I'd written some time earlier and need to remember the type and initialized value for PersonId, I know where to look. I can look at the top of the code block much faster than I can pull up and use a search tool.

The problem with comments is that they are often not changed in sync with code updates. Another one is that meaningful comment today is often meaningless tomorrow. I am trying my best creating meaningful comments and this is an art and continuous learning

and despite best efforts issues with code comments are missed even by best reviewers.

1. Strip out all code within blocks (except block delimiters - i.e. if, do, for, while and switch code boundaries).
2. The remaining code and comments should clearly represent the method's psuedocode.  If it doesn't, you need to add comments.

/// <summary>
/// Performs a file copy (a better comment is required here).
/// </summary>
/// <returns>The result of the operation.</returns>
private MyClass MyMethod()
{
    // For each file whose name is less than 21 chars...
    int count = 0;
    foreach (MyFileObj file in _myFileCollection) {
        if (file.Name.Length <= 20) {
            // Copy it to the new location
            file.CopyTo(@"C:\SomePath\" + file.Name);
            count++;
        }
    }
 
    // A lot of other code
    // ...

    // Return result
    MyClass someObj = new MyClass();
    someObj.FileCount = count;
    return someObj;
}

// an add method to add two integers
    // add the two integers and return the result

// an add method to add two integers
-(int)add: (int)a b:(int)b
{
    // add the two integers and return the result
    return a+b;
}

What were they thinking when they wrote this piece of code?
