Parameters

blockId: Type: System.StringSystem::String^System.StringSystem.String
A Base64-encoded string that identifies the block.

blockData: Type: System.IO.StreamSystem.IO::Stream^System.IO.StreamSystem.IO.Stream
A Stream object that provides the data for the block.

contentMD5: Type: System.StringSystem::String^System.StringSystem.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.AccessConditionMicrosoft.WindowsAzure.Storage::AccessCondition^Microsoft.WindowsAzure.Storage.AccessConditionMicrosoft.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.BlobRequestOptionsMicrosoft.WindowsAzure.Storage.Blob::BlobRequestOptions^Microsoft.WindowsAzure.Storage.Blob.BlobRequestOptionsMicrosoft.WindowsAzure.Storage.Blob.BlobRequestOptions
A BlobRequestOptions object that specifies additional options for the request.

operationContext: Type: Microsoft.WindowsAzure.Storage.OperationContextMicrosoft.WindowsAzure.Storage::OperationContext^Microsoft.WindowsAzure.Storage.OperationContextMicrosoft.WindowsAzure.Storage.OperationContext
An OperationContext object that represents the context for the current operation.

callback: Type: System.AsyncCallbackSystem::AsyncCallback^System.AsyncCallbackSystem.AsyncCallback
An AsyncCallback delegate that will receive notification when the asynchronous operation completes.

state: Type: System.ObjectSystem::Object^System.ObjectSystem.Object
A user-defined object that will be passed to the callback delegate.

Return Value

Type: Microsoft.WindowsAzure.Storage.ICancellableAsyncResultMicrosoft.WindowsAzure.Storage::ICancellableAsyncResult^Microsoft.WindowsAzure.Storage.ICancellableAsyncResultMicrosoft.WindowsAzure.Storage.ICancellableAsyncResult

An ICancellableAsyncResult that references the asynchronous operation.

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. If the P:BlobRequestOptions.UseTransactionalMd5Referenced topic's target id should not be empty. Article id: 10e58d82-f416-477c-9d88-b673bf3a580c, link: 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.
