Post array of strings to web API method

Question

this is my client side ajax call:

    var list = [\"a\", \"b\", \"c\", \"d\"];

    var jsonText = { data: list };

    $.ajax({
        type: \         


        

Answer 1

Setting the dataType won't help you.

This is how I do it :

var SizeSequence = {};
SizeSequence.Id = parseInt(document.querySelector("dd#Sequence_Id").textContent);
SizeSequence.IncludedSizes = [];
var sizes = document.querySelectorAll("table#IncludedElements td#Size_Name");
// skipping the first row (template)
for (var i = 1, l = sizes.length ; i != sizes.length ; SizeSequence.IncludedSizes.push(sizes[i++].textContent));

$.ajax("/api/SizeSequence/" + SizeSequence.Id, { 
     method: "POST",
     contentType: "application/json; charset=UTF-8",
     data: JSON.stringify(SizeSequence.IncludedSizes), 
...

The Server Part

// /api/SizeSequence/5
public async Task PostSaveSizeSequence(int? Id, List IncludedSizes)
    {
        if (Id == null || IncludedSizes == null || IncludedSizes.Exists( s => String.IsNullOrWhiteSpace(s)))
            return BadRequest();
        try
        {

            await this.Repo.SaveSizeSequenceAsync(Id.Value, IncludedSizes );
            return Ok();
        }
        catch ( Exception exc)
        {
            return Conflict();
        }
    }
