How can I add a attribute to Root node of my XmlDocument() in C#

Question

I already have a XmlDocument object in C#. Let's say the InnerXml looks like this; ``` 8825 ``` How can I add a attribute which has the name as uuid and the value as 781283721381, e.g uuid="781283721381". So my Xml output would look like the following; ``` 8825 ```

Accepted Answer

```
document.DocumentElement.Attributes.Append(document.CreateAttribute("uuid")).Value = "12345"
```

Yeah, XmlDocument is a bit hard to modify, that's part of the reason why XDocument was invented. But it's the easiest to use XML serialization and work on objects.
