CloudBlob.UploadText 方法 (String, Encoding, BlobRequestOptions)

Uploads a string of text to a block blob.

命名空間: Microsoft.WindowsAzure.StorageClient
組件: Microsoft.WindowsAzure.StorageClient (在 microsoft.windowsazure.storageclient.dll 中)

'用途
Dim instance As CloudBlob
Dim content As String
Dim encoding As Encoding
Dim options As BlobRequestOptions

instance.UploadText(content, encoding, options)

public virtual void UploadText (
	string content,
	Encoding encoding,
	BlobRequestOptions options
)
public void UploadText (
	String content, 
	Encoding encoding, 
	BlobRequestOptions options
)
public function UploadText (
	content : String, 
	encoding : Encoding, 
	options : BlobRequestOptions
)

參數

content

The text to upload.

encoding

An object that indicates the text encoding to use.

options

An object that specifies any additional options for the request.

The following code example writes to a blob using two different service clients.

static void UploadIfNotExist(Uri blobEndpoint, string accountName, string accountKey)
{
    //Create service client for credentialed access to the Blob service.
    CloudBlobClient blobClient = new CloudBlobClient(blobEndpoint, new StorageCredentialsAccountAndKey(accountName, accountKey));

    //Get a reference to the blob.
    CloudBlob blob = blobClient.GetBlobReference("mycontainer/myblob.txt");

    //Specify the if-none-match condition.
    BlobRequestOptions options = new BlobRequestOptions();
    options.AccessCondition = AccessCondition.IfNoneMatch("*");

    try
    {
        //Upload the blob only if it does not already exist.
        blob.UploadText("Upload this blob if it does not already exist.", Encoding.UTF8, options);
    }
    catch (StorageClientException e)
    {
        if (e.ErrorCode == StorageErrorCode.BlobAlreadyExists)
        {
            Console.WriteLine("Blob was not uploaded because it already exists.");
        }
        else
        {
            Console.WriteLine(e.Message);
        }
    }
}

任何這個類型的公用靜態 (在 Visual Basic 中為 Shared) 成員都具備執行緒安全。 並非所有的執行個體成員都是安全執行緒。
