Creating Json file with C# of mysql data

around this issue I tried to create a json file of mysql database and it works with the code down below but i dont know how to give them a "header" that i need to fetch data from this json with volley in android studio i need: **this is only an example to let you know which section i need , i dont need "colors" ** , You can simply write a wrapper class like so.
public class ContainerClass {
    public List<students> Students {get;set;}
}
                var studentDetails = new ContainerClass();
                studentDetails.Students = ConvertDataTable<students>(ds.Tables[0]);

                JavaScriptSerializer js = new JavaScriptSerializer();
                return js.Serialize(studentDetails);

this one helps. pd.read_json takes a file path or a string buffer, so you can pass the json string directly to it.

Creating a JSON file from JSON response data in Python


Tag : python , By : Tom Berthon

Does that help I want to take the json response data from a REST request and create an actual json file. I tried something like this, but it did not work. Essentially, it just prints the headers. Any suggestions? , use the json module
my_data = json.loads(r.json())
# my_data is a dict mapping the JSON

with open(path, 'w') as f:
    json.dump(my_data, f)
json.dump(my_data, f, indent=2)
