Namespace: Microsoft.WindowsAzure.StorageClient
Assembly: Microsoft.WindowsAzure.StorageClient (in Microsoft.WindowsAzure.StorageClient.dll)

Usage

Visual Basic
Dim instance As CloudBlob Dim source As Stream Dim options As BlobRequestOptions Dim callback As AsyncCallback Dim state As Object Dim returnValue As IAsyncResult returnValue = instance.BeginUploadFromStream(source, options, callback, state)

Visual Basic

Dim instance As CloudBlob
Dim source As Stream
Dim options As BlobRequestOptions
Dim callback As AsyncCallback
Dim state As Object
Dim returnValue As IAsyncResult

returnValue = instance.BeginUploadFromStream(source, options, callback, state)

Syntax

Visual Basic
Public Overridable Function BeginUploadFromStream ( _ source As Stream, _ options As BlobRequestOptions, _ callback As AsyncCallback, _ state As Object _ ) As IAsyncResult

C#
public virtual IAsyncResult BeginUploadFromStream ( Stream source, BlobRequestOptions options, AsyncCallback callback, Object state )

C++
public: virtual IAsyncResult^ BeginUploadFromStream ( Stream^ source, BlobRequestOptions^ options, AsyncCallback^ callback, Object^ state )

Parameters

source

Type: System.IO.Stream

The stream providing the blob content.

options
