Description

An instance of the DataColumnInfoCollection class contains all data columns of a data table in a data source represented through objects of the type DataColumnInfo. The DataColumnInfoCollection class implements the interface ICollection<DocumentServer.DataSources.DataColumnInfo> and therefore also IEnumerable<DocumentServer.DataSources.DataColumnInfo>. This collection class is meant to be read only. For this reason all ICollection members which would cause changes to the collection content (e. g. Add(), Clear() or Remove()) throw a NotSupportedException.

Syntax

public sealed class DataColumnInfoCollection : ICollection<DataColumnInfo>, IEnumerable<DataColumnInfo>, IEnumerable

Public NotInheritable Class DataColumnInfoCollection
    Implements ICollection(Of DataColumnInfo), IEnumerable(Of DataColumnInfo), IEnumerable

Examples

The following example includes the item value from a Data Column Info Collection object in application diagnostics. The created object is then available to the surrounding document workflow.

Console.WriteLine($"Item: {dataColumnInfoCollection[1]}");
Console.WriteLine("Data Column Info Collection is ready for use.");

Console.WriteLine($"Item: {dataColumnInfoCollection.Item(1)}")
Console.WriteLine("Data Column Info Collection is ready for use.")
