    copied!<p>I'm reading some <code>MethodInfo</code> from a proxy generated from a wsdl. </p> <p>One of the methods has three (<code>int</code>) parameters and a <code>int</code> return type, but when I explore the <code>ParameterInfo[]</code> I actually see eight parameters: </p> <ul> <li><code>Int32</code>, </li> <li><code>Boolean</code>, </li> <li><code>Int32</code>, </li> <li><code>Boolean</code>, </li> <li><code>Int32</code>, </li> <li><code>Boolean</code>, </li> <li><code>Int32&amp;</code>, </li> <li><code>Boolean&amp;</code></li> </ul> <p>Where do these extra parameters originate? </p> <p><strong>UPDATE</strong> </p> <p>To elaborate a bit more, the code in the generated proxy looks as following:</p> <pre><code> /// &lt;remarks/&gt; [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://tempuri.org/IInleerAppService/AddThreeNumbers", RequestNamespace="http://tempuri.org/", ResponseNamespace="http://tempuri.org/", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] public void AddThreeNumbers(int one, [System.Xml.Serialization.XmlIgnoreAttribute()] bool oneSpecified, int two, [System.Xml.Serialization.XmlIgnoreAttribute()] bool twoSpecified, int three, [System.Xml.Serialization.XmlIgnoreAttribute()] bool threeSpecified, out int AddThreeNumbersResult, [System.Xml.Serialization.XmlIgnoreAttribute()] out bool AddThreeNumbersResultSpecified) { object[] results = this.Invoke("AddThreeNumbers", new object[] { one, oneSpecified, two, twoSpecified, three, threeSpecified}); AddThreeNumbersResult = ((int)(results[0])); AddThreeNumbersResultSpecified = ((bool)(results[1])); } </code></pre> <p>Why is this? </p> <p>UPDATE</p> <p>If you're bugged by this, as I am, you cane easily avoid displaying those extra parameters by simply applying the following snippet of code:</p> <pre><code>if (!parameterInfo[i].Name.EndsWith("Specified") &amp;&amp; !parameterInfo[i].IsRetval &amp;&amp; !parameterInfo[i].Name.EndsWith("Result")) { // magic } </code></pre>
