### Description

An instance of the LineCollection class contains all text lines in a Text Control document or part of the document represented through objects of the type [Line](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/line/llms-full.txt). An instance of this class can be obtained with the [TextControl.Lines](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/textcontrol/lines-property/llms-full.txt), [HeaderFooter.Lines](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/headerfooter/lines-property/llms-full.txt) or [TextFrame.Lines](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/textframe/lines-property/llms-full.txt) property. The LineCollection class implements the IEnumerable and the ICollection interfaces.

### Syntax

```csharp
public class LineCollection : ICollection, IEnumerable
```

```vbnet
Public Class LineCollection
    Implements ICollection, IEnumerable
```

### Examples

The following example shows how to loop through all lines and how to get the according page number of that line.

```csharp
foreach (TXTextControl.Line line in textControl1.Lines)
{
    Console.WriteLine("Line " + line.Number.ToString() +
                     " is on page " + line.Page.ToString());
}
```

```vbnet
For Each line As TXTextControl.Line In TextControl1.Lines
    Console.WriteLine("Line " + line.Number.ToString() + _
                          " is on page " + line.Page.ToString())
Next
```

The following example works with lines in the current document.

```csharp
LineCollection lineCollection = textControl.Lines;
textControl.Text = "Quarterly results\nRevenue increased by 12%.";
```

```vbnet
Dim lineCollection As LineCollection = textControl.Lines
textControl.Text = "Quarterly results" & vbCrLf & "Revenue increased by 12%."
```
