Properties

Name Description
Count { get; } Gets the number of elements contained in the collection.
Item { get; set; } Gets or sets an item at the specified index.

Methods

Name Description
Add(CustomPart) Adds an item to the collection.
Clear() Removes all elements from the collection.
Clone() Makes a deep copy of this collection and its items.
GetEnumerator() Returns an enumerator object that can be used to iterate over all items in the collection.
RemoveAt(int) Removes an item at the specified index.

Remarks

You do not normally need to create instances of this class. You access custom parts related to the OOXML package via the PackageCustomParts property.

Examples

Shows how to access a document’s arbitrary custom parts collection.

Document doc = new Document(MyDir + "Custom parts OOXML package.docx");

Assert.AreEqual(2, doc.PackageCustomParts.Count);

// Clone the second part, then add the clone to the collection.
CustomPart clonedPart = doc.PackageCustomParts[1].Clone();
doc.PackageCustomParts.Add(clonedPart);
Assert.AreEqual(3, doc.PackageCustomParts.Count);

// Enumerate over the collection and print every part.
using (IEnumerator<CustomPart> enumerator = doc.PackageCustomParts.GetEnumerator())
{
    int index = 0;
    while (enumerator.MoveNext())
    {
        Console.WriteLine($"Part index {index}:");
        Console.WriteLine($"\tName:\t\t\t\t{enumerator.Current.Name}");
        Console.WriteLine($"\tContent type:\t\t{enumerator.Current.ContentType}");
        Console.WriteLine($"\tRelationship type:\t{enumerator.Current.RelationshipType}");
        Console.WriteLine(enumerator.Current.IsExternal ?
            "\tSourced from outside the document" :
            $"\tStored within the document, length: {enumerator.Current.Data.Length} bytes");
        index++;
    }
}

// We can remove elements from this collection individually, or all at once.
doc.PackageCustomParts.RemoveAt(2);

Assert.AreEqual(2, doc.PackageCustomParts.Count);

doc.PackageCustomParts.Clear();

Assert.AreEqual(0, doc.PackageCustomParts.Count);
