JSON 字符串中的插值 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} }}";

如何將 currentTimeUn 傳遞給 DateMax？

Answer 1

使用字符串插值的解決方案：

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);

這是您一直在尋找的解決方案嗎？

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+"} }}";
