This method retrieves a 64-bit unsigned integer value from the root node of the System.Xml.XmlNodeReader.
It's a fundamental operation often used for data manipulation and parsing.
The method takes no arguments.
It returns the value as a 64-bit unsigned integer.
Let's say the root node of the XML has a value of 42. `ReadUInt64(rootNode)` would return 42.
- Data validation: Ensuring values fall within a specific range. - Parsing: Extracting numeric data from XML structures. - Data conversion: Converting XML to other data types.
Refer to the System.Xml.XmlNodeReader.ReadUInt64 documentation for detailed information.
