c# object reference not set to an instance of an application

I'm trying to populate data from an xml database but I keep getting an error. My form_load calls loadplayer.

Code:

       private void LoadPlayerData()
        {
            try
            {
                XmlDocument doc = new XmlDocument();
                doc.Load(xmlloc);
                XmlNode node = null;
               
                
                node = doc.SelectSingleNode("//player[@name='" + comboBox1.Text + "']");
             catch(Exeption ex)
             {
                      MessageBox.Show(ex.message);
             }

This is throwing the error "object reference not set to an instance of an application". I can't go: XmlNode node = new XmlNode(); so I dont no how to get around this.

 

Ya problem solved, I had the wrong xml file loading haha

 

if you're going to have a lot of R/W's to that file, you might consider a read write lock:

Thanks, I was looking for something like that.
