C# Understanding This IF Statement Logic

Question

Hi I have just used some code off a website for one of my classes in my C# project I dont really understand all of the logic behind it as i am new to coding with C#. I was wondering if someone was able to write this code in pseudo and also explain the logic behind it. string fullName = LastName; if (!string.IsNullOrWhiteSpace(FirstName)) { if (!string.IsNullOrWhiteSpace(fullName)) { fullName +=  ; } fullName += FirstName; } return fullName; Thank you

Details as follows- //First IF is checking that Text Vale of (FirstName) is Not Null or white Space //if this is true then it goes to second IF- if (!string.IsNullOrWhiteSpace(fullName)) //In Second If FullName is check that it should not have null or white space. //if this true then it add a comma into fullname which contains last name like fullName +=  ; //After that it added firstName to FullName which having LastName as above //After That both If Condition the Result comes from return fullName;

string fullName = LastName; // It checks FirstName value shouldn't be blank if (! string .IsNullOrWhiteSpace(FirstName)) { // It checks fullName value shouldn't be blank if (! string .IsNullOrWhiteSpace(fullName)) { // Appending comma to fullName which contains LastName value fullName +=   ; } // Appending FirstName to fullName fullName += FirstName; } // returns fullName return fullName; Example: LastName = Rayner FirstName = Luke Then it returns Rayner Luke
