如何在 C# 中查找 IIS 站点 ID？

Question

我正在为我的 web 服务编写安装程序 class。 在许多情况下，当我使用 WMI（例如创建虚拟目录时）时，我必须知道 siteId 才能为站点提供正确的元数据库路径，例如：

metabasePath is of the form "IIS://<servername>/<service>/<siteID>/Root[/<vdir>]"
for example "IIS://localhost/W3SVC/1/Root" 

如何根据站点名称（例如“默认 Web 站点”）以编程方式在 C# 中查找它？

Answer 1

以下是如何通过名称获取它。 您可以根据需要进行修改。

public int GetWebSiteId(string serverName, string websiteName)
{
  int result = -1;

  DirectoryEntry w3svc = new DirectoryEntry(
                      string.Format("IIS://{0}/w3svc", serverName));

  foreach (DirectoryEntry site in w3svc.Children)
  {
    if (site.Properties["ServerComment"] != null)
    {
      if (site.Properties["ServerComment"].Value != null)
      {
        if (string.Compare(site.Properties["ServerComment"].Value.ToString(), 
                             websiteName, false) == 0)
        {
            result = int.Parse(site.Name);
            break;
        }
      }
    }
  }

  return result;
}

您可以通过检查属于具有IIsWebServer的SchemaClassName的元数据库路径IIS://Localhost/W3SVC的子级的ServerComment属性来搜索站点。

以下代码演示了两种方法：

string siteToFind = "Default Web Site";

// The Linq way
using (DirectoryEntry w3svc1 = new DirectoryEntry("IIS://Localhost/W3SVC"))
{
    IEnumerable<DirectoryEntry> children = 
          w3svc1.Children.Cast<DirectoryEntry>();

    var sites = 
        (from de in children
         where
          de.SchemaClassName == "IIsWebServer" &&
          de.Properties["ServerComment"].Value.ToString() == siteToFind
         select de).ToList();
    if(sites.Count() > 0)
    {
        // Found matches...assuming ServerComment is unique:
        Console.WriteLine(sites[0].Name);
    }
}

// The old way
using (DirectoryEntry w3svc2 = new DirectoryEntry("IIS://Localhost/W3SVC"))
{

    foreach (DirectoryEntry de in w3svc2.Children)
    {
        if (de.SchemaClassName == "IIsWebServer" && 
            de.Properties["ServerComment"].Value.ToString() == siteToFind)
        {
            // Found match
            Console.WriteLine(de.Name);
        }
    }
}

这假定ServerComment属性已被使用（IIS MMC 强制使用它）并且是唯一的。

Answer 3

public static ManagementObject GetWebServerSettingsByServerComment(string serverComment)
        {
            ManagementObject returnValue = null;

            ManagementScope iisScope = new ManagementScope(@"\\localhost\root\MicrosoftIISv2", new ConnectionOptions());
            iisScope.Connect();
            if (iisScope.IsConnected)
            {
                ObjectQuery settingQuery = new ObjectQuery(String.Format(
                    "Select * from IIsWebServerSetting where ServerComment = '{0}'", serverComment));

                ManagementObjectSearcher searcher = new ManagementObjectSearcher(iisScope, settingQuery);
                ManagementObjectCollection results = searcher.Get();

                if (results.Count > 0)
                {
                    foreach (ManagementObject manObj in results)
                    {
                        returnValue = manObj;

                        if (returnValue != null)
                        {
                            break;
                        }
                    }
                }
            }

            return returnValue;
        }

也许不是最好的方法，但这里有一种方法：

1. 遍历“IIS://servername/service”下的所有站点
2. 对于每个站点，在您的情况下检查名称是否为“默认 Web 站点”
3. 如果为真，那么您有您的站点 ID

例子：

Dim oSite As IADsContainer
Dim oService As IADsContainer
Set oService = GetObject("IIS://localhost/W3SVC")
For Each oSite In oService
    If IsNumeric(oSite.Name) Then
        If oSite.ServerComment = "Default Web Site" Then
            Debug.Print "Your id = " & oSite.Name
        End If
    End If
Next

Answer 5

private static string FindWebSiteByName(string serverName, string webSiteName)
{
    DirectoryEntry w3svc = new DirectoryEntry("IIS://" + serverName + "/W3SVC");
    foreach (DirectoryEntry site in w3svc.Children)
    {
        if (site.SchemaClassName == "IIsWebServer"
            && site.Properties["ServerComment"] != null
            && site.Properties["ServerComment"].Value != null
            && string.Equals(webSiteName, site.Properties["ServerComment"].Value.ToString(), StringComparison.OrdinalIgnoreCase))
        {
            return site.Name;
        }
    }

    return null;
}
