注意使用时要有服务器管理员权限 ，可在Web.config 添加
<system.web>
<identity impersonate="true" userName="服务器用户名" password="密码" />
</system.web>
先添加两个引用：
System.EnterpriseServices及System.DirectoryServices
然后再在代码中引用：
1 using System.DirectoryServices; 2 using System.EnterpriseServices;
然后就是如何添加绑定了：
1 public static void AddHostHeader(int siteid, string ip, int port, string domain)//增加主机头（站点编号.ip.端口.域名） 2 { 3 DirectoryEntry site = new DirectoryEntry("IIS://localhost/W3SVC/" + siteid); 4 PropertyValueCollection serverBindings = site.Properties["ServerBindings"]; 5 string headerStr = string.Format("{0}:{1}:{2}", ip, port, domain); 6 log4net.LogManager.GetLogger("root").Info(serverBindings.PropertyName + serverBindings.Value.ToString()); 7 if (!serverBindings.Contains(headerStr)) 8 { 9 serverBindings.Add(headerStr); 10 } 11 site.CommitChanges(); 12 }
其中，siteid，自己到IIS中看，ip不指定的话填"*"，端口一般是80，域名是怎么多少就入多少
注意：
1、添加后，会自动重启站点；
2、如果里面某个域名，重复添加，网站在重启的过程中会起不来，那就完蛋了，这个必须要配合自己的数据库；
3、必须在web.config添加权限配置：
————————————————
<system.web>
<identity impersonate="true" userName="Administrator" password="password" />
</system.web>
4、如果在IIS7中出现： DirectoryEntry配置IIS7出现ADSI Error：未知错误(0x80005000)
“控制面板”->“程序和功能”->面板左侧“打开或关闭windows功能”->“Internet信息服务”->“Web管理工具”->“IIS 6管理兼容性”->“IIS 元数据库和IIS 6配置兼容性”。更理想的解决方式是用 WMI provider操作IIS 7 ，可参见此篇文章http://msdn.microsoft.com/en-us/library/aa347459.aspx
