Lines Property

TextBoxBase.Lines Property

Gets or sets the lines of text in a text box control.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

[LocalizableAttribute(true)] 
public string[] Lines { get; set; }
/** @property */
public String[] get_Lines ()

/** @property */
public void set_Lines (String[] value)

public function get Lines () : String[]

public function set Lines (value : String[])

Property Value

An array of strings that contains the text in a text box control.

Each element in the array becomes a line of text in the text box control. If the Multiline property of the text box control is set to true and a newline character appears in the text, the text following the newline character is added to a new element in the array and displayed on a separate line.

NoteNote

By default, the collection of lines is a read-only copy of the lines in the TextBox. To get a writable collection of lines, use code similar to the following: textBox1.Lines = new string[] { "abcd" };

The following code example uses TextBox, a derived class, to extract all strings of text from a multiline text box control and displays them using the Debug.WriteLine method. This example requires that a TextBox control has been created, named textBox1, and that it has been filled with lines of text.

public void ViewMyTextBoxContents()
 {
    // Create a string array and store the contents of the Lines property.
    string[] tempArray = new string [textBox1.Lines.Length];
    tempArray = textBox1.Lines;
 
    // Loop through the array and send the contents of the array to debug window.
    for(int counter=0; counter < tempArray.Length;counter++)
    {
       System.Diagnostics.Debug.WriteLine(tempArray[counter]);
    }
 }
 

public void ViewMyTextBoxContents()
{
    // Create a string array and store the contents of the Lines property.
    String tempArray[] = new String[textBox1.get_Lines().length];
    tempArray = textBox1.get_Lines();
    // Loop through the array and send the contents of the array to
    // debug window.
    for (int counter = 0; counter <= tempArray.length; counter++) {
        System.Diagnostics.Debug.WriteLine(tempArray.get_Item(counter));
    }
} //ViewMyTextBoxContents
