.NET的类型层次查看工具，ClassHierarchyViewer，0.3.0.1

上周为了快速了解一个.NET的库而需要查看其类型层次。假如要在文章中表示一个类型层次，还是用文本比较舒服，截图始终是不方便。Reflector虽然能够显示类型层次，但我无法方便的把显示出来的类型层次转换为文本形式。而且，Reflector在显示基类和派生类的时候都会使用类型的全名，但有时候我只需要看到类型的简单名字。我也找过另外几个工具，例如.NET Framework SDK以前自带的Windows 窗体类查看器(Wincv.exe)，但它只显示类型自身的信息以及基类的信息，而不显示派生类的信息，还是不够用。

没找到现成合用的工具，只好自己写一个了。于是就用C#/WinForms写了一个简单的GUI程序，只是用来显示类型层次信息，并且能把类型层次以文本形式复制到剪贴板。

截图一张：

对应这张截图得到的文本表示：
IList<T>
  Collection<T>
  KeyedCollection<TKey, TItem>
  List<T>
  ReadOnlyCollection<T>

开源形式：

该程序采用MIT形式的许可证开放源代码。程序与源码可在下面链接的压缩包中获得。

运行环境：

由于使用了LINQ，这个程序需要.NET Framework 3.5才能正常运行。如果需要移植到.NET Framework 2.0的话，可以使用Mono的System.Core.dll的实现。

使用方法：

可以从命令行提供参数来打开assembly，格式为：
ClassHierarchyViewer <assembly-path>
或者直接启动程序，并通过以下三种方式的任意一种来打开assembly：
1、在文本框中输入assembly的完整名称（Name,Version,Culture,PublicKeyToken），并按回车或点击“Load By Name”按钮；
2、按“Open File...”按钮通过对话框选取assembly；
3、从文件浏览器把assembly拖放到该程序的窗口里。

同一时间只会有一个assembly显示在窗口中。

其它功能应该不言而喻了，我就直接把readme文件的内容帖出来吧：

Name: ClassHierarchyViewer
Author: RednaxelaFX (Kris Mok, rednaxela0607@hotmail.com)
Version: 0.3.0.1
Release Date: 2008-09-23

License: MIT style license. See License.txt.

////////////////////////////////////////////////////////////////

Description:

A simple tool that shows the class hierarchy within a given
.NET assembly.

Required Environment:
Windows XP or Vista, with .NET Framework 3.5 or above installed.

////////////////////////////////////////////////////////////////

Usage:

1. Start program from command line:
usage: ClassHierarchyViewer <assembly-path>

- or -

2. Start program from GUI:
Assemblies can be loaded by one of:
  * enter the assembly's full name in the combobox, then click
      "Load By Name" button;
  * enter the assembly's full name in the combobox, and hit
      Enter;
  * Click "Open File..." button, and choose an assembly file;
  * Drag and drop a assembly file from Explorer.

Only one assembly is active at a time.

A few commonly used BCL assemblies' names are added to the
combox already, including:

Functions:

The GUI window is divided into 3 major components:

1. Class List Window (on the left)

Displays all types (except "<Module>") in the given assembly,
grouped by their namespaces, sorted by the type's name.
Types that are not visible outside the assembly are marked gray.

2. Class Hierarchy Window (on the upper right)

When a type is selected in the Class List Window, its type
hierarchy will be shown in this window.
The hierarchy shown includes the type itself, its base type (up
to System.Object), and all its derived types.

Checking/unchecking the "Full Name" checkbox will cause this
window to reload, showing types with their simple name/full name.

Clicking "Copy to Clipboard" button will copy the type hierarchy
to the clipboard, in text representaion.

3. Class Member Window (on the lower right)

When a type is selected in the Class Hierarchy Window, its
members will be shown in this window. This does not include
a type's nested types.

Checking/unchecking the "Use Alias" checkbox will cause this
window to reload, showing types with their alias/name.

////////////////////////////////////////////////////////////////

Known Issues:

1. TreeViews flicker when mouse moves over them rapidly.
  Haven't found any solution to this, maybe that's just how
  WinForms behaves.

2. Copying the type hierarchy causes flickering.
  This is because of the way data is loaded: derived types are
  added onto the tree when a node is expanded. To make sure
  derived types are added correctly, the whole tree is expanded
  before its text representation can be gathered. This will be
  improved in later versions with M-V-VM pattern.

3. Properties' getter and setter methods aren't associated with
the properties' nodes.
  Due to the lack of developing time, certain useful functions
  such as this one is not implemented yet. Will be fixed in
  later versions.

4. Doesn't show what interfaces a type implements.
  Same as above. Will be fixed.

5. Cannot load an assembly from GAC just by browsing in the open
file dialog.
  I know. That's why there's an alternative, to load assemblies
  with their full names. Later on I might add a dialog to select
  assemblies from GAC.

现在这个简陋的程序最大的限制就是无法自如的打开GAC里的assembly，因为在Windows上安装.NET Framework之后，GAC目录默认会被Fusion管理起来，需要通过修改注册表来禁用这个功能才能看到GAC里的assembly的路径。当然，我可以扫描%WINDOWS%\Assembly\下的所有assembly，不过这个功能还没做进来；别的类似程序在扫描GAC时非常慢，所以我不太肯定要不要把这个功能做进来。现在通过强名称一样能打开GAC里的assembly，只是用户会辛苦一点了。预先放在文本框的下拉列表里的名称应该能满足一般使用需要了吧。
