### Description

An instance of the Line class represents a single line in a Text Control document.

### Syntax

```csharp
public class Line
```

```vbnet
Public Class Line
```

### Examples

The following example shows how to read the document line by line.

```csharp
textControl1.Text = "Line 1\nLine 2\nLine 3";

foreach (TXTextControl.Line line in textControl1.Lines)
{
    Console.WriteLine("Line #" + line.Number.ToString() + " starts at: " +
        line.Start.ToString() + ". Text: " + line.Text);
}
```

```vbnet
TextControl1.Text = "Line 1" + vbCrLf + "Line 2" + vbCrLf + "Line 3"

For Each line As TXTextControl.Line In TextControl1.Lines
    Console.WriteLine("Line #" + line.Number.ToString() + " starts at: " + _
            line.Start.ToString() + ". Text: " + line.Text)
Next
```

The following example examines the first line in a short document.

```csharp
textControl.Text = "Quarterly results\nRevenue increased by 12%.";
Line line = textControl.Lines[1];
```

```vbnet
textControl.Text = "Quarterly results" & vbCrLf & "Revenue increased by 12%."
Dim line As Line = textControl.Lines(1)
```
