Remarks
The DocumentCustomPropertyDictionary class allows you to add custom metadata (or document properties) to the presentation file. Call the Add method to add a new custom property. The following property types are available:
The following code snippet creates new custom properties:
using DevExpress.Docs.Presentation;
using (var presentation = new Presentation(File.ReadAllBytes("C:\\Documents\\Presentation.pptx")))
{
var customProperties = presentation.DocumentProperties.CustomProperties;
customProperties.Add("string property", "string");
customProperties.Add("boolean property", true);
customProperties.Add("date property", DateTime.Now);
customProperties.Add("int property", 5);
customProperties.Add("double property", 2.55);
presentation.SaveDocument(new FileStream("C:\\Documents\\Presentation_upd.pptx", FileMode.Create));
}
You can also use the Item[TKey] property to add a new custom property. Set a value to the property with the name specified in square brackets. If a property with this name does not exist, it is created automatically. Otherwise, an exception occurs.
using DevExpress.Docs.Presentation;
using (var presentation = new Presentation(File.ReadAllBytes("C:\\Documents\\Presentation.pptx"))) {
var customProperties = presentation.DocumentProperties.CustomProperties;
customProperties["string property"] ="string";
customProperties["boolean property"] = true;
customProperties["date property"] = DateTime.Now;
customProperties["int property"] = 5;
customProperties["double property"] = 2.55;
presentation.SaveDocument(new FileStream("C:\\Documents\\Presentation_upd.pptx", FileMode.Create));
}
