Parameters

pageData: Type: System.IO.StreamSystem.IO::Stream^System.IO.StreamSystem.IO.Stream
A Stream object providing the page data.

startOffset: Type: System.Int64System::Int64System.Int64System.Int64
The offset at which to begin writing, in bytes. The offset must be a multiple of 512.

contentMD5: Type: System.StringSystem::String^System.StringSystem.String
An optional hash value used to ensure transactional integrity for the page. 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.

cancellationToken: Type: System.Threading.CancellationTokenSystem.Threading::CancellationTokenSystem.Threading.CancellationTokenSystem.Threading.CancellationToken
A CancellationToken to observe while waiting for a task to complete.

Return Value

Type: System.Threading.Tasks.TaskSystem.Threading.Tasks::Task^System.Threading.Tasks.TaskSystem.Threading.Tasks.Task

A Task object that represents the asynchronous operation.

Remarks

Clients may send the Content-MD5 header for a given Write Pages 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: ad21a784-cd8f-41a0-96a0-9e5c54be39c6, 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.
