Serializing and deserializing data sample
Shows how to use the DataReader and DataWriter classes to store and retrieve data.
Note: This sample is part of a large collection of UWP feature samples. You can download this sample as a standalone ZIP file from docs.microsoft.com, or you can download the entire collection as a single ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.
Specifically, this sample shows how to:
- Create a memory-backed stream by using the InMemoryRandomAccessStream class and storing strings by using a DataWriter object. When the write operation completes, a DataReader object extracts the stored strings from the stream and displays them.
- Open a sequential-access stream over an image by using the OpenSequentialReadAsync and ReadBytes methods to retrieve and display its binary data.
Note The Windows universal samples require Visual Studio to build and Windows 10 to execute.
