+表示用于输入和处理密码的控件。
+
+``` CS
+[TemplatePart(Name = ElementPasswordBox, Type = typeof(System.Windows.Controls.PasswordBox))]
+[TemplatePart(Name = ElementTextBox, Type = typeof(System.Windows.Controls.TextBox))]
+public class PasswordBox : Control, IDataInput

+
+# 创建PasswordBox
+
+``` XML

+# 输入密码
+
+可以通过文本框输入密码，也可以在XAML钟或代码中这样设置日期。
+
+``` XML
+
+```
+
+``` CS
+passwordBox.Password = "123456";
+```
+
+# 显示密码
+
+PasswordBox控件可以主动显示已输入的密码。将`ShowEyeButton`设置为`true`，PasswordBox将显示一个“眼睛”的按钮，点击这个按钮即可显示已输入的密码。
+
+``` XML
+
+```
+
+
+
+
+# 设置标题和占位符文本
+
+你可以将 Header（标题）和 Placeholder（占位符）添加到PasswordBox，以向用户指示其用途。
+
+``` XML
+
+```
+
+``` CS
+var textBox = new TextBox();
+```
+
+# 输入文本
+
+此示例演示如何使用 Text 属性设置 TextBox 控件的初始文本内容：
+
+``` XML
+
+```
+
+``` CS
+textBox.Text = "这是内容";
+```
+
+生成的TextBox如下图所示：
+
+
+
+
+有关TextBox的更多示例，可以参考它的基类的[文档](https://docs.microsoft.com/zh-cn/dotnet/api/system.windows.controls.textbox?view=netframework-4.8)。
+
+
+# 设置标题和占位符文本
+
+你可以将 Header（标题）和 Placeholder（占位符）添加到TextBox，以向用户指示其用途。要使用这两个属性，
+
+``` XML
+ e) => RaiseEvent(e);
+ protected virtual void OnValueChanged(FunctionEventArgs e)
+ {
+ RaiseEvent(e);
+ UpdateItems();
