BlobRequestOptions that you specify.
Namespace: Microsoft.WindowsAzure.StorageClient
Assembly: Microsoft.WindowsAzure.StorageClient (in Microsoft.WindowsAzure.StorageClient.dll)
Usage
| Visual Basic |
|---|
Dim instance As CloudBlob
Dim fileName As String
Dim options As BlobRequestOptions
instance.UploadFile(fileName, options) |
Syntax
| Visual Basic |
|---|
Public Overridable Sub UploadFile ( _
fileName As String, _
options As BlobRequestOptions _
) |
| C# |
|---|
public virtual void UploadFile (
string fileName,
BlobRequestOptions options
) |
| C++ |
|---|
public:
virtual void UploadFile (
String^ fileName,
BlobRequestOptions^ options
) |
Parameters
- fileName
Type: System.String
The path and file name of the file to upload.
- options
Type: Microsoft.WindowsAzure.StorageClient.BlobRequestOptions
An object that specifies any additional options for the request.
Example
The following code example uploads a file from the local computer to a blob, using the specified blob request options.
| C# |  Copy Code |
|---|
static void UploadBlobFromFile(Uri blobEndpoint, string accountName, string accountKey)
{
// Create a service client for credentialed-access to the blob.
CloudBlobClient blobClient =
new CloudBlobClient(blobEndpoint,
new StorageCredentialsAccountAndKey(accountName, accountKey));
// Get a reference to a container, which may or may not already exist in the cloud.
CloudBlobContainer container = blobClient.GetContainerReference("mycontainer");
// Create a new container in the cloud if one with this container address does not already exist.
container.CreateIfNotExist();
// Get a reference to a blob, which may or may not exist.
CloudBlob blob = container.GetBlobReference("myfile.txt");
// Create a BlobRequestOptions object.
BlobRequestOptions options = new BlobRequestOptions();
// Use the BlobRequestOptions object to set options for the request.
// E.g., Specify a retry policy of 10 retries.
options.RetryPolicy =
RetryPolicies.RetryExponential(10, RetryPolicies.DefaultClientBackoff);
// Upload content to the blob, which will create the blob if it does not already exist.
// If the operation fails, try it again - up to ten retries before giving up.
blob.UploadFile("c:\\myfile.txt", options);
}
