Slight Code Refactoring (#4373)

* Simplify return statements by using ternary expressions

* Remove a redundant type conversion

* Reduce nesting by inverting "if" statements

* Try to improve code readability by using LINQ and inverting "if" statements

* Try to improve code readability by using LINQ, using ternary expressions, and inverting "if" statements

* Add line breaks to long LINQ
