Example
The following code example writes metadata to a blob.
| C# | Copy Code |
|---|---|
static void WriteBlobMetadata(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));
// Return a blob reference.
CloudBlob blob = new CloudBlob("mycontainer/myblob.txt", blobClient);
// Write some text to the blob.
blob.UploadText("this is a text blob");
// Define some metadata for the blob.
blob.Metadata["category"] = "images";
blob.Metadata["owner"] = "azureix";
// Write the metadata to the service.
blob.SetMetadata();
}

Remarks
The SetMetadata method writes the metadata values that are specified by the blob's Metadata property to the service. Note that setting the Metadata property sets metadata values on the blob reference only; you must call BeginSetMetadata or SetMetadata to write them to the service.
