# Simplify debugging with DebuggerDisplay attribute in .NET

**[Code4IT](https://daily.dev/sources/code4it)** · 8 min read · 0 upvotes · 0 comments

## Summary

Explains how to use the DebuggerDisplay attribute in .NET to show custom, readable representations of objects while debugging, instead of overriding ToString() or using LINQ projections. Covers basic usage, hiding quotes with the nq modifier, accessing nested fields and list elements, calling methods inside the display string, and using a dedicated private property for complex expressions. Also discusses why DebuggerDisplay avoids the side effects of overriding ToString (changes behavior app-wide) or using LINQ (adds runtime overhead).

## Questions this post answers

### How do I remove quotes around string values shown by DebuggerDisplay in C#?

Add the 'nq' (no-quotes) modifier after the field name inside the curly braces, such as {Title,nq}. This formatting specifier tells the debugger to render the string without surrounding quotes, which otherwise clutter the DebuggerDisplay output. It must be applied to each string field individually that you want to escape.

_daily.dev surfaces practical C# debugging tricks like this for developers polishing their workflow._

### Why does DebuggerDisplay not update after I rename a class field?

Because the DebuggerDisplay attribute value is a plain string, renaming a referenced field breaks the match silently and the unmatched text is just displayed literally instead of being evaluated. To avoid this, build the attribute string using concatenation with the nameof expression, e.g. "Title: {" + nameof(Title) + "}", so renames are caught at compile time.

_developers refactoring C# classes can find safer attribute patterns like this via daily.dev._

### Should I override ToString() or use DebuggerDisplay for debugging objects in C#?

Use DebuggerDisplay instead of overriding ToString() or using LINQ projections for debugging, since it has no side effects on application behavior or performance. Overriding ToString() changes output everywhere the object is printed, including Console.WriteLine, while a LINQ Select transformation runs on every object even without a debugger attached, hurting performance on large collections.
