Examples

Shows how to work with custom document properties.

Document doc = new Document(MyDir + "Properties.docx");

// Every document contains a collection of custom properties, which, like the built-in properties, are key-value pairs.
// The document has a fixed list of built-in properties. The user creates all of the custom properties. 
Assert.AreEqual("Value of custom document property", doc.CustomDocumentProperties["CustomProperty"].ToString());

doc.CustomDocumentProperties.Add("CustomProperty2", "Value of custom document property #2");

Console.WriteLine("Custom Properties:");
foreach (var customDocumentProperty in doc.CustomDocumentProperties)
{
    Console.WriteLine(customDocumentProperty.Name);
    Console.WriteLine($"\tType:\t{customDocumentProperty.Type}");
    Console.WriteLine($"\tValue:\t\"{customDocumentProperty.Value}\"");
}
