使在C＃中的窗口亮点搜索 [英] make a windows highlight search in c#

问题描述

有没有可能通过C＃来真正地执行Windows搜索（一个你从higlighting菜单在Vista中找到（比如你写'火'，让'火狐'））。

Would it be possible through c# to actually do a windows search (the one you find in Vista from the menu with higlighting (e.g you write 'fire' and get 'firefox')).

推荐答案

是的，这是可能与Windows桌面搜索（WDS）API。你需要的 SDK ，它甚至还提供了.NET程序集，如果我没有记错。再看看文档，了解如何查询WDS索引。这很简单，这里是他们提供的C＃示例：

Yes, this is possible with the Windows Desktop Search (WDS) API. You'll need the SDK, which even provides a .Net assembly if I recall correctly. Then look at the documentation to learn how to query the WDS index. It's quite simple, here's the C# example they provide:

OleDbConnection conn = new OleDbConnection(
    "Data Source=(local);Initial Catalog=Search.CollatorDSO;Integrated Security=SSPI;User ID=<username>;Password=<password>");

OleDbDataReader rdr = null;

conn.Open();

OleDbCommand cmd = new OleDbCommand("SELECT Top 5 System.ItemPathDisplay FROM SYSTEMINDEX", conn);

rdr = cmd.ExecuteReader();

while (rdr.Read())
{
    Console.WriteLine(rdr[0]);
}

rdr.Close();
conn.Close();

当我在一个项目中使用此一段时间回来，我使用的查询字符串建这样的事情：

When I used this in a project awhile back, the query string I used was built something like this:

CSearchManager SearchManager = new CSearchManager();
CSearchCatalogManager CatalogManager = SearchManager.GetCatalog("SystemIndex");
CSearchQueryHelper QueryHelper = CatalogManager.GetQueryHelper();
string connection_string = QueryHelper.ConnectionString;

然后做一个简单的文件搜索：

Then to do a simple file search:

QueryHelper.QueryWhereRestrictions = "AND scope='file:'";
QueryHelper.QuerySorting = "System.ItemNameDisplay ASC";
string sqlQuery = QueryHelper.GenerateSQLFromUserQuery(Filename);

从文档，你可以看到如何构建得到你需要的结果的查询。

From the documentation you can see how to build queries that get you the results you need.

现在，快速注意到。我是能够建立一个Vista的开始搜索克隆，但是，我做到了通过在Vista中的商店开始菜单链接（％APPDATA％\Microsoft\Windows\Start菜单和放大器的地方第一次扫描链接文件; C：\ ProgramData\Microsoft\Windows\Start菜单），然后异步加载WDS导致在后台，它复制开始搜索行为不是单纯的依靠WDS更好。

Now, a quick note. I was able to build a Vista Start Search clone, however, I did it by first scanning link files in the places where Vista stores Start Menu links (%appdata%\Microsoft\Windows\Start Menu & C:\ProgramData\Microsoft\Windows\Start Menu), then asynchronously loading WDS results in the background, which replicates Start Search behavior better than relying solely on WDS.
