Extensions for System.Text.Json.
Add the O9d.Json.Formatting package from NuGet
dotnet add package O9d.Json.Formatting
If you want to use a pre-release package, you can download them GitHub packages.
This O9d.Json.Formatting library adds support for snake_case formatting to System.Text.Json which is still missing. The included implementation originates from the Newtonsoft.Json project.
To configure snake case formatting when using JsonSerializer directly:
var options = new JsonSerializerOptions()
{
PropertyNamingPolicy = new JsonSnakeCaseNamingPolicy()
};
string json = JsonSerializer.Serialize(someObj, options);To configure snake case formatting in an ASP.NET Core MVC project:
services.AddControllers()
.AddJsonOptions(options =>
{
options.JsonSerializerOptions.PropertyNamingPolicy = new JsonSnakeCaseNamingPolicy()
});Or in ASP.NET 6.0 Minimal APIs:
builder.Services.Configure<JsonOptions>(options =>
{
options.SerializerOptions.PropertyNamingPolicy = new JsonSnakeCaseNamingPolicy());
});Pre-release packages can be downloaded from GitHub Packages.
dotnet add package O9d.Json.Formatting --prerelease --source https://nuget.pkg.github.com/benfoster/index.json
