How can cast the string to json using C#?

One string like this：

[["0.45842413","10"],["0.45850028","11"],["0.46092215","10"],["0.478999","133.69218728"]]


after cast like this:

[["Price":"0.45842413","Amount":"10"],["Price":"0.45850028","Amount":"11"],["Price":"0.46092215","Amount":"10"],["Price":"0.478999","Amount":"133.69218728"]]

Your question is unclear, both strings are JSON
You're basically asking how to cast from one format of JSON to another.
The best way to do it would be to

You could use Regex.Replace with capture groups to insert "Price" and "Amount" into your string.

Regex.Replace

Something like:

using System;
using System.Text.RegularExpressions;

public class Program
{
public static void Main()
{
string data = "[["0.45842413","10"],["0.45850028","11"],["0.46092215","10"],["0.478999","133.69218728"]]";
data = Regex.Replace(data, "("\d+[.]{0,1}\d{0,}"),("\d+[.]{0,1}\d{0,}")", ""Price":$1,"Amount":$2");
Console.WriteLine(data);
}
}


Result:

[["Price":"0.45842413","Amount":"10"],["Price":"0.45850028","Amount":"11"],["Price":"0.46092215","Amount":"10"],["Price":"0.478999","Amount":"133.69218728"]]
