Examples

This example demonstrates how to use a file query that is backed by the system index to retrieve document properties like Title.

try
{
    // Create index backed file query and get results
    List<string> fileTypeFilter = new List<string>();
    fileTypeFilter.Add(".docx");
    QueryOptions queryOptions = new QueryOptions(Windows.Storage.Search.CommonFileQuery.OrderByName, fileTypeFilter);
    queryOptions.IndexerOption = IndexerOption.OnlyUseIndexer;
    StorageFileQueryResult queryResult = Windows.Storage.KnownFolders.DocumentsLibrary.CreateFileQueryWithOptions(queryOptions);
    var files = await queryResult.GetFilesAsync();

    // Process resulting files
    if (files.Count == 0)
    {
        // Perform tasks to handle no files found
    }
    else
    {
        // Access properties for each file
        foreach (StorageFile file in files)
        {
            var documentProperties = await file.Properties.GetDocumentPropertiesAsync();
            // Perform tasks with document properties
            String title = documentProperties.Title;
        }
    }
}
// Handle errors with catch blocks
catch (FileNotFoundException)
{
 // For example, handle a file not found error
}

While the example uses the DocumentsLibrary to create the query, you can create a query like this for any folder you have access to that you can get as a StorageFolder.

In the example, file contains a StorageFile that represents the file to retrieve properties for.

Remarks

You can access a DocumentProperties object asynchronously using the GetDocumentPropertiesAsync method from the Properties property of an item (like a file of folder), or synchronously using the DocumentProperties property if it is available. You can get a DocumentProperties object using any of the following methods and properties:

• FileInformation.documentProperties property
• FolderInformation.documentProperties property
• StorageItemContentProperties.getDocumentPropertiesAsync method, which can be accessed using the Properties property, if it is available.

For more code samples about accessing properties, see the File access sample.
