範例

下列程式碼範例會 TextBox 建立用來接受密碼的 控制項。 這個範例會 CharacterCasing 使用 屬性，將所有輸入為小寫的字元變更，而 MaxLength 屬性則會將密碼長度限制為八個字元。 這個範例也會使用 TextAlign 屬性將 控制項中的密碼置中 TextBox 。

public:
   void CreateMyPasswordTextBox()
   {
      // Create an instance of the TextBox control.
      TextBox^ textBox1 = gcnew TextBox;
      // Set the maximum length of text in the control to eight.
      textBox1->MaxLength = 8;
      // Assign the asterisk to be the password character.
      textBox1->PasswordChar = '*';
      // Change all text entered to be lowercase.
      textBox1->CharacterCasing = CharacterCasing::Lower;
      // Align the text in the center of the TextBox control.
      textBox1->TextAlign = HorizontalAlignment::Center;
   }

public void CreateMyPasswordTextBox()
 {
    // Create an instance of the TextBox control.
    TextBox textBox1 = new TextBox();
    // Set the maximum length of text in the control to eight.
    textBox1.MaxLength = 8;
    // Assign the asterisk to be the password character.
    textBox1.PasswordChar = '*';
    // Change all text entered to be lowercase.
    textBox1.CharacterCasing = CharacterCasing.Lower;
    // Align the text in the center of the TextBox control.
    textBox1.TextAlign = HorizontalAlignment.Center;
 }

Public Sub CreateMyPasswordTextBox()
    ' Create an instance of the TextBox control.
    Dim textBox1 As New TextBox()
    ' Set the maximum length of text in the control to eight.
    textBox1.MaxLength = 8
    ' Assign the asterisk to be the password character.
    textBox1.PasswordChar = "*"c
    ' Change all text entered to be lowercase.
    textBox1.CharacterCasing = CharacterCasing.Lower
    ' Align the text in the center of the TextBox control.
    textBox1.TextAlign = HorizontalAlignment.Center
End Sub

備註

您可以使用這個屬性來對齊 內的 TextBox 文字，以符合表單上的文字配置。 例如，如果您的控制項全都位於表單右側，您可以將 屬性 HorizontalAlignment.Right 設定 TextAlign 為 ，而文字會與控制項右側對齊，而不是預設的左對齊方式。
