TextBoxBase.WordWrap 属性
指示多行文本框控件在必要时是否自动换行到下一行的开始。
**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）
语法
声明
<LocalizableAttribute(True)> _
Public Property WordWrap As Boolean
用法
Dim instance As TextBoxBase
Dim value As Boolean
value = instance.WordWrap
instance.WordWrap = value
[LocalizableAttribute(true)]
public bool WordWrap { get; set; }
[LocalizableAttribute(true)]
public:
property bool WordWrap {
bool get ();
void set (bool value);
}
/** @property */
public boolean get_WordWrap ()
/** @property */
public void set_WordWrap (boolean value)
public function get WordWrap () : boolean
public function set WordWrap (value : boolean)
属性值
如果多行文本框控件可换行，则为 true；如果当用户键入的内容超过了控件的右边缘时，文本框控件自动水平滚动，则为 false。默认为 true。
备注
如果此属性设置为 true，则不管 ScrollBars 属性的设置是什么，都不会显示水平滚动条。
示例
下面的代码示例使用派生类 TextBox 来创建一个带垂直滚动条的多行 TextBox 控件。此示例还使用 AcceptsTab、AcceptsReturn 和 WordWrap 属性来使多行文本框控件可用于创建文本文档。
Public Sub CreateMyMultilineTextBox()
' Create an instance of a TextBox control.
Dim textBox1 As New TextBox()
' Set the Multiline property to true.
textBox1.Multiline = True
' Add vertical scroll bars to the TextBox control.
textBox1.ScrollBars = ScrollBars.Vertical
' Allow the RETURN key in the TextBox control.
textBox1.AcceptsReturn = True
' Allow the TAB key to be entered in the TextBox control.
textBox1.AcceptsTab = True
' Set WordWrap to true to allow text to wrap to the next line.
textBox1.WordWrap = True
' Set the default text of the control.
textBox1.Text = "Welcome!" & Environment.NewLine & "Second Line"
End Sub
public void CreateMyMultilineTextBox()
{
// Create an instance of a TextBox control.
TextBox textBox1 = new TextBox();
// Set the Multiline property to true.
textBox1.Multiline = true;
// Add vertical scroll bars to the TextBox control.
textBox1.ScrollBars = ScrollBars.Vertical;
// Allow the RETURN key in the TextBox control.
textBox1.AcceptsReturn = true;
// Allow the TAB key to be entered in the TextBox control.
textBox1.AcceptsTab = true;
// Set WordWrap to true to allow text to wrap to the next line.
textBox1.WordWrap = true;
// Set the default text of the control.
textBox1.Text = "Welcome!" + Environment.NewLine + "Second Line";
}
public:
void CreateMyMultilineTextBox()
{
// Create an instance of a TextBox control.
TextBox^ textBox1 = gcnew TextBox;
// Set the Multiline property to true.
textBox1->Multiline = true;
// Add vertical scroll bars to the TextBox control.
textBox1->ScrollBars = ScrollBars::Vertical;
// Allow the RETURN key in the TextBox control.
textBox1->AcceptsReturn = true;
// Allow the TAB key to be entered in the TextBox control.
textBox1->AcceptsTab = true;
// Set WordWrap to true to allow text to wrap to the next line.
textBox1->WordWrap = true;
// Set the default text of the control.
textBox1->Text = "Welcome!" + Environment::NewLine + "Second Line";
}
public void CreateMyMultilineTextBox()
{
// Create an instance of a TextBox control.
TextBox textBox1 = new TextBox();
// Set the Multiline property to true.
textBox1.set_Multiline(true);
// Add vertical scroll bars to the TextBox control.
textBox1.set_ScrollBars(ScrollBars.Vertical);
// Allow the RETURN key in the TextBox control.
textBox1.set_AcceptsReturn(true);
// Allow the TAB key to be entered in the TextBox control.
textBox1.set_AcceptsTab(true);
// Set WordWrap to true to allow text to wrap to the next line.
textBox1.set_WordWrap(true);
// Set the default text of the control.
textBox1.set_Text("Welcome!" + Environment.get_NewLine()
+ "Second Line");
} //CreateMyMultilineTextBox
