Methods

BeginLoad(Uri, Uri, AsyncCallback, Object)

Begins asynchronous loading of the provided targetUri.

Declaration

public IAsyncResult BeginLoad(Uri targetUri, Uri currentUri, AsyncCallback userCallback, object asyncState)

Parameters

Type	Name	Description
System.Uri	targetUri	A URI value to resolve and begin loading.
System.Uri	currentUri	The URI that is currently loaded.
System.AsyncCallback	userCallback	A callback function that will be called when this asynchronous request is ready to have EndLoad(IAsyncResult) called on it.
System.Object	asyncState	A custom state object that will be returned in System.IAsyncResult.AsyncState, to correlate between multiple async calls.

Returns

Type	Description
System.IAsyncResult	An System.IAsyncResult that can be passed to CancelLoad(IAsyncResult) at any time, or EndLoad(IAsyncResult) after the userCallback has been called.

CancelLoad(IAsyncResult)

Attempts to cancel a pending load operation.

Declaration

public void CancelLoad(IAsyncResult asyncResult)

Parameters

Type	Name	Description
System.IAsyncResult	asyncResult	The System.IAsyncResult returned from BeginLoad(Uri, Uri, AsyncCallback, Object) for the operation you wish to cancel.

Remarks

Cancellation is not guaranteed. Check the result from EndLoad to determine if cancellation was successful.

CanLoad(Uri, Uri)

Tells whether or not the target Uri can be loaded

Declaration

public bool CanLoad(Uri targetUri, Uri currentUri)

Parameters

Type	Name	Description
System.Uri	targetUri	A URI to load
System.Uri	currentUri	The current URI

Returns

Type	Description
System.Boolean	True if the targetURI can be loaded

EndLoad(IAsyncResult)

Completes the asynchronous loading of content

Declaration

public LoadResult EndLoad(IAsyncResult asyncResult)

Parameters

Type	Name	Description
System.IAsyncResult	asyncResult	The result returned from BeginLoad(Uri, Uri, AsyncCallback, Object), and passed in to the callback function.

Returns

Type	Description
LoadResult	The content loaded, or null if content was not loaded
