C#- using a variable in an 'enclosing' local scope?
<p>I am trying to add some new features to a C# application- in particular, trying to replicate some of its behavior, but inside a web browser, rather than in the application, as it currently is.</p>

<p>I am trying to call a method that has been defined in the <code>Browser.cs</code> class from inside a method in the <code>MainWindow.cs</code> class.</p>

<p>The method is defined in <code>Browser.cs</code> with:</p>

<pre><code>public partial class Browser : Form{
    public Browser(){
        ...
    }
    public void Browser_Load(object sender, EventArgs e){
        webKitBrowser1.Navigate("https://google.com");
    }
    ...
}
</code></pre>

<p>I am then trying to call it from <code>MainWindow.cs</code> as follows:</p>

<pre><code>public partial class MainWindow : Window{
    ...
    public MainWindow(){
        ...
        Browser mBrowser = new Browser();
        Object sender = new Object();
        EventArgs e = new EventArgs();
        mBrowser.Browser_Load(sender, e);
        ...
    }
    ...
}
</code></pre>

<p>But, I'm getting a compile error that says:</p>

<blockquote>
  <p>A local or parameter named 'e' cannot be declared in this scope because that name is used in an enclosing local scope to define a local or parameter</p>
</blockquote>

<p>What does this mean? I've never come across this error before- I am using the variable inside the same scope as where it has been declared- what does it mean by 'enclosing local scope'? Is that because I'm using <code>e</code> inside the parenthesis for the method call to <code>mBrowser.Browser_Load(sender, e)</code>?</p>

<p>Surely, since the call to this method is inside the same scope as where I've defined <code>e</code>, it shouldn't be an issue of scope?</p>

<p>I did try performing the call with:</p>

<pre><code>mBrowser.Browser_Load(sender, EventArgs e);
</code></pre>

<p>but this gave me a compile error saying:</p>

<blockquote>
  <p>'EventArgs' is a type, which is not valid in the given context.</p>
</blockquote>

<p>Can anyone point out what I'm doing wrong here, and what I should be doing to be able to call this method correctly?</p>
