Multi-dimensional vs. Jagged Arrays

[nooelan]

My model contains data that are multi-dimensional, and my first attempt was to implement this as a regular C# multidimensional array similar to this:

object[,] matrix3x3 = new object[3,3];

When trying to access this type of object from a template, Handlebars.Net threw an exception complaining it could not convert from object[ , ] to object[].

Then I changed my model implementation to jagged arrays (similar to this):

object[][] matrix3x3 = new object[3]; 
for (row = 0; row < 3; ++row)
    matrix3x3[row] = new object[3];

This works just fine with Handlebars.Net.

Question: Is the lack of support for regular multidimensional arrays intentional, or is it a missing feature or bug?

As regular, multidimensional arrays are more efficient, at least for 2D arrays according to C# guidelines, I think it is a good idea to add support for it. It will also help avoid having to change the implementation of an already existing model.

Hello @nooelan
Hamdlebars.Net is trying to keep feature parity with Handlebarsjs. Unfortunately multidimensional arrays are not supported in JavaScript and as a result would be never supported in Handlebarsjs.

You can provide your custom ObjectDescriptor that supports multidimensional arrays. However, you'd be only able to virtually project values to jagged array due to syntax limitations. Then usage will be something like this:

Value at [2,2]: {{array.2.2}}

Note: [1] is not an indexer syntax. It's rather way to specify non-valid entries (like words separated by space) in a correct way.
