Features

Explorer tree

• Organized as Assembly → Namespace → Type → Members.
• Type nodes expand into grouped members (Constructors/Methods/Properties/Fields/Events/Enums).

Details panel (Summary + Raw)

• Selecting any node updates the details panel.
• Summary shows structured fields (assembly/namespace/type/member metadata).
• Raw shows the original dump text from the selection.
• Copy helpers: RVA, Offset, VA, Snippet.
• Export selection to JSON / CSV (type or member).

Search (fast + scoped)

• Bottom-right results panel with:
  • Query box with debounced, non-blocking filtering
  • Kind filters (Namespace/Type/Members)
  • Optional scope (All / Selected Assembly / Selected Namespace / Selected Type)
• Results highlight matched substrings.
• Click a result to navigate to the tree item.

Snippets (Generate BNM/Frida-style hooks, or Customize it)

• Right-click members and Generate Snippet.
• Template system with placeholders (e.g. ${assemblyName}, ${namespace}, ${className}, ${methodName}, ${parameterCount}).
• Manage multiple templates, pick a default, and preview output.

Favorites

• Right-click a type/member and Add to Favorites.
• Favorites panel lets you jump back to frequently used targets.

Compare / Diff (two dumps)

• Detects changes in Signatures, Offset, RVA, and VA.
• Grouped results tree: Assembly → Type → Entries.
• Filter by status + text search.
• Export visible diffs to JSON / CSV.

Building

Requirements

• CMake 3.20+
• A C++20 compiler
• Qt6 (Widgets + Concurrent)

Configure + build (CMake)

cmake -S . -B build
cmake --build build --config Release

• Then run (change path):

PATH\TO\QT\mingw_64\bin\windeployqt.exe --release --no-translations --no-system-d3d-compiler DumpCsExplorer.exe

Run

Open the built executable, then:

• Click Open dump.cs
• Optionally click Compare... after the first dump loads

Project layout

• src/parser/
  • DumpCsParser.*: parsing logic for dump.cs into a lightweight in-memory model
• src/ui/
  • MainWindow.*: main UI, tree population, searching, diff dialog

Notes

• This tool does not generate dumps. It assumes you already have dump.cs.
• Intended for large files: lazy-loading + lightweight indexing to keep interactions snappy.

Settings / config

Settings (templates, UI state, recent files, favorites) are stored via QSettings in the per-user app config location:

AppData/Local/DumpCsExplorer/DumpCsExplorer.ini
