Remarks

This class loader is used to load classes and resources from a search path of URLs referring to both JAR files and directories. Any URL that ends with a '/' is assumed to refer to a directory. Otherwise, the URL is assumed to refer to a JAR file which will be opened as needed.

The AccessControlContext of the thread that created the instance of URLClassLoader will be used when subsequently loading classes and resources.

The classes that are loaded are by default granted permission only to access the URLs specified when the URLClassLoader was created.

Constructors

URLClassLoader(IntPtr, JniHandleOwnership)	A constructor used when creating managed representations of JNI objects; called by the runtime.
URLClassLoader(URL[], ClassLoader, IURLStreamHandlerFactory)	Constructs a new URLClassLoader for the specified URLs, parent class loader, and URLStreamHandlerFactory.
URLClassLoader(URL[], ClassLoader)	Constructs a new URLClassLoader for the given URLs.
URLClassLoader(URL[])	Constructs a new URLClassLoader for the specified URLs using the default delegation parent `ClassLoader`.

Properties

Parent	Returns the parent class loader for delegation. (Inherited from ClassLoader)
PeerReference	(Inherited from Object)
ThresholdClass	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.
ThresholdType	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.

Methods
