# DataTableInfoCollection Class

> An instance of the DataTableInfoCollection class contains all data tables in a data source represented through objects of the type DataTableInfo. The DataTableInfoCollection class implements the interface ICollection<DocumentServer.DataSources.DataTableInfo> and therefore also IEnumerable<DocumentServer.DataSources.DataTableInfo>. 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.

### Description

An instance of the DataTableInfoCollection class contains all data tables in a data source represented through objects of the type [DataTableInfo](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol-documentserver-datasources/datatableinfo/llms-full.txt). The DataTableInfoCollection class implements the interface ICollection<DocumentServer.DataSources.DataTableInfo> and therefore also IEnumerable<DocumentServer.DataSources.DataTableInfo>. 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

```csharp
public sealed class DataTableInfoCollection : ICollection<DataTableInfo>, IEnumerable<DataTableInfo>, IEnumerable
```

```vbnet
Public NotInheritable Class DataTableInfoCollection
    Implements ICollection(Of DataTableInfo), IEnumerable(Of DataTableInfo), IEnumerable
```

### Examples

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

```csharp
Console.WriteLine($"Item: {dataTableInfoCollection["CustomerName"]}");
Console.WriteLine("Data Table Info Collection is ready for use.");
```

```vbnet
Console.WriteLine($"Item: {dataTableInfoCollection.Item("CustomerName")}")
Console.WriteLine("Data Table Info Collection is ready for use.")
```
