Dapper custom type handlers to serialize/deserialize objects to Xml and Json. Can be also used to map GUID to a string.

Installation

Use NuGet Package Manager

Install-Package Dapper.CustomTypeHandlers

or .NET CLI

dotnet add package Dapper.CustomTypeHandlers

or just copy into the project file to reference the package

<PackageReference Include="Dapper.CustomTypeHandlers" Version="2.1.0" />

How to use

  • Create class that implements IXmlObjectType or IJsonObjectType interface
public class Book
{
	public long Id { get; set; }
	public string Title { get; set; }
	public BookDescription Description { get; set; }
}

public class BookDescription : IXmlObjectType
{
	public Learn Learn { get; set; }
	public string About { get; set; }
	public Features Features { get; set; }
}

public class Learn
{
	public List<string> Points { get; set; }
}

public class Features
{
	public List<string> Points { get; set; }
}
  • Register these new classes in Startup.cs
services.RegisterDapperCustomTypeHandlers(typeof(Book).Assembly);
  • Create table in a database that contains a column of the XML type (SQL Server)
CREATE TABLE [dbo].[Books](
	[Id] bigint IDENTITY(1,1) NOT NULL,
	[Title] nvarchar(200) NOT NULL,
	[Description] xml NULL
	CONSTRAINT [PK_Books] PRIMARY KEY CLUSTERED
	(
		[Id] ASC
	)
)

To persist object as a JSON, you can use the nvarchar field (class should implement IJsonObjectType)

CREATE TABLE [dbo].[Books](
	[Id] bigint IDENTITY(1,1) NOT NULL,
	[Title] nvarchar(200) NOT NULL,
	[Description] nvarchar(max) NULL
	CONSTRAINT [PK_Books] PRIMARY KEY CLUSTERED
	(
		[Id] ASC
	)
)
  • Use Dapper to save object data in the database
public async Task SaveBook(Book book)
{
	using (var conn = _connectionFactory.Connection())
	{
		await conn.ExecuteAsync(_@"INSERT INTO Books (Title, Description) VALUES (@Title, @Description)", book);
	}
}
