如何在 C# 中查找 IIS 站点 ID？

How can I look up IIS site id in C#?

提问by Grzenio

I am writing an installer class for my web service. In many cases when I use WMI (e.g. when creating virtual directories) I have to know the siteId to provide the correct metabasePath to the site, e.g.:

我正在为我的 Web 服务编写一个安装程序类。在许多情况下，当我使用 WMI 时（例如在创建虚拟目录时），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" 

How can I look it up programmatically in C#, based on the name of the site (e.g. for "Default Web Site")?

如何根据站点名称（例如“默认网站”）在 C# 中以编程方式查找它？

Here is how to get it by name. You can modify as needed.

这是按名称获取它的方法。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;
}

Maybe not the best way, but here is a way :

也许不是最好的方法，但这里有一个方法：

1. loop through all the sites under "IIS://servername/service"
2. for each of the sites check if the name is "Default Web Site" in your case
3. if true then you have your site id

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“默认网站”
3. 如果为真，那么你有你的网站 ID

Example :

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

You can search for a site by inspecting the ServerCommentproperty belonging to children of the metabase path IIS://Localhost/W3SVCthat have a SchemaClassNameof IIsWebServer.

您可以通过检查搜索的网站ServerComment属于数据库路径的子女财产IIS://Localhost/W3SVC有一个SchemaClassName的IIsWebServer。

The following code demonstrates two approaches:

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);
        }
    }
}

This assumes that the ServerCommentproperty has been used (IIS MMC forces its used) and is unique.

这假定该ServerComment属性已被使用（IIS MMC 强制其使用）并且是唯一的。
