.Resources; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data;
