I need to validate the contents of a C# method.

I do not care about syntax errors that do not affect the method's scope.

I do care about characters that will invalidate parsing of the rest of the code. For example:

method()
{
  /* valid comment */
  /*           <-- bad
  for (i..) {
  } 
  for (i..) {  <-- bad
}

I need to validate/fix any non-paired characters.

This includeds /* */, { }, and maybe others.

How should I go about this?

My first thought was Regex, but that clearly isn't going to get the job done.
