how to set all attributes of an object a value

Hi,
 
Thank you for reaching out to JetBrains support.

1. Create the object using an empty object initializer:
   Persion p = new Persion { };
2. Place the cursor inside the braces { | }
3. Press Alt+Enter to access ReSharper’s actions menu
4. Select “Initialize members”.

If you'd like to separate the object creation from its member initialization, you can:

1. Select all the members inside { }.
2. Press Alt+Enter.
3. Select "Convert initializer to assignment."

I hope this helps. Please let me know if this solution doesn’t meet your goals.
