Public Class UploadStringCompletedEventArgs
	Inherits AsyncCompletedEventArgs

NameDescription
System_CAPS_pubpropertyCancelled

Gets a value indicating whether an asynchronous operation has been canceled.(Inherited from AsyncCompletedEventArgs.)

System_CAPS_pubpropertyError

Gets a value indicating which error occurred during an asynchronous operation.(Inherited from AsyncCompletedEventArgs.)

System_CAPS_pubpropertyResult

Gets the server reply to a string upload operation that is started by calling an UploadStringAsync method.

System_CAPS_pubpropertyUserState

Gets the unique identifier for the asynchronous task.(Inherited from AsyncCompletedEventArgs.)

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_protmethodRaiseExceptionIfNecessary()

Raises a user-supplied exception if an asynchronous operation failed.(Inherited from AsyncCompletedEventArgs.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

Instances of this class are passed to the UploadStringCompletedEventHandler.

The following code example demonstrates asynchronously uploading a string.

Public Shared Sub UploadStringInBackground2(ByVal address As String)

	Dim client As WebClient = New WebClient()
	Dim data As String = "Time = 12:00am temperature = 50"
	AddHandler client.UploadStringCompleted, AddressOf UploadStringCallback2
                      Dim uri as Uri = New Uri(address)
	client.UploadStringAsync(uri, data)
End Sub

The following method is called when the upload completes.

Private Shared Sub UploadStringCallback2(ByVal sender As Object, ByVal e As UploadStringCompletedEventArgs)
    Dim reply As String = CStr(e.Result)
    Console.WriteLine(reply)
End Sub
