示例

下面的代码示例ApplicationId显示属性，方法是从ApplicationSecurityInfo使用 ActivationContext 为当前正在执行的基于清单的应用程序创建的 实例中获取 ApplicationId 。

        {
            Console.WriteLine("Full name = " +
                AppDomain.CurrentDomain.ActivationContext.Identity.FullName);
            Console.WriteLine("Code base = " +
                AppDomain.CurrentDomain.ActivationContext.Identity.CodeBase);
            ApplicationSecurityInfo asi = new ApplicationSecurityInfo(AppDomain.CurrentDomain.ActivationContext);

            Console.WriteLine("ApplicationId.Name property = " + asi.ApplicationId.Name);
            if (asi.ApplicationId.Culture != null)
                Console.WriteLine("ApplicationId.Culture property = " + asi.ApplicationId.Culture.ToString());

            Console.WriteLine("ApplicationId.Version property = " + asi.ApplicationId.Version);
            // To display the value of the public key, enumerate the Byte array for the property.
            Console.Write("ApplicationId.PublicKeyToken property = ");
            byte[] pk = asi.ApplicationId.PublicKeyToken;
            for (int i = 0; i < pk.GetLength(0); i++)
                Console.Write("{0:x}", pk[i]);

注解

应用程序标识由发布者的公钥、应用程序名称、目标处理器体系结构、应用程序区域性和应用程序版本组成。 应用程序标识属性值对应于应用程序清单中包含的信息。 有关应用程序清单的详细信息，请参阅 ClickOnce 应用程序清单。

ApplicationId 由 ApplicationSecurityInfo 类用来标识基于清单的应用程序。

构造函数

ApplicationId(Byte[], String, Version, String, String)

初始化 ApplicationId 类的新实例。

属性

Culture	获取表示此应用程序的区域性信息的字符串。
Name	获取应用程序的名称。
ProcessorArchitecture	获取应用程序的目标处理器体系结构。
PublicKeyToken	获取应用程序的公钥标记。
Version	获取应用程序的版本。

方法

Copy()	创建并返回当前应用程序标识的相同副本。
Equals(Object)	确定指定的 ApplicationId 对象是否等效于当前 ApplicationId。
GetHashCode()	获取当前应用程序标识的哈希代码。
GetType()	获取当前实例的 Type。 (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ToString()	创建并返回应用程序标识的字符串表示。
