title: How to specify example value for a parameter in C# XML doc comments?
body: <p>If you are using C# XML doc comments and you have a <code>param</code> to provide a description of a function parameter, how can you provide an example value (e.g. <code>&quot;San Francisco&quot;</code> or <code>5</code>)?</p>
  <p>Here is an example:</p>
  <pre><code>/// &lt;summary&gt;
  /// Lookup EAN barcode value, return product data
  /// &lt;/summary&gt;
  /// &lt;remarks&gt;Lookup an input EAN barcode and return key details about the product&lt;/remarks&gt;
  /// &lt;param name=&quot;value&quot;&gt;Barcode value&lt;/param&gt;
  /// &lt;returns&gt;JSON describing matching product data to the entered barcode&lt;/returns&gt;
  [HttpPost, Route(&quot;ean&quot;)]
  public BarcodeLookupResponse EanLookup([FromBody]string value)
  </code></pre>
  <p>Here, for the parameter named &quot;value&quot;, I would like to provide an example EAN barcode, e.g. &quot;QN1318481&quot; to document an example value (not an example code snippet)</p>
