DynamicIndex allows traversing .NET objects in a javascript like fashion. Sometimes you just need to be able to get navigate objects at runtime.

DynamicIndex is not currently on Nuget. It will be eventually. Open an issue if you need it now.

Using it is very simple:

You need one import:

using DynamicIndex

Assuming your object looks something like this:

var o = new Class1() 
{
    Int1 = 120,
    Int2 = -34,
    String1 = "Hello",
    String2 = "World",
    Array1 = [1, 2],
    Object1 = new Class2() 
    {
        Int1 = 4
    }
};

You first get a DynamicIndex object by calling the Index() extension method. Then you can use nested indexers to index the object. Finally, get the value out using Get().

For example:

// isValid1 = true
// val1 = 120
var isValid1 = o.Index()["Int1"].Get(out var val1);

// isValid2 = true
// val2 = 2
var isValid2 = o.Index()["Array1"][1].Get(out var val2);

// isValid3 = true
// val3 = 4
var isValid3 = o.Index()["Object1"]["Int1"].Get(out var val3);

If you know the type at compile time, you can strongly type Get():

var isValid = o.Index()["String1"].Get<string>(out var val); // val is type string, not object

In addition, the indexers are errorless. Get() will return false if any indexer keys and/or indices are not found.

var isValid = o.Index()["String100ThatDoesntExits"].Get(out var val); // returns false;
