XmlResolver.ResolveUri Method

When overridden in a derived class, resolves the absolute URI from the base and relative URIs.

Namespace: System.Xml
Assembly: System.Xml (in system.xml.dll)

public virtual Uri ResolveUri (
	Uri baseUri,
	string relativeUri
public Uri ResolveUri (
	Uri baseUri, 
	String relativeUri
public function ResolveUri (
	baseUri : Uri, 
	relativeUri : String
) : Uri



The base URI used to resolve the relative URI


The URI to resolve. The URI can be absolute or relative. If absolute, this value effectively replaces the baseUri value. If relative, it combines with the baseUri to make an absolute URI.

Return Value

A Uri representing the absolute URI or a null reference (Nothing in Visual Basic) if the relative URI cannot be resolved.

Exception typeCondition


relativeUri is a null reference (Nothing in Visual Basic)

The absolute URI may be used as the base URI for any subsequent requests for entities that are relative to this URI.

See XmlUrlResolver.GetEntity for an example using this method.
