类似Windows Search的文件搜索系统

Introduction

WinSearchFile is a program that I developed and I usually use it to search files on my PC.

Sometimes the search engine integrated with Explorer doesn't work fine, especially when I try to find text contained into files, so I decided to build my own search program.

There are a lot of search programs available to install on your PC but this one, without indexing your data, is simple and fast enough to help you in your search.

Inside the application

WinSearchFile layout is simple and quite similar to the Explorer integrated search. It is possible to write a pattern search (wildcards admitted) and/or a text to search into file contents (you can also decide for a case sensitive search).

In the "look in" area, you have all the disks of your computer (network connection included). To obtain this list, I use the DiskCollection class developed by dmihailescu in his Get Logical Drives Information article.

In the WinSearchFile application, I use threads to make the same search simultaneously on different targets; I use a thread for each target drive.

Threads use the FileSearch class to do their work. To update controls or data structures on main threads, use delegate functions. I defined a delegate function for the AddListBoxItem method:

To quick launch WinSearchFile, you can create a shortcut to it on your desktop and assign to this one a shortcut key.
