Requests that the service start to copy a blob's contents, properties, and metadata to a new blob.

Namespace: Microsoft.WindowsAzure.Storage.Blob
Assembly: Microsoft.WindowsAzure.Storage (in Microsoft.WindowsAzure.Storage.dll)

Usage

Visual Basic
Dim instance As CloudBlockBlob Dim source As Uri Dim sourceAccessCondition As AccessCondition Dim destAccessCondition As AccessCondition Dim options As BlobRequestOptions Dim operationContext As OperationContext Dim returnValue As IAsyncOperation(Of String) returnValue = instance.StartCopyFromBlobAsync(source, sourceAccessCondition, destAccessCondition, options, operationContext)

Visual Basic

Dim instance As CloudBlockBlob
Dim source As Uri
Dim sourceAccessCondition As AccessCondition
Dim destAccessCondition As AccessCondition
Dim options As BlobRequestOptions
Dim operationContext As OperationContext
Dim returnValue As IAsyncOperation(Of String)

returnValue = instance.StartCopyFromBlobAsync(source, sourceAccessCondition, destAccessCondition, options, operationContext)

JScript
DefaultOverloadAttribute public function StartCopyFromBlobAsync ( source : Uri, sourceAccessCondition : AccessCondition, destAccessCondition : AccessCondition, options : BlobRequestOptions, operationContext : OperationContext ) : IAsyncOperation<String>

JScript

DefaultOverloadAttribute 
public function StartCopyFromBlobAsync (
	source : Uri, 
	sourceAccessCondition : AccessCondition, 
	destAccessCondition : AccessCondition, 
	options : BlobRequestOptions, 
	operationContext : OperationContext
) : IAsyncOperation<String>

Parameters

source: The URI of a source blob.

sourceAccessCondition: An object that represents the access conditions for the source blob. If null, no condition is used.

destAccessCondition: An object that represents the access conditions for the destination blob. If null, no condition is used.

options: A BlobRequestOptions object that specifies additional options for the request.

operationContext: An OperationContext object that represents the context for the current operation.

Return Value

The copy ID associated with the copy operation.

Remarks

This method fetches the blob's ETag, last modified time, and part of the copy state. The copy ID and copy status fields are fetched, and the rest of the copy state is cleared.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
