<h1> Reflection Invoke Sample</h1>
|
|
|
|
|
|
<h2>Sample Overview</h2>
|
|
|
|
|
|
<p>This sample illustrates how to invoke different kinds of methods through
|
|
reflection. Because the names of the methods being invoked are stored in
|
|
strings, this mechanism provides the capability to specify methods to be invoked
|
|
at runtime, rather than at design-time, providing the scope to give your users
|
|
control over which particular method gets called. Although this sample focuses
|
|
on invoking methods, you can also set and get properties and fields, if
|
|
required.</p>
|
|
|
|
|
|
<p>In many coding scenarios, you know the task that you want to carry out before
|
|
you want to do it. Therefore, you can specify the methods that you need to
|
|
invoke, and the parameters you need to pass them. However, there are also
|
|
situations where you might want to dynamically invoke methods, based upon
|
|
specific scenarios, or user actions. This capability is available through the <b>
|
|
Reflection</b> namespace, by using the <b>InvokeMember</b> method on the <b>Type</b>
|
|
object. </p>
|
|
<p>See the sample source code for more detailed comments.</p>

<h2>Sample Source and Build Output Locations</h2>
|
|
|
|
|
|
<p>The sample source is found in sscli\samples\howto\reflection\invoke. </p>
|
|
|
|
|
|
<p>The source file is:</p>
|
|
|
|
|
|
<ul class="none">
|
|
<li><a href="reflectioninvoke.cs">reflectioninvoke.cs</a></li>
|
|
</ul>
|
|
|
|
|
|
<p>The build output location is %TARGETCOMPLUS%\samples\howto\reflection\invoke.
|
|
The output file is an executable assembly named reflectioninvoke.exe.</p>
|
|
|
|
|
|
<h2>Building the Sample</h2>
|
|
|
|
|
|
<p>All samples are built from the buildall script. </p>
|
|
|
|
|
|
<p>You can also build all the
|
|
samples by switching to the root of the sample directory, sscli\samples, and typing
|
|
<code>build -c</code>.</p>
|
|
|
|
|
|
<p>You can build this specific sample by switching to the sample directory and typing
|
|
<code>build -c</code>.</p>
|
|
|
|
|
|
<h2>Running the Sample</h2>
|
|
|
|
|
|
<p>These steps require that the Shared Source CLI (SSCLI) be already built and
|
|
functional.</p>
|
|
|
|
|
|
<ol>
|
|
<li>Run env.bat or source the env.csh or env.sh script files depending on
|
|
your platform.</li>
|
|
<li>Switch to the %TARGETCOMPLUS%\samples\howto\reflection\invoke directory.</li>
|
|
<li>Type the following command:<blockquote>
|
|
|
|
|
|
<p>clix reflectioninvoke.exe</p>
|
|
|
|
|
|
</blockquote>
|
|
|
|
|
|
</li>
|
|
</ol>
