繼承

欄位

Lower 2

將所有的字元轉換成小寫。

Normal 0

字元的大小寫不會變更。

Upper 1

範例

下列範例會 TextBox 建立用來接受密碼的控制項。 這個範例會 CharacterCasing 使用 屬性來變更所有輸入為大寫的字元,以及 MaxLength 將密碼長度限制為八個字元的屬性。 此範例也會使用 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
