It actually doesn't matter how many of the ';' character there are, it represents a code-escape to the compiler, so having multiple ';' will still compile.

However, not having a ';' as you see, will cause it to throw errors

Here's a tip, if you want to keep your code tidy (when word wrapping is off), whitespace is pretty much completely removed at compile time, so the code below would still compile;

public class MyClass
{
        public MyClass()
        { }

        public override void ToString()
        {
                return String.Format("Type: {0} | HashCode: {1}",

                           this.GetType().FullName,
                    this.GetHashCode()
                );
        }
}

Which would end up compiling into;

public class MyClass{public MyClass(){}public override void ToString(){return String.Format("Type: {0} | HashCode: {1:X8}",this.GetType().FullName,this.GetHashCode());}}
