CloudBlockBlob.PutBlock Method (String, Stream, String, AccessCondition, BlobRequestOptions, OperationContext)

 

Updated: July 12, 2016

Uploads a single block.

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

[DoesServiceRequestAttribute]
public virtual void PutBlock(
	string blockId,
	Stream blockData,
	string contentMD5,
	AccessCondition accessCondition = null,
	BlobRequestOptions options = null,
	OperationContext operationContext = null
)

Parameters

blockId
Type: System.String

A Base64-encoded string that identifies the block.

blockData
Type: System.IO.Stream

A Stream object that provides the data for the block.

contentMD5
Type: System.String

An optional hash value used to ensure transactional integrity for the block. May be null or an empty string.

accessCondition
Type: Microsoft.WindowsAzure.Storage.AccessCondition

An AccessCondition object that represents the condition that must be met in order for the request to proceed. If null, no condition is used.

options
Type: Microsoft.WindowsAzure.Storage.Blob.BlobRequestOptions

A BlobRequestOptions object that specifies additional options for the request. If null, default options are applied to the request.

operationContext
Type: Microsoft.WindowsAzure.Storage.OperationContext

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

Clients may send the Content-MD5 header for a given Put Block operation as a means to ensure transactional integrity over the wire. The contentMD5 parameter permits clients who already have access to a pre-computed MD5 value for a given byte range to provide it. If the P:BlobRequestOptions.UseTransactionalMd5 property is set to true and the contentMD5 parameter is set to null, then the client library will calculate the MD5 value internally.
