【解决方案1】：

you can try to deserialize the JSON string to a Dictionary<string, object>. then create another Dictionary. iterate over the first dictionary and add all the key-value pairs to the new dictionary why making the key to upper case using the ToUpper() method. then serialize the new dictionary to the JSON string.
