IIS安装

栏目介绍如何使用IIS API禁用IP访问

免费推荐：IIS安装

这个类是基于 Microsoft.Web.Administration 写的一个简单封装：
PS: Microsoft.Web.Administration 可通过 Nuget 搜索安装。

public class IISAdministration{    private readonly ServerManager serverManager;    public IISAdministration()    {        serverManager = new ServerManager();    }    public IEnumerable<WorkerProcess> GetWorkerProcesses()    {        return serverManager.WorkerProcesses;    }    public IEnumerable<string> GetSiteNames()    {        foreach (var item in GetWorkerProcesses())        {            yield return item.AppPoolName;        }    }    public ConfigurationElementCollection GetIpSecurityCollection(string site)    {        return GetConfigurationElementCollection("system.webServer/security/ipSecurity", site);    }    public ConfigurationElementCollection GetConfigurationElementCollection(string sectionName, string site = "")    {        var config = serverManager.GetApplicationHostConfiguration();        ConfigurationSection section;        if (string.IsNullOrWhiteSpace(site))        {            section = config.GetSection(sectionName);        }        else        {            section = config.GetSection(sectionName, site);        }        return section.GetCollection();    }    public void CreateElement(ConfigurationElementCollection section, ConfigurationElement element)    {        section.Add(element);        serverManager.CommitChanges();    }    public void RemoveElement(ConfigurationElementCollection section, ConfigurationElement element)    {        section.Remove(element);        serverManager.CommitChanges();    }    public bool HasBlocked(string siteName, string ip)    {        var ipSecurityCollection = this.GetIpSecurityCollection(siteName);        for (int i = 0; i < ipSecurityCollection.Count; i++)        {            var element = ipSecurityCollection[i];            if ((string)element["ipAddress"] == ip)            {                return true;            }        }        return false;    }    public void FreeIP(string siteName, string ip)    {        if (!HasBlocked(siteName, ip))        {            return;        }        var ipSecurityCollection = this.GetIpSecurityCollection(siteName);        for (int i = 0; i < ipSecurityCollection.Count; i++)        {            var element = ipSecurityCollection[i];            if ((string)element["ipAddress"] == ip)            {                this.RemoveElement(ipSecurityCollection, element);                break;            }        }    }    public void BlockIP(string siteName, string ip)    {        if (HasBlocked(siteName, ip))        {            return;        }        var ipSecurityCollection = this.GetIpSecurityCollection(siteName);        var element = ipSecurityCollection.CreateElement("add");        element["ipAddress"] = ip;        element["allowed"] = false;        ipSecurityCollection.Add(element);        serverManager.CommitChanges();    }}

使用方法：

var iisAdministration = new IISAdministration();iisAdministration.BlockIP("", "192.0.0.1");
