XmlResolver.GetEntity(Uri, String, Type) Method

Definition

When overridden in a derived class, maps a URI to an object that contains the actual resource.

public:
 abstract System::Object ^ GetEntity(Uri ^ absoluteUri, System::String ^ role, Type ^ ofObjectToReturn);
public abstract object? GetEntity (Uri absoluteUri, string? role, Type? ofObjectToReturn);
public abstract object GetEntity (Uri absoluteUri, string role, Type ofObjectToReturn);
abstract member GetEntity : Uri * string * Type -> obj
Public MustOverride Function GetEntity (absoluteUri As Uri, role As String, ofObjectToReturn As Type) As Object

Parameters

absoluteUri
Uri

The URI returned from ResolveUri(Uri, String).

role
String

Currently not used.

ofObjectToReturn
Type

The type of object to return. The current version only returns System.IO.Stream objects.

Returns

A stream object or null if a type other than stream is specified.

Exceptions

ofObjectToReturn is not a Stream type.

The specified URI is not an absolute URI.

absoluteUri is null.

There is a runtime error (for example, an interrupted server connection).

Examples

See XmlUrlResolver.GetEntity for an example using this method.

Remarks

This method is used when the caller wants to map a given URI into the object containing the actual resource that the URI represents. The type of object returned is negotiable; however, the implementation must always support System.IO.Stream.

For the asynchronous version of this method, see GetEntityAsync.

Important

Your application can mitigate memory denial of service threats to the GetEntity method by implementing an IStream that limits the number of bytes read. This helps guard against situations where malicious code attempts to pass an infinite stream of bytes to the GetEntity method.
