After copy and paste the "Hello from the comic books control" to the ContentResult(), why not have a semicolon after it? and why is there a semicolon after the curly braces?

Generally, semicolons only go after statements.
The braces after new ContentResult() enclose a list of initial object properties, and since there is only one no punctuation is needed. If the list had included additional properties, they would have been separated by commas.
The entire expression is part of a return statement, so after the closing brace a semicolon is used to indicate the end of that statement.

ContentResult("XXX", "YYY") would be passing values into the constructor for the ContentResult class and ContentResult() {Content = "XXX", ContentEncoding = "YYY"} is assigning values to the properties of the ContentResult. As Steven mentioned you were setting multiple properties then they are comma separated but if there's only 1 value being set then you can skip the comma.

4,374 PointsThanks for your help, I got why there is a semicolon after the brace of return, but I'm still a little confused about why there is no semicolon after Content = "Hello from the comic books controller"... is it like declaring something in this way? : ContentResult a = new ContentResult("Hello from the comic books controller")? I could write ContentResult() {Content = "XXX", ContentEncoding = "YYY"} just like something like ContentResult("XXX", "YYY")?
