PutBlock(String, Stream, Checksum, AccessCondition, BlobRequestOptions, OperationContext)

Uploads a single block.

[Microsoft.Azure.Storage.DoesServiceRequest]
public virtual void PutBlock (string blockId, System.IO.Stream blockData, Microsoft.Azure.Storage.Shared.Protocol.Checksum contentChecksum, Microsoft.Azure.Storage.AccessCondition accessCondition = default, Microsoft.Azure.Storage.Blob.BlobRequestOptions options = default, Microsoft.Azure.Storage.OperationContext operationContext = default);

Public Overridable Sub PutBlock (blockId As String, blockData As Stream, contentChecksum As Checksum, Optional accessCondition As AccessCondition = Nothing, Optional options As BlobRequestOptions = Nothing, Optional operationContext As OperationContext = Nothing)

Parameters

blockId

String

A Base64-encoded string that identifies the block.

blockData

Stream

A Stream object that provides the data for the block.

contentChecksum

Checksum

A hash value used to ensure transactional integrity. May be null or Checksum.None

accessCondition

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

BlobRequestOptions

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

operationContext

OperationContext

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

Attributes

DoesServiceRequestAttribute

Remarks

Clients may send the content checksum headers for a given operation as a means to ensure transactional integrity over the wire. The contentChecksum parameter permits clients who already have access to a pre-computed checksum value for a given byte range to provide it. If the BlobRequestOptions.UseTransactionalMd5 or BlobRequestOptions.UseTransactionalCrc64 properties are set to true and the corresponding content parameter is set to null, then the client library will calculate the checksum value internally.

PutBlock(String, Uri, Nullable<Int64>, Nullable<Int64>, Checksum, AccessCondition, BlobRequestOptions, OperationContext)

Uploads a single block, copying from a source URI.

Nullable<Int64>

The byte offset at which to begin returning content.

count

Nullable<Int64>

The number of bytes to return, or null to return all bytes through the end of the blob.

contentChecksum

Checksum

A hash value used to ensure transactional integrity. May be null or Checksum.None

contentMD5

String

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

accessCondition

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

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

Attributes

DoesServiceRequestAttribute

Remarks

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.
