Depending on condition insert list of object/ list of custom model in var in .net core-CodePudding

I have a condition where I am creating a payload with key value pair and depending of a condition the value will change. How can I achieve this without using dynamic as my data type?

dynamic finalList;
if(condition)
finalList = new List<object>() {...};
else
finalList = object.ExistingList;

I am consuming this finalList as a value in payload.

Placeholders = new Dictionary<string, object> {
  { "keyForList", finalList }
}

Is there any other way I can achieve above logic without using dynamic as my datatype for finalList as I don't know future challenges I might face for using it. Also, finalList might go under some further computation in future.

CodePudding user response：

Your dictionary is defined as Dictionary<string, object>. Use an object type instead of dynamic:

object finalList = condition 
  ? new List<object>() {...}
  : object.ExistingList;

However, I suspect the object.ExistingList is an IEnumerable. If so, then use the common interface for both lists:

IEnumerable<object> finalList = condition 
  ? new List<object>() {...}
  : object.ExistingList;
