NetCoreStack.ModelBinding
Model Binding library for .NET Core without HttpContext dependency
This library can be used for model binding without http request. A lot of the code was inspired from ASP.NET Core MVC but this is a complete (and a more lightweight) rewrite. I'll refer to this library as "Context free Model Binding".
Sample Models
public class Person
{
public string Name { get; set; }
public IList<Address> Addresses { get; set; }
}
public class Address
{
public int Zip { get; set; }
public string Street { get; set; }
public City City { get; set; }
}
public class City
{
public string Name { get; set; }
public float Latitude { get; set; }
public float Longitude { get; set; }
}Model Binding
var binder = IndexModelBinderHelper.GetIndexModelBinder();
var formCollection = new FormCollection(new Dictionary<string, StringValues>()
{
{ "Name", new [] { "NetCoreStack" } },
{ "Addresses.index", new [] { "Key1", "Key2" } },
{ "Addresses[Key1].Street", new [] { "Street1" } },
{ "Addresses[Key1].City.Name", new [] { "Yalova" } },
{ "Addresses[Key1].City.Latitude", new [] { "40.631281" } },
{ "Addresses[Key1].City.Longitude", new [] { "29.286804" } },
{ "Addresses[Key2].Street", new [] { "Street2" } },
});
var valueProviders = IndexModelBinderHelper.GetValueProviders(formCollection);
var parameter = new ParameterDescriptor()
{
Name = "parameter",
ParameterType = typeof(Person)
};
var modelState = new ModelStateDictionary();
// Act
var modelBindingResult = await binder.BindModelAsync(new CompositeValueProvider(valueProviders), modelState, parameter);
// Assert
Assert.True(modelBindingResult.IsModelSet);
Assert.IsType<Person>(modelBindingResult.Model);
