Read a JSON property.

Parse a JSON document and dispose it after reading in C#.

using System;
using System.IO;
using System.Linq;
using System.Collections.Generic;
using System.Text.Json;

using var doc = JsonDocument.Parse("{\"name\":\"Ada\"}");
Console.WriteLine(doc.RootElement.GetProperty("name").GetString());

Expected output EXAMPLE

Ada

Details

Use Program.cs in a .NET 8 console project (dotnet new console --framework net8.0), then dotnet run. Uses only the .NET standard libraries.

Test inputs, results and environment

The exact published code ran in a dedicated Linux test container with prepared inputs. Unprivileged snippet process, external networking disabled, read-only root filesystem, and a fresh temporary working directory. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.
