C# check if handler is present in Web.Config-CodePudding

In my Web.Config file I have the following:

<system.webServer>
  <handlers>
    <add name="HANDLERNAME" verb="*" path="PATH.axd" type="HANDLERTYPE">
  </handlers>
</system.webServer>

Before I run a particular bit of code, I want to check to see if the handler is present in my Web.Config file.

Is this something I'm able to do?

I've tried: ConfigurationManager.GetSection("system.webServer/handlers") with no success, as this returns null.

Any help would be greatly appreciated!

I found two way to check for the handlers in the web.config

    XmlDocument doc = new XmlDocument();
    doc.Load(path); *//path is the location of the web.config file*

    XmlElement root = doc.DocumentElement;
    XmlNode nodes = root.SelectSingleNode("/system.webServer");
    XmlNodeList childnotes = nodes.ChildNodes;
    bool isExist = false;;
    foreach (XmlNode node in childnotes)
    {
        if (node.Name.Contains("handlers"))
        {
            isExist = node.OuterXml.Contains("HANDLERNAME");
        }
    }

you can check the value of isExist

The other way is to get entire web.config as a string and check if it contains HANDLERNAME
