Mapping XML Data Types to CLR Types

The following table describes the default mapping between the XML data types and the common language runtime (CLR) types.

Note

The xs and the xdt prefixes are mapped to the https://www.w3.org/2001/XMLSchema and the https://www.w3.org/2003/05/xpath-datatypes namespace URIs respectively.
