I am getting the user email id using below code in a MS Graph Api code:

user.Mail.Contains("John")

and also user DisplayName check using:

user.DisplayName.Contains("John")

I want Mail and DisplayName to be defined based on specific conditions and store it in a variable.

i.e

if(somecondition){
  searchCriteria="Mail";
}

else{
searchCriteria="DisplayName";
}

and then using interpolation:

user.${searchCriteria}.Contains("John")

But ,it doesn't work in this case.

Please Help.

You would need to use reflection to do this. – Jonathon Chase Feb 19 '20 at 21:54
Interpolation can only be used to create a string. It can't be used to get object properties like this. – Feb 19 '20 at 21:54
That's not string interpolation. That's sort of a dynamic property. Are you a PHP programmer? – Thomas Weller Feb 19 '20 at 21:54
@ThomasWeller No , i am using C# code. – AllTech Feb 20 '20 at 16:03
