Serializing and deserializing data sample

This sample shows how to use the DataReader and DataWriter classes to store and retrieve data. Specifcially, this sample demonstrates the following scenarios:

  • Creating 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.
  • Opening 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 2015 to build and Windows 10 to execute.

To obtain information about Windows 10 development, go to the Windows Dev Center

To obtain information about Microsoft Visual Studio 2015 and the tools for developing Windows apps, go to Visual Studio 2015

Build the sample

  1. If you download the samples ZIP, be sure to unzip the entire archive, not just the folder with the sample you want to build.
  2. Start Microsoft Visual Studio 2015 and select File > Open > Project/Solution.
  3. Starting in the folder where you unzipped the samples, go to the Samples subfolder, then the subfolder for this specific sample, then the subfolder for your preferred language (C++, C#, or JavaScript). Double-click the Visual Studio 2015 Solution (.sln) file.
  4. Press Ctrl+Shift+B, or select Build > Build Solution.

Run the sample

The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.

Deploying the sample

  • Select Build > Deploy Solution.

Deploying and running the sample

  • To debug the sample and then run it, press F5 or select Debug > Start Debugging. To run the sample without debugging, press Ctrl+F5 or selectDebug > Start Without Debugging.
