XmlResolver::GetEntity Method (Uri^, String^, Type^)
When overridden in a derived class, maps a URI to an object that contains the actual resource.
Assembly: System.Xml (in System.Xml.dll)
public: virtual Object^ GetEntity( Uri^ absoluteUri, String^ role, Type^ ofObjectToReturn ) abstract
Parameters
- absoluteUri
-
Type:
System::Uri^
The URI returned from ResolveUri.
- role
-
Type:
System::String^
Currently not used.
- ofObjectToReturn
-
Type:
System::Type^
The type of object to return. The current version only returns System.IO.Stream objects.
| Exception | Condition |
|---|---|
| XmlException | ofObjectToReturn is not a Stream type. |
| UriFormatException | The specified URI is not an absolute URI. |
| ArgumentNullException | absoluteUri is null. |
| Exception | There is a runtime error (for example, an interrupted server connection). |
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.
Security Note
|
|---|
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. |
See XmlUrlResolver::GetEntity for an example using this method.
