FieldMapDatas

Odso.FieldMapDatas property

Gets or sets a collection of objects that specify how columns from the external data source are mapped to the predefined merge field names in the document. This object is never null.

public OdsoFieldMapDataCollection FieldMapDatas { get; set; }

Examples

Shows how to access the collection of data that maps data source columns to merge fields.

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

// This collection defines how a mail merge will map columns from a data source
// to predefined MERGEFIELD, ADDRESSBLOCK and GREETINGLINE fields.
OdsoFieldMapDataCollection dataCollection = doc.MailMergeSettings.Odso.FieldMapDatas;
Assert.AreEqual(30, dataCollection.Count);

using (IEnumerator<OdsoFieldMapData> enumerator = dataCollection.GetEnumerator())
{
    int index = 0;
    while (enumerator.MoveNext())
    {
        Console.WriteLine($"Field map data index {index++}, type \"{enumerator.Current.Type}\":");

        Console.WriteLine(
            enumerator.Current.Type != OdsoFieldMappingType.Null
                ? $"\tColumn \"{enumerator.Current.Name}\", number {enumerator.Current.Column} mapped to merge field \"{enumerator.Current.MappedName}\"."
                : "\tNo valid column to field mapping data present.");
    }
}

// Clone the elements in this collection.
Assert.AreNotEqual(dataCollection[0], dataCollection[0].Clone());

// Use the "RemoveAt" method elements individually by index.
dataCollection.RemoveAt(0);

Assert.AreEqual(29, dataCollection.Count);

// Use the "Clear" method to clear the entire collection at once.
dataCollection.Clear();

Assert.AreEqual(0, dataCollection.Count);
