C#如何在Windows中操作IIS设置FTP服务器

 什么是FTP

FTP(File Transfer Protocol)是TCP/IP网络上两台计算机传送文件的协议，使得主机间可以共享文件.可以将 Internet 信息服务 (IIS) 配置为作为 FTP 服务器来运行。 这样，其他计算机便可以连接到服务器并将文件复制到服务器或者从服务器复制文件。 例如，如果您在自己的计算机上承载网站，并且希望允许远程用户连接到您的计算机并将他们的文件复制到服务器，则可以将 IIS 配置为充当 FTP 服务器。

主要实现方式

下面主要讲解一下，在Window的IIS中创建FTP的Site。

1、创建站点

public int createFtpSite(string ftpname,string path){ 
 
            int errorCode = ErrorCode.Succeed; 
            if (ftpname == "" && path == "") 
            { 
                try 
                { 
                    ServerManager iisManager = new ServerManager(); 
                    Configuration cfg = iisManager.GetApplicationHostConfiguration(); 
                     
                    try 
                    { 
                         
                        foreach (var ftpsite in iisManager.Sites) 
                        { 
                             
                            string sitename = ftpsite.Name; 
                             
                            foreach (Binding binding in ftpsite.Bindings) 
                            { 
                                try 
                                { 
                                    string currentServerBindings = binding.GetAttributeValue("BindingInformation").ToString(); 
                                    string port = currentServerBindings.Split(":".ToArray())[1]; 
                                    if (port == "21") 
                                    { 
                                        try 
                                        { 
                                            //stop site 
                                            ftpsite.Stop(); 
                                        } 
                                        catch 
                                        { 
                                            //doing nothing 
                                        } 
                                        break; 
                                    } 
                                } 
                                catch 
                                { 
                                    //doing nothing 
                                } 
                            } 
                        } 
                        //提交更改 
                        iisManager.CommitChanges(); 
                    } 
                    catch 
                    { 
                        //do nothing 
                    } 
                     
                    if (!System.IO.Directory.Exists(System.Configuration.ConfigurationManager.AppSettings.Get("defaultftpath")))//创建站点路径 
                    { 
                        System.IO.Directory.CreateDirectory(System.Configuration.ConfigurationManager.AppSettings.Get("defaultftpath")); 
                    } 
                    Site site = iisManager.Sites.Add(System.Configuration.ConfigurationManager.AppSettings.Get("defaultftp"), "ftp", string.Format("*:{0}:", "21"), System.Configuration.ConfigurationManager.AppSettings.Get("defaultftpath")); 
                    iisManager.CommitChanges(); 
                    //设置FTP SSL权限 
                    SetFtpSSL(); 
                    //设置FTP Everyone权限 
                    IISUtil.IISCore.AddSiteUtil addsiteUtil = new AddSiteUtil(); 
                    try 
                    { 
                        string config_rootpath = System.Configuration.ConfigurationManager.AppSettings.Get("defaultftpath"); 
                        //string rootpath = path.Substring(0, path.IndexOf(ftpname) - 1) + "\\ftproot"; 
                        if (!System.IO.Directory.Exists(config_rootpath)) 
                        { 
                            System.IO.Directory.CreateDirectory(config_rootpath); 
                        } 
                        addsiteUtil.icaclsSet("Everyone", System.Configuration.ConfigurationManager.AppSettings.Get("defaultftpath")); 
                         
                        System.IO.File.SetAttributes(config_rootpath, System.IO.FileAttributes.Hidden); 
                    } 
                    catch 
                    { 
 
                    } 
                } 
                catch 
                { 
                    errorCode = ErrorCode.ftpSiteFail; 
                } 
                 
            } 
            else 
            { 
                if (!getFtpState(ftpname))//判断ftp用户是否存在 
                { 
                     
                    FtpStateInit(); 
                    try 
                    { 
                        using (ServerManager iisManager = new ServerManager()) 
                        { 
                            Site site = iisManager.Sites.FirstOrDefault(o => ((string)o["name"]).Contains(System.Configuration.ConfigurationManager.AppSettings.Get("defaultftp"))); 
                            var vird = site.Applications[0].VirtualDirectories["/" + ftpname]; 
                            if (vird == null) { site.Applications[0].VirtualDirectories.Add("/" + ftpname, path); } 
                            else { errorCode = ErrorCode.ftpExists; } 
                            iisManager.CommitChanges(); 
                            //添加FTP访问权限 
                            SetFtpAccess(ftpname); 
                        } 
                    } 
                    catch 
                    { 
                        errorCode = ErrorCode.ftpSiteFail; 
                    } 
                } 
                else 
                { 
                    errorCode = ErrorCode.ftpExists; 
                } 
 
            } 
            return errorCode; 
        } 

2、站点列表

/// 
 
        /// iis6获取所有ftp站点信息 
        ///

        public static List iGetFtpInfos() 
        {

            try 
            { 
                string ftproot = System.Configuration.ConfigurationManager.AppSettings.Get("defaultftp"); 
                string ftpname = "";//用户名 
                string ftppass = "";//密码 
                string ftppath = "";//物理路径 
                string iisversion = "";//iis版本 
                string majorversion = IISCore.IISInfoUtil.SGetIISMajorVersion(); 
                if (majorversion == "") 
                { 
                    iisversion = "未知"; 
                } 
                else

                                        { 
                                            ftppass = child.Properties["AnonymousUserPass"].Value.ToString(); 
                                             
                                            foreach (DirectoryEntry rootChild in child.Children) 
                                            { 
                                                string name = rootChild.Name.ToString();

                                                        ftppath = ""; 
                                                    } 
                                                    else 
                                                    {

                                                    } 
                                                } 
                                            } 
                                        } 
                                    } 
                                } 
                                catch 
                                { 
 
                                } 
                                 
                                if(ftpname != "") 
                                    ftpinfos.Add(ftproot + "-@-" + ftpname + "-@-" + ftppass + "-@-" + ftppath + "-@-" + iisversion);//添加到站点信息 
                            }

删除站点

public static bool DeleteQFtp(string ftpname) 
        { 
            bool flag = false; 
            try{
