<p> Expands all key values. </p>

<a href="ms-help://MS.NETFrameworkSDKv1.1/cpref/html/frlrfSystemVoidClassTopic.htm">void</a>ExpandKeyValues();</div>
<h4 class="dtH4">Remarks</h4>
<p> Calling this method expands all key values with the values of other keys. See the example below for more information. </p>
<h4 class="dtH4">Example</h4>
<p> In many cases you will find that your key values are dependent on the values of other keys. For instance you have a root path configuration value and several values for files that use this path like in this example: <pre class="code">[File Path]
RootPath = C:\Program Files\My Program
Logging = MyApp.log
WebPage = index.html
</pre> Without Nini if you wanted to combine the value of "RootPath" with "Logging" and "WebPage" then you would have to perform ugly string concatenations to get "C:\Program Files\My Program\index.html". In Nini you do not need to do this: <pre class="code">[File Path]
RootPath = C:\Program Files\My Program
Logging = ${RootPath}\MyApp.log
WebPage = ${RootPath}\index.html
</pre> This can save you a lot of trouble concatenating them yourself and make your code a lot cleaner. If you want to grab a value from a different section you can do the same above but add the section name followed by a bar ("|") like so: ${section|key}. </p>
