# XQueryCompiler.DeclareNamespace Method

Declare a namespace for use by the query. This has the same status as a namespace appearing within the query prolog (though a declaration in the query prolog of the same prefix will take precedence)

public void DeclareNamespace(
string prefix,
string uri
);

#### Parameters

prefix
  The namespace prefix to be declared. Use a zero-length string to declare the default namespace (that is, the default namespace for elements and types).
uri
  The namespace URI. It is possible to specify a zero-length string to "undeclare" a namespace.
