Converting a C# two-dimensional array into JavaScript formatting

Is there a more streamlined method for converting a two-dimensional array in C# like [[1, 2, 3],[4, 5, 6]] into a string representation "[[1, 2, 3],[4, 5, 6]]" without manually iterating through each value and formatting it?

I want to pass the array as an argument in my webView.ExecuteJavascript() function, which requires the method name string. Ideally, in C#, it would appear as:

webView.ExecuteJavascript("updateValues([[1, 2, 3],[4, 5, 6]])")

The updateValues function in JavaScript is defined as:

updateValues(newvalues) {
oldvalues = newvalues
}

Is there a more efficient way to achieve this task? Currently, the results are stored in a list of double arrays (List), and calling .ToArray().ToString(), like so:

webView.ExecuteJavascript("updateValues(" + gaugeCol.ToArray().ToString() + ")");

This only displays the variable type instead of the actual values.

Thank you

Answer №1

To convert various types of objects to JSON, you have the option to use either JavaScriptSerializer or Json.Net.

var arr = new[] { new[] { 1, 2, 3 }, new[] { 4, 5, 6 } };
string json = new JavaScriptSerializer().Serialize(arr); 
string json = JsonConvert.SerializeObject(arr);

These tools allow you to effectively convert almost any type of object into JSON format.

Answer №2

One way to convert a list of arrays into Javascript syntax is by using the following expression:

"[" + String.Join(",", gaugeCol.Select(gauge => "[" + String.Join(",", Array.ConvertAll(gauge, Convert.ToString)) + "]")) + "]"
