The best advice I can give to a beginner programmer is to try to understand the basic rules of the language. Here in C# you need to ensure that any opening braces/brackets such as “{” or “(” are matched with closing ones such as “}” and “)”.
The compiler here is telling you the line (52) and column (2) where it expected a closing “}” but didn’t find it so look there and before it. Ensure they all match. Also, just searching for this error online will tell you the same thing so there should be no need for you to have to stop and wait on a post in a forum.
NOTE: You should always use code-tags when posting code and not plain text.
