Dictionary <-> JSON

[softwarejaeger]

Hello, is there any possible and simple way to convert a Dictionary to a JSON-String an of course to convert it in the other direction (JSON-String to Dictionary)? I've searched a lot, but i havent't found a simple solution. Thank you

You can use Json.NET[^] for the same. However, I have found one class which converts Dictionary to String that might help you.

class ConvertDictionary
{
Dictionary<string, int> _dictionary = new Dictionary<string, int>()
{
{"salmon", 5},
{"tuna", 6},
{"clam", 2},
{"asparagus", 3}
};

public ConvertDictionary()
{
    // Convert dictionary to string and save
    string s = GetLine(\_dictionary);
    File.WriteAllText("dict.txt", s);
    // Get dictionary from that file
    Dictionary<string, int> d = GetDict("dict.txt");
}

string GetLine(Dictionary<string, int> d)
{
    // Build up each line one-by-one and them trim the end
    StringBuilder builder = new StringBuilder();
    foreach (KeyValuePair<string, int> pair in d)
    {
        builder.Append(pair.Key).Append(":").Append(pair.Value).Append(',');
    }
    string result = builder.ToString();
    // Remove the final delimiter
    result = result.TrimEnd(',');
    return result;
}

Dictionary<string, int> GetDict(string f)
{
    Dictionary<string, int> d = new Dictionary<string, int>();
    string s = File.ReadAllText(f);
    // Divide all pairs (remove empty strings)
    string\[\] tokens = s.Split(new char\[\] { ':', ',' },
        StringSplitOptions.RemoveEmptyEntries);
    // Walk through each item
    for (int i = 0; i < tokens.Length; i += 2)
    {
        string name = tokens\[i\];
        string freq = tokens\[i + 1\];

        // Parse the int (this can throw)
        int count = int.Parse(freq);
        // Fill the value in the sorted dictionary
        if (d.ContainsKey(name))
        {
            d\[name\] += count;
        }
        else
        {
            d.Add(name, count);
        }
    }
    return d;
}

}
