ServiceAccount 枚举

定义

命名空间:

System.ServiceProcess

程序集:

System.ServiceProcess.dll

指定服务的安全上下文，安全上下文定义其登录类型。

public enum class ServiceAccount

public enum ServiceAccount

type ServiceAccount = 

Public Enum ServiceAccount

继承

Object

ValueType

Enum

ServiceAccount

字段

LocalService	0	充当本地计算机上非特权用户的帐户，该帐户将匿名凭据提供给所有远程服务器。
LocalSystem	2	服务控制管理员使用的帐户，它具有本地计算机上的许多权限并作为网络上的计算机。
NetworkService	1	提供广泛的本地特权的帐户，该帐户将计算机的凭据提供给所有远程服务器。
User	3	由网络上特定的用户定义的帐户。 如果为 Account 成员指定 User，则会使系统在安装服务时提示输入有效的用户名和密码，除非您为 Username 实例的 Password 和 ServiceProcessInstaller 这两个属性设置值。

示例

下面的代码示例演示如何使用 ServiceAccount 枚举通过系统帐户的安全上下文安装新程序。

#using <System.dll>
#using <System.ServiceProcess.dll>
#using <System.Configuration.Install.dll>

        processInstaller = gcnew ServiceProcessInstaller;
        serviceInstaller1 = gcnew ServiceInstaller;
        serviceInstaller2 = gcnew ServiceInstaller;

        // The services run under the system account.
        processInstaller->Account = ServiceAccount::LocalSystem;

注解

初始化 a ServiceProcessInstaller 时使用ServiceAccount枚举来指定要安装的服务的安全上下文。 安全上下文指示服务在系统上拥有的权限，以及服务如何对网络执行操作 (，例如，服务是否向远程服务器提供计算机的凭据或匿名凭据) 。 枚举 ServiceAccount 提供一系列特权，以便可以精确指定任何特定服务所需的特权。

该值 LocalSystem 定义高特权帐户，但大多数服务不需要这种提升的特权级别。 枚举LocalService``NetworkService成员为安全上下文提供较低的特权级别。

备注

这些值LocalService仅在 NetworkService Windows XP 和 Windows Server 2003 系列上可用。
