FileIndexing

EventHub.FileIndexing event

在文档要被索引时发生。

public event EventHandler<FileIndexingEventArgs> FileIndexing;

例子

该示例演示了如何使用事件。

string indexFolder = @"c:\MyIndex\";
string documentsFolder = @"c:\MyDocuments\";

// 创建索引
Index index = new Index(indexFolder);

// 订阅事件
index.Events.FileIndexing += (sender, args) =>
{
    if (args.DocumentFullPath.EndsWith("Protected.pdf", StringComparison.InvariantCultureIgnoreCase))
    {
        args.AdditionalFields = new DocumentField[]
        {
            new DocumentField("Tags", "Protected")
        };
    }
    if (!args.DocumentFullPath.ToLowerInvariant().Contains("important"))
    {
        args.SkipIndexing = true;
    }
};

// 索引指定文件夹中的文档
index.Add(documentsFolder);
