我如何合并此重复的C＃代码？

Question

本质上，我的程序正在远程处理服务器，在IIS中停止应用程序池，复制文件，最后重新启动应用程序池。我必须将相同的过程应用于六个不同的服务器。如何将其整合为最简单，最有效的代码？

现在是我的代码（基本上，它已经完成了6次相同的操作：]

using (ServerManager mgr = ServerManager.OpenRemote("RemoteServer1"))
{
    ApplicationPool appPool = mgr.ApplicationPools["TestAppPool"];
    if (appPool != null)
    {
        if (appPool.State == ObjectState.Started)
        {
            appPool.Stop();
        }
    }

    File.Copy(@"C:\Users\TestUser\Downloads\testfile.txt", @"\\RemoteServer1\Users\TestUser\Documents\testfile.txt");
    appPool.Start;
}



using (ServerManager mgr = ServerManager.OpenRemote("RemoteServer2"))
{
    ApplicationPool appPool = mgr.ApplicationPools["TestAppPool"];
    if (appPool != null)
    {
        if (appPool.State == ObjectState.Started)
        {
            appPool.Stop();
        }
    }

    File.Copy(@"C:\Users\TestUser\Downloads\testfile.txt", @"\\RemoteServer2\Users\TestUser\Documents\testfile.txt");
    appPool.Start;
}



using (ServerManager mgr = ServerManager.OpenRemote("RemoteServer3"))
{
    ApplicationPool appPool = mgr.ApplicationPools["TestAppPool"];
    if (appPool != null)
    {
        if (appPool.State == ObjectState.Started)
        {
            appPool.Stop();
        }
    }

    File.Copy(@"C:\Users\TestUser\Downloads\testfile.txt", @"\\RemoteServer3\Users\TestUser\Documents\testfile.txt");
    appPool.Start;
}



using (ServerManager mgr = ServerManager.OpenRemote("RemoteServer4"))
{
    ApplicationPool appPool = mgr.ApplicationPools["TestAppPool"];
    if (appPool != null)
    {
        if (appPool.State == ObjectState.Started)
        {
            appPool.Stop();
        }
    }

    File.Copy(@"C:\Users\TestUser\Downloads\testfile.txt", @"\\RemoteServer4\Users\TestUser\Documents\testfile.txt");
    appPool.Start;
}



using (ServerManager mgr = ServerManager.OpenRemote("RemoteServer5"))
{
    ApplicationPool appPool = mgr.ApplicationPools["TestAppPool"];
    if (appPool != null)
    {
        if (appPool.State == ObjectState.Started)
        {
            appPool.Stop();
        }
    }

    File.Copy(@"C:\Users\TestUser\Downloads\testfile.txt", @"\\RemoteServer5\Users\TestUser\Documents\testfile.txt");
    appPool.Start;
}



using (ServerManager mgr = ServerManager.OpenRemote("RemoteServer6"))
{
    ApplicationPool appPool = mgr.ApplicationPools["TestAppPool"];
    if (appPool != null)
    {
        if (appPool.State == ObjectState.Started)
        {
            appPool.Stop();
        }
    }

    File.Copy(@"C:\Users\TestUser\Downloads\testfile.txt", @"\\RemoteServer6\Users\TestUser\Documents\testfile.txt");
    appPool.Start;
}

将所有内容放入以服务器名称为参数的方法中

public void CopyFileToServer(string targetServerName)
{
    using (ServerManager mgr = ServerManager.OpenRemote(targetServerName)) 
    {
        ApplicationPool appPool = mgr.ApplicationPools["TestAppPool"];
        if (appPool != null)
        {
            if (appPool.State == ObjectState.Started)
            {
                appPool.Stop();
            }
        }

        // Depending on the Framework or Core version you might need to play
        // with the string interpolation for the second parameter
        File.Copy(@"C:\Users\TestUser\Downloads\testfile.txt", @$"\\{targetServerName}\Users\TestUser\Documents\testfile.txt");
    appPool.Start;
    }
}

将这些更改之一提取为方法，将更改替换为参数：

public void CopyToRemote(string remoteServer)
{
    using (ServerManager mgr = ServerManager.OpenRemote(remoteServer))
    {
        ApplicationPool appPool = mgr.ApplicationPools["TestAppPool"];
        if (appPool != null)
        {
            if (appPool.State == ObjectState.Started)
            {
                appPool.Stop();
            }
        }

        File.Copy(@"C:\Users\TestUser\Downloads\testfile.txt", string.Format(@"\\{0}\Users\TestUser\Documents\testfile.txt", remoteServer));
        appPool.Start;
    }
}

呼叫方式：

for (int index = 1; index <= 6; index++)
{
    CopyToRemote($"RemoteServer{index}");
}
