Examples

The File Access sample shows you how to use a StorageStreamTransaction object to perform a transacted write operation on a file.

try
{
    if (file != null)
    {
        using (StorageStreamTransaction transaction = await file.OpenTransactedWriteAsync())
        {
            using (DataWriter dataWriter = new DataWriter(transaction.Stream))
            {
                dataWriter.WriteString("Swift as a shadow");
                transaction.Stream.Size = await dataWriter.StoreAsync(); // reset stream size to override the file
                await transaction.CommitAsync();
            }
        }
    }
}
// Use catch blocks to handle errors
catch (FileNotFoundException)
{
    // For example, handle a file not found error
}

In the example, file is a local variable that contains a storageFile that represents the file to write.
