C#：这个语句是做什么的？ dynObj.@switch == 1？ 真假

Question

I recently took over some code and came a across a statement that I wasn't sure what it was doing so I decided to post it.

currCarbon.CleanGeneration = ( dynObj.@switch == 1? true: false);

Since 'dynObj' is a dynamic object holding a json value, is it checking if 'dynObj' contains a 'Switch' key / value?

Thanks for you help!

        dynamic dynObj = GetValues();

        if (dynObj != null) //json string from API
        {
          // Read the first record's carbon index
          var prevCarbon = _dbContext.WatttimeApilog.OrderByDescending(c => c.CreatedDate).FirstOrDefault();

          if (prevCarbon == null) //NO previous carbon value from database
          {
            //Plug in default values
            currCarbon.Percentage = defaultPercent;
            currCarbon.CleanGeneration = false;
            currCarbon.Rating = defaultRating;
            currCarbon.ValidUntil = DateTime.UtcNow;
            insertFlag = true;
          }
          else
          {
            currCarbon.Percentage = dynObj.percent;
            currCarbon.CleanGeneration = (dynObj.@switch == 1 ? true : false);
            currCarbon.Rating = Convert.ToByte(dynObj.rating);
            currCarbon.ValidUntil = dynObj.validUntil;
          }

It's setting CleanGeneration to true or false based on whether or not @switch is equal to one via a ternary operator.

EDIT: The code isn't the most clean and can be shortened to just currCarbon.CleanGeneration = dynObj.@switch == 1;

Linked is docs on the ternary operator: https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/operators/conditional-operator
