Exceptions in C# vs Java [duplicate]

I am currently moving from Java to C#. While connecting the dots on comparison between the two I came across Exceptions.

As in Java, you must either handle an exception or mark the method as one that may throw it using the throws keyword. I have not been able to find any such way of marking methods in C#.

void show() throws Exception { throw new Exception("my.own.Exception"); } 

So the question is simple how can I achieve such java like exception throwing in C#, that is what would be equivalent to the above code in C#.
