TextBoxBase.WordWrap 屬性

定義

命名空間:

System.Windows.Forms

組件:

System.Windows.Forms.dll

指示多行文字方塊控制項是否會在必要時自動將文字換行到下一行的開頭。

public:
 property bool WordWrap { bool get(); void set(bool value); };

public bool WordWrap { get; set; }

member this.WordWrap : bool with get, set

Public Property WordWrap As Boolean

屬性值

Boolean

如果多行文字方塊控制項會將文字換行，則為 true；如果文字方塊控制項會在使用者輸入的文字超過控制項右邊時，自動向水平方向捲動，則為 false。 預設為 true。

範例

下列程式碼範例會使用 TextBox 衍生類別來建立具有垂直捲動條的多行 TextBox 控制項。 此範例也會使用 AcceptsTab 、 AcceptsReturn 和 WordWrap 屬性，讓多行文字方塊控制項適用于建立文字檔。

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.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 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

備註

如果此屬性設定為 true ，則不論屬性設定為何 ScrollBars ，都不會顯示水準捲軸。

注意

在衍生類別中， TextBox 控制項內的文字一律會換行，不論此屬性的屬性設定為何，除非 TextAlign 屬性設定為 HorizontalAlignment.Left 。
