SharpSerializer 3.x

SharpSerializer is an open source XML and binary serializer for .NET. With only one line of code it can serialize types like: multidimensional array, nested array, array-of-arrays, polymorphic object (where value is inherited from the property type), generic type, generic listing (i.e. dictionary, collection) and many more...

SharpSerializer 3.x was ported from CodePlex to GitHub. It works with .NET Standard 1.0, .NET Framework 4.5.2 and above.

Runtime SharpSerializer requires a .NET platform implementing .NET Standard 1.0 or above.

According to the .NET Standard implementation support SharpSerializer works with:

  • .NET Core 1.0
  • .NET Framework 4.5 (with .NET Core 1.x or 2.0 SDK)
  • Mono 4.6
  • Xamarin.iOS 10.0
  • Xamarin.Mac 3.0
  • Xamarin.Android 7.0
  • Universal Windows Platform (UVP) 10.0
  • Windows 8.0
  • Windows Phone (WP) 8.1
  • Windows Phone Silverlight 8.0

For .NET Framework 4.5.2 (and above) and all .NET platforms implementing .NET Standard 1.3 there are additional API overloads providing not only serialization to a stream but also directly to a file by its name.


Using NuGet is recommended.

In Visual Studio open NuGet Package Manager and type-in: Install-Package SharpSerializer

In the Command Line (.NET CLI) use the dotnet command: dotnet add package SharpSerializer


var obj = CreateMyVerySophisticatedObject(); var serializer = new SharpSerializer(); serializer.Serialize(obj, "test.xml"); var obj2 = serializer.Deserialize("test.xml");

There are more usage examples on the tutorial page:

Usage Limitations

SharpSerializer serializes only public properties. If you like to serialize fields or private properties, they have to be wrapped in public properties.

SharpSerializer can deserialize only types providing public or private default constructor.

Please refer to the following article for a workaround:

Breaking Changes

Comparing to SharpSerializer 2.x

All platforms below .NET Framework 4.5 are no more supported.

Support for Portable Class Library (PCL) was depreciated. The following file is no more deployed: Polenter.SharpSerializer.Portable.dll

There are no breaking changes in the API in .NET Framework 4.5.2 and above.

There are no breaking changes in the API expected, if using PCL, however it's not thoroughly tested yet.

There are some tests concerning deploying and using SharpSerializer 3.x on different platforms, e.g. .NET Framework 4.5.2, .NET Core 1.0, 2.0 and Xamarin. More tests on different platforms are however appreciated.

Additional contributors are welcome. Just change source code, create unit tests and request a pull.
