Interpolation in JSON string c#

Question

 Int32 unixTimestamp = (Int32)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds;
 Console.Write(unixTimestamp);
 var currentTimeUn = unixTimestamp.ToString();
string json = "{ \"Method\": \"GetShippedOrders\",\"Params\": { \"DateMin\": 1575158400, \"DateMax\": {currentTimeUn} }}";

How do I get currentTimeUn to be passed to DateMax?

Answer 1

Solution using String interpolation :

Int32 unixTimestamp = (Int32)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds;
var currentTimeUn = unixTimestamp.ToString();
string json = $"{{ \"Method\": \"GetShippedOrders\",\"Params\": {{ \"DateMin\": 1575158400, \"DateMax\": {currentTimeUn} }}}}";
Console.WriteLine(json);
