C#中操作IIS 7.0

iDotNetSpace發表於2009-04-03
C#
 Microsoft自Windows Vista一起釋出了IIS 7.0，這個已經是去年的話題了，隨後，由.NET開發的Web程式便逐步從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，包括完全模組化的元件、文字檔案的配置功能、MMC圖形模式管理工具等等，並且與.NET程式語言結合得更加緊密了，在新新增的Microsoft.Web.Administration名稱空間中也增加了很多用於管理和訪問IIS的物件，從而使得通過程式設計方式操作IIS更加簡便。雖然在IIS 6.0時代我們也可以非常輕鬆地通過C#來管理伺服器的IIS，但相對來說，現在需要編寫的程式碼更少，所能完成的功能更強。以下是我在曾經做的一個專案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，包括建立和刪除站點、建立和刪除虛擬目錄、建立和刪除應用程式池、新增站點預設文件、判斷站點和虛擬目錄是否存在、以及檢查Bindings資訊等。

    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，趕緊貼程式碼吧。

    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呼叫介面，包括了建立站點時應用程式池的建立和許可權的管理。

            if (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。

            mgr.CommitChanges();
        }
    }
}

    然後是對虛擬目錄的操作，包括建立和刪除虛擬目錄，都比較簡單。

     以上程式碼均在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。
