Call Excel Add-In function in macro
<p>I am developing Add-in for Excel 2013 and I have created a function in Excel Add-In as below</p>

<pre><code>  public string ExcelReturnString()
    {
        return "This is the string: hi";
    }
</code></pre>

<p>I have used below code to call the function, but it throws an error.</p>

<pre><code>Application.Run(ExcelReturnString)
</code></pre>

<p>How can I call the Add-in function in macro?</p>
