使用SMO重新启动SQL Server实例

Question

我的C#应用​​程序使用SMO对用户选择的SQL Server实例进行各种操作.特别是,它改变了认证模式:

ServerConnection conn = new ServerConnection(connection);
Server server = new Server(conn);

server.Settings.LoginMode = ServerLoginMode.Mixed;

更改登录后,应重新启动更多实例.但是,我在SMO中找不到任何方式来重启所选实例.

我试图谷歌这个,但只发现了一堆枚举正在运行的服务并将其名称与SQL服务器服务名称进行比较的示例.我不喜欢这种方式,因为它容易出错并且依赖于Microsoft当前命名SQL服务器实例的方式.

有没有办法在SMO中重新启动所选实例？

添加对 的引用System.ServiceProcess。

using System.ServiceProcess;

public static void RestartService(string sqlInstanceName) {
    if (string.IsNullOrEmpty(sqlInstanceName)) {
        throw new ArgumentNullException("sqlInstanceName");
    }

    const string DefaultInstanceName = "MSSQLSERVER";
    const string ServicePrefix = "MSSQL$";
    const string InstanceNameSeparator = "\\";

    string serviceName = string.Empty;
    string server = sqlInstanceName;
    string instance = DefaultInstanceName;

    if (server.Contains(InstanceNameSeparator)) {
       int pos = server.IndexOf(InstanceNameSeparator);
       server = server.Substring(0, pos);
       instance = sqlInstanceName.Substring(pos + 1);
    }

    serviceName = ServicePrefix + instance;
    ServiceController sc = new ServiceController(serviceName, server);
    sc.Stop();
    sc.WaitForStatus(ServiceControllerStatus.Stopped, TimeSpan.FromSeconds(30));
    sc.Start();
    sc.WaitForStatus(ServiceControllerStatus.Running, TimeSpan.FromSeconds(30));
}
