在 C# 中进行 Windows 突出显示搜索

发布于 2024-07-19 02:51:22 字数 99 浏览 5 评论 0原文

是否可以通过c# 来实际进行Windows 搜索（您在Vista 中从带有突出显示的菜单中找到的搜索（例如您写“fire”并得到“firefox”））。

谢谢：）

是的，这可以通过 Windows 桌面搜索 (WDS) API 实现。您需要 SDK ，如果我没记错的话，它甚至提供了一个 .Net 程序集。然后查看文档了解如何查询WDS索引。这很简单，这是他们提供的 C# 示例：

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();

当我不久前在项目中使用它时，我使用的查询字符串是这样构建的：

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

然后进行简单的文件搜索：

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

从文档中您可以看到如何构建查询为您带来所需的结果。

现在，快速说明一下。我能够构建 Vista 开始搜索克隆，但是，我首先扫描 Vista 存储开始菜单链接的位置中的链接文件 (%appdata%\Microsoft\Windows\Start Menu & C:\ProgramData\Microsoft\ Windows\开始菜单），然后在后台异步加载 WDS 结果，这比仅依赖 WDS 更好地复制开始搜索行为。

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();

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;

Then to do a simple file search:

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

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

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.
