One solution, although it may not be ideal:
- Click and drag to mark the code you want to save.
- Use the Resharper "Surround with ..." command and select "
#region ". - Now you can collapse the code you want to save using the minus sign at the top of the new region.
- Remove the code surrounding
#region - Now click on the
#region heading again and select the Resharper option "Remove region / endregion directives".
Not an ideal solution, but it should help you get a better overview of what you are doing while working with larger blocks of code than your OP example.
It should look something like this (where the #region directive can hide any lines of code):
