示例

下面的示例演示如何注册 DependencyProperty，以供 DependencyObject 使用。此代码示例是 Send Email SDK 示例的一部分，来自 SendMailActivity.cs 文件。有关详细信息，请参阅发送邮件活动。

// Define the DependencyProperty objects for all of the Properties
// ...and Events exposed by this activity
public static DependencyProperty FromProperty = DependencyProperty.Register("From", typeof(string), typeof(SendEmailActivity), new PropertyMetadata("someone@example.com"));
public static DependencyProperty ToProperty = DependencyProperty.Register("To", typeof(string), typeof(SendEmailActivity), new PropertyMetadata("someone@example.com"));

' Define the DependencyProperty objects for all of the Properties 
' ...and Events exposed by me activity
Public Shared FromEmailProperty As DependencyProperty = DependencyProperty.Register("From", GetType(String), GetType(SendEmailActivity), New PropertyMetadata("someone@example.com"))
Public Shared ToProperty As DependencyProperty = DependencyProperty.Register("To", GetType(String), GetType(SendEmailActivity), New PropertyMetadata("someone@example.com"))
