NSDictionary to Json in Xamarin.iOS - xamarin

Question

I am trying to convert the NSDictionary into Json using NSJsonSerialization.Serialize. But i am not getting expected output
Code in Xamarin.iOS
var dictionary = new NSDictionary(
new NSString("userName"), new NSString("450012"),
new NSString("password"), new NSString("Abc134"),
new NSString("companyId"), new NSString("CM1")
);
request.Body = NSJsonSerialization.Serialize(dictionary, 0, out error);
the problem is that value of dictionary variable is showing
{{password":Abc134,companyId:CM1,userName:450012}}
instead of
{password:Abc134,companyId:CM1,userName:450012}
it is adding one curly braces at the front and back
is there any way to generate proper json string for user input values

Answer 1

There's nothing wrong with your json. If you print it in the console you will see that the value being printed is the value you expect.
{"password":"Abc134","companyId":"CM1","userName":"450012"}
Give it a try with:
Console.WriteLine($"{json}");
If you really, really want to get rid of of that "extra" curly braces just convert the result into string.
var jsonString = json.ToString();
The above should do the work.
I would just suggest you changing your method to this:
var json2 = NSJsonSerialization.Serialize(dictionary, NSJsonWritingOptions.PrettyPrinted, out error);
Using the PrettyPrinted option.
Hope this helps.-

Yes, you can try to create a custom object to serialize. Create a simple plain object to hold the data you want.
User user = new User() {
UserName = "JohnDoe",
Password = "xxx",
CompanyId = 01
};
request.Body = NSJsonSerialization.Serialize(user, 0, out error);
Then serialize it and you will see the proper json well formed.
