Windows.Storage.FileProperties.StorageItemContentProperties

-description

Provides access to the content-related properties of an item (like a file or folder).

-remarks

You can get a StorageItemContentProperties object using the Properties property that is available on the following objects:

Note

Properties that are get or set using a property handler that is defined by another app (like Microsoft Word) may not be accessible. Instead, you can try to get these properties using a file query that is backed by the system index. For more information, see QueryOptions.

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

-examples

This example demonstrates how to retrieve content properties or specified properties from a file using StorageFile.Properties.

try
{
    StorageFile file = rootPage.sampleFile;
    if (file != null)
    {
        StringBuilder outputText = new StringBuilder();

        // Get image properties
        ImageProperties imageProperties = await file.Properties.GetImagePropertiesAsync();
        outputText.AppendLine("Date taken: " + imageProperties.DateTaken);
        outputText.AppendLine("Rating: " + imageProperties.Rating);

        // Specify more properties to retrieve
        readonly string dateAccessedProperty = "System.DateAccessed";
        readonly string fileOwnerProperty = "System.FileOwner";
        List<string> propertiesName = new List<string>();
        propertiesName.Add(dateAccessedProperty);
        propertiesName.Add(fileOwnerProperty);

        // Get the specified properties through StorageFile.Properties
        IDictionary<string, object> extraProperties = await file.Properties.RetrievePropertiesAsync(propertiesName);
        var propValue = extraProperties[dateAccessedProperty];
        if (propValue != null)
        {
            outputText.AppendLine("Date accessed: " + propValue);
        }
        propValue = extraProperties[fileOwnerProperty];
        if (propValue != null)
        {
            outputText.AppendLine("File owner: " + propValue);
        }
    }
}
// Handle errors with catch blocks
catch (FileNotFoundException)
{
 // For example, handle a file not found error
}

After GetImagePropertiesAsync completes, imageProperties gets a ImageProperties object. Additionally, after RetrievePropertiesAsync completes, extraProperties gets an object that contains the specified properties (the list of supported properties can be found on the Core properties page).

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