JsonPathToModel 1.2.2

JsonPathToModel

Use JSONPath to navigate through .NET in-memory models

DI registration:

// program
...
    services.AddJsonPathToModel(options => 
                { 
                    options.OptimizeWithCodeEmitter = true;
                });
...

// constructor
public void MyService(IJsonPathModelNavigator navigator)
...

Usage:

var model = new SampleModel
{
    Id = "7",
    Name = "Gerry",
    Nested = new([new SampleNested { Id = "xyz", Name = "Pedro" }])
};

var navi = new JsonPathModelNavigator();

var resultSingle = navi.GetValue(model, "$.Id");
navi.GetValue(model, "$.Nested[0].Name");

var resultValues = navi.SelectValues(model, "$.Nested[*].Id");
navi.SelectValues(model, "$.Nested[*].Name");

var result = navi.SetValue(model, "$.Nested[0].Name", "Abdula");

Model:

public class SampleModel
{
    public string Id { get; set; } 
    public string Name { get; set; }
    public List<SampleNested> Nested { get; set; } = [];
}

public class SampleNested
{
    public string Id { get; set; }
    public string Name { get; set; }
}
