Microsoft自Windows Vista一起發布了IIS 7.0，這個已經是去年的話題了，隨後，由.NET開發的Web 程序便逐步從IIS 6.0過渡到IIS 7.0上了。IIS 7.0提供了很多比上一版本更多的新特性，包括完全模塊 化的組件、文本文件的配置功能、MMC圖形模式管理工具等等，並且與.NET編程語言結合得更加緊密了， 在新添加的Microsoft.Web.Administration名稱空間中也增加了很多用於管理和訪問IIS的對象，從而使 得通過編程方式操作IIS更加簡便。雖然在IIS 6.0時代我們也可以非常輕松地通過C#來管理服務器的IIS ，但相對來說，現在需要編寫的代碼更少，所能完成的功能更強。以下是我在曾經做的一個項目中所寫的 一個類庫中的一部分，主要實現了對IIS 7.0的操作，包括創建和刪除站點、創建和刪除虛擬目錄、創建 和刪除應用程序池、添加站點默認文檔、判斷站點和虛擬目錄是否存在、以及檢查Bindings信息等。
對於IIS 7.0的介紹讀者如果有興趣的話可以看看下面的兩篇文章，我覺得不錯！

不說廢話了，趕緊貼代碼吧。
首先是對站點的管理。我寫了一個相對較為通用的私有方法，然後在對外的方法中給出了調用接口， 包括了創建站點時應用程序池的創建和權限的管理。
CreateSite
/// <summary>
/// Create a new web site.
/// </summary>
/// <param name="siteName"></param>
/// <param name="bindingInfo">"*:<port>:<hostname>" <example>"*:80:myhost.com"</example></param>
/// <param name="physicalPath"></param>
public static void CreateSite(string siteName, string bindingInfo, string physicalPath)
{
createSite(siteName, "http", bindingInfo, physicalPath, true, siteName + "Pool", ProcessModelIdentityType.NetworkService, null, null, ManagedPipelineMode.Integrated, null);
}
private static void createSite(string siteName, string protocol, string bindingInformation, string physicalPath,
bool createAppPool, string appPoolName, ProcessModelIdentityType identityType,
string appPoolUserName, string appPoolPassword, ManagedPipelineMode appPoolPipelineMode, string managedRuntimeVersion)
{
using (ServerManager mgr = new ServerManager())
{
Site site = mgr.Sites.Add(siteName, protocol, bindingInformation, physicalPath);
// PROVISION APPPOOL IF NEEDED
if (createAppPool)
{
ApplicationPool pool = mgr.ApplicationPools.Add(appPoolName);
if (pool.ProcessModel.IdentityType != identityType)
{
pool.ProcessModel.IdentityType = identityType;
}
if (!String.IsNullOrEmpty(appPoolUserName))
{
pool.ProcessModel.UserName = appPoolUserName;
pool.ProcessModel.Password = appPoolPassword;
}
if (appPoolPipelineMode != pool.ManagedPipelineMode)
{
pool.ManagedPipelineMode = appPoolPipelineMode;
}
site.Applications["/"].ApplicationPoolName = pool.Name;
}
mgr.CommitChanges();
}
}
這個是刪除站點的方法，比較簡單。
DeleteSite /// <summary>
/// Delete an existent web site.
/// </summary>
/// <param name="siteName">Site name.</param>
public static void DeleteSite(string siteName)
{
using (ServerManager mgr = new ServerManager())
{
Site site = mgr.Sites[siteName];
if (site != null)
{
mgr.Sites.Remove(site);
mgr.CommitChanges();
}
}
}
然後是對虛擬目錄的操作，包括創建和刪除虛擬目錄，都比較簡單。
CreateVDir public static void CreateVDir(string siteName, string vDirName, string physicalPath)
{
using (ServerManager mgr = new ServerManager())
{
Site site = mgr.Sites[siteName];
if (site == null)
{
throw new ApplicationException(String.Format("Web site {0} does not exist", siteName));
}
site.Applications.Add("/" + vDirName, physicalPath);
mgr.CommitChanges();
}
}
DeleteVDir public static void DeleteVDir(string siteName, string vDirName)
{
using (ServerManager mgr = new ServerManager())
{
Site site = mgr.Sites[siteName];
if (site != null)
{
Microsoft.Web.Administration.Application app = site.Applications ["/" + vDirName];
if (app != null)
{
site.Applications.Remove(app);
mgr.CommitChanges();
}
}
}
}
刪除應用程序池。
DeletePool
/// <summary>
/// Delete an existent web site app pool.
/// </summary>
/// <param name="appPoolName">App pool name for deletion.</param>
public static void DeletePool(string appPoolName)
{
using (ServerManager mgr = new ServerManager())
{
ApplicationPool pool = mgr.ApplicationPools[appPoolName];
if (pool != null)
{
mgr.ApplicationPools.Remove(pool);
mgr.CommitChanges();
}
}
}
在站點上添加默認文檔。
AddDefaultDocument public static void AddDefaultDocument(string siteName, string defaultDocName)
{
using (ServerManager mgr = new ServerManager())
{
Configuration cfg = mgr.GetWebConfiguration(siteName);
ConfigurationSection defaultDocumentSection = cfg.GetSection ("system.webServer/defaultDocument");
ConfigurationElement filesElement = defaultDocumentSection.GetChildElement ("files");
ConfigurationElementCollection filesCollection = filesElement.GetCollection();
foreach (ConfigurationElement elt in filesCollection)
{
if (elt.Attributes["value"].Value.ToString() == defaultDocName)
{
return;
}
}
try
{
ConfigurationElement docElement = filesCollection.CreateElement ();
docElement.SetAttributeValue("value", defaultDocName);
filesCollection.Add(docElement);
}
catch (Exception) { } //this will fail if existing
mgr.CommitChanges();
}
}
檢查虛擬目錄是否存在。
VerifyVirtualPathIsExist public static bool VerifyVirtualPathIsExist(string siteName, string path)
{
using (ServerManager mgr = new ServerManager())
{
Site site = mgr.Sites[siteName];
if (site != null)
{
foreach (Microsoft.Web.Administration.Application app in site.Applications)
{
if (app.Path.ToUpper().Equals(path.ToUpper()))
{
return true;
}
}
}
}
return false;
}
檢查站點是否存在。
VerifyWebSiteIsExist public static bool VerifyWebSiteIsExist(string siteName)
{
using (ServerManager mgr = new ServerManager())
{
for (int i = 0; i < mgr.Sites.Count; i++)
{
if (mgr.Sites[i].Name.ToUpper().Equals(siteName.ToUpper()))
{
return true;
}
}
}
return false;
}
檢查Bindings信息。
VerifyWebSiteBindingsIsExist public static bool VerifyWebSiteBindingsIsExist(string bindingInfo)
{
string temp = string.Empty;
using (ServerManager mgr = new ServerManager())
{
for (int i = 0; i < mgr.Sites.Count; i++)
{
foreach (Microsoft.Web.Administration.Binding b in mgr.Sites [i].Bindings)
{
temp = b.BindingInformation;
if (temp.IndexOf('*') < 0)
{
temp = "*" + temp;
}
if (temp.Equals(bindingInfo))
{
return true;
}
}
}
}
return false;
}
以上代碼均在Windows Vista SP1和Windows Server 2008上測試通過，使用時需要在工程中引用 Microsoft.Web.Administration類庫，該類庫為IIS 7.0自帶的。
