TableName

IMailMergeDataSource.TableName property

Returns the name of the data source.

public string TableName { get; }

Return Value

The name of the data source. Empty string if the data source has no name.

Remarks

If you are implementing IMailMergeDataSource, return the name of the data source from this property.

Aspose.Words uses this name to match against the mail merge region name specified in the template document. The comparison between the data source name and the mail merge region name is not case sensitive.

Examples

Shows how to execute a mail merge with a data source in the form of a custom object.

public void CustomDataSource()
{
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);
    builder.InsertField(" MERGEFIELD FullName ");
    builder.InsertParagraph();
    builder.InsertField(" MERGEFIELD Address ");

    List<Customer> customers = new List<Customer>
    {
        new Customer("Thomas Hardy", "120 Hanover Sq., London"),
        new Customer("Paolo Accorti", "Via Monte Bianco 34, Torino")
    };

    // To use a custom object as a data source, it must implement the IMailMergeDataSource interface. 
    CustomerMailMergeDataSource dataSource = new CustomerMailMergeDataSource(customers);

    doc.MailMerge.Execute(dataSource);

    doc.Save(ArtifactsDir + "MailMergeCustom.CustomDataSource.docx");
