Answer 1

You can use object. Below is the basic example:-

Dictionary<string, object> storage = new Dictionary<string,object>();

storage.Add("age", 12);
storage.Add("name", "test");
storage.Add("bmi", 24.1);

int a = (int)storage["age"];
string b = (string)storage["name"];
double c = (double)storage["bmi"];

Answer 2

You can use object:

var serializeMetadata = new Dictionary<string, object>();
