XmlWriter.WriteValue Method (Object)
Writes the object value.
Assembly: System.Xml (in System.Xml.dll)
An invalid value was specified.
The value is null.
The writer is closed or in error state.
An XmlWriter method was called before a previous asynchronous operation finished. In this case, InvalidOperationException is thrown with the message “An asynchronous operation is already in progress.”
This method takes the common language runtime (CLR) object and converts the input value to the desired output type using the XML Schema definition language (XSD) data type conversion rules.
If the CLR object is a list type such as IEnumerable, IList, or ICollection, it is treated as an array of the value type. The XmlWriter converts the value to its string representations according to the XML Schema (XSD) data type rules and writes it out using the WriteString method.
If this method is called on an XmlWriter instance that outputs text-only, the typed value is serialized to text.

For the asynchronous version of this method, see WriteValueAsync.
