在C＃中转换JSON格式

Question

我有一个Json格式

pi@raspberrypi:~/crash_dumps $ lldb-4.0 $(which dotnet) --core ./core.dotnet.1402.raspberrypi.1533274692
(lldb) target create "/usr/local/bin/dotnet" --core "./core.dotnet.1402.raspberrypi.1533274692"
Core file '/home/pi/crash_dumps/./core.dotnet.1402.raspberrypi.1533274692' (arm) was loaded.
(lldb) plugin load /opt/dotnet/shared/Microsoft.NETCore.App/2.1.1/libsosplugin.so
(lldb) setclrpath /opt/dotnet/shared/Microsoft.NETCore.App/2.1.1
(lldb) sos PrintException
(lldb)
Stack dump:
0.      HandleCommand(command = "")
Segmentation fault (core dumped)

但是我只想获得strHTML = {"responseCode":"3001","response":"1533352425185"} 如何在asp.net中获得它？
