Question

下面的代码工作正常，可以读取远程IIS 6服务器的配置数据库中的所有内容 - 除了属性的frikkin'数字ID。我在PropertyValueCollection对象中找不到它们。

var site = new DirectoryEntry("IIS://" + tbHost.Text + 
                    "/W3SVC/1", tbUsername.Text, tbPassword.Password);

Console.Write("Site {0}\n", site.Name);

foreach (PropertyValueCollection prop in site.Properties)
{
    Console.Write("    {0} (Type {1})\n", prop.PropertyName, 
                                               prop.Value.GetType());
    foreach (var thingInProp in prop)
    {
        Console.Write("        {0}\n", thingInProp);
    }
}

您可以在下面的图片中看到数字ID。例如，上面的代码成功读取LogFilePeriod等于4，但它无法得到LogFilePeriod属性的ID为4003的事实。我需要ID才能创建集合符合OVAL标准。

我从服务器得到的是这个。身份证在哪里？（顺便说一下，似乎这段代码也从上层路径获得了继承属性。这是正确的吗？）

元数据模式标识符未在ADSI API中显示（System.DirectoryServices.DirectoryEntry包装。但是您可以使用元数据库模式文件作为查找：

C:\WINDOWS\system32\inetsrv\MBSchema.xml

这是您的代码（稍微修改以访问我的本地元数据库）：

XNamespace ns = "x-urn:microsoft-catalog:MetaData_V7";
XDocument schema = XDocument.Load(@"C:\WINDOWS\system32\inetsrv\MBSchema.xml");

using (DirectoryEntry site = new DirectoryEntry("IIS://Localhost/W3SVC/1"))
{
    foreach (PropertyValueCollection prop in site.Properties)
    {
        var schemaProperty = schema.Descendants(ns + "Property")
                .FirstOrDefault(a => 
                     (string)a.Attribute("InternalName") == prop.PropertyName);

        Console.Write("    {0}[ID:{1}] (Type {2})\n", 
            prop.PropertyName,
            schemaProperty.Attribute("ID"),
            prop.Value.GetType());
        foreach (var thingInProp in prop)
        {
            Console.Write("        {0}\n", thingInProp);
        }
    }
}

我假设您使用的是.NET Framework 3.5或更高版本，因此您需要添加引用 System.Xml.Linq。

我应该补充一点，如果您在IIS7 +上使用IIS6兼容层尝试此操作，那么您需要将架构文件从IIS6服务器复制到IIS7盒。

此外，您应该使用托管Microsoft.Web.Administration API来收集有关IIS7 +服务器的配置数据。原因是并非所有IIS6 Metabase对象都映射到IIS7的管理主机配置。 IIS7中也会有一些属性在IIS6包装器中没有可见性，因为没有匹配的类型。

也无法保证IIS的未来版本（例如IIS8）将提供IIS6元数据库兼容性层。

最后，这些ID只是命名属性的数字标识符，即它们不能唯一地标识元数据库中的任何特定对象，这是通过配置数据库路径字符串完成的。

元数据ID的存在主要是为了IIS ABO API的利益，它使用这些ID而不是属性名称。我建议使用字符串属性名称作为标识符，因为正如我之前提到的那样，有新的IIS7对象和属性没有这些ID。

如何在C＃中获取IIS 6 Metabase属性的数字ID？
