C# Directory path to json formatting-CodePudding

I'm trying to save a folder path in a json file but I can't seem to find/figure out how to get it to parse it correctly

I'm using the following code to write the json file

string location = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
string userDataPreset = @"{UserData: [{Language: ""NL"", location: "   location   "}]}";
File.WriteAllText(userData, userDataPreset);

This creates the following json:

{
  "UserData": [
    {
      "Language": "NL",
      "location": C:\Users\stage\OneDrive\Documenten
    }
  ]
}

But I need it to become the following, with the double // and "":

{
  "UserData": [
    {
      "Language": "NL",
      "location": "C:\\Users\\stage\\OneDrive\\Documenten"
    }
  ]
}

What am I missing to parse this path correctly?

CodePudding user response：

to fix the string you can use an Escape method

location=Regex.Escape(location);

but the most relable method is to create an anonymous object and serialize it

    var data = new { UserData = new[] { new { Language = "NL", Location = location } } };
    var json = System.Text.Json.JsonSerializer.Serialize(data, new JsonSerializerOptions { WriteIndented = true});
    File.WriteAllText(userData, json);

json

{
  "UserData": [
    {
      "Language": "NL",
      "Location": "C:\\Users\\stage\\OneDrive\\Documenten"
    }
  ]
}
