【问题描述】：

我正在使用以下代码以编程方式为 IIS 6 (Windows Server 2003R2) 创建应用程序池，但在尝试设置 ManagedPipelineMode 时遇到错误

尝试 1

        string metabasePath = @"IIS://localhost/W3SVC/AppPools";

        DirectoryEntry apppools = new DirectoryEntry(metabasePath);
        DirectoryEntry newpool = apppools.Children.Add(AppPoolName, "IIsApplicationPool");
        newpool.Properties["managedRuntimeVersion"].Value = "v4.0";
        newpool.InvokeSet("ManagedPipelineMode", new Object[] { 0 }); //exception thrown on this line
        newpool.Properties["Enable32BitAppOnWin64"].Value = true;
        if (!string.IsNullOrEmpty(username))
        {
            newpool.Properties["AppPoolIdentityType"].Value = 3;
            newpool.Properties["WAMUserName"].Value = username;
            newpool.Properties["WAMUserPass"].Value = password;
        }
        newpool.CommitChanges();

尝试 2

        string metabasePath = @"IIS://localhost/W3SVC/AppPools";

        DirectoryEntry apppools = new DirectoryEntry(metabasePath);
        DirectoryEntry newpool = apppools.Children.Add(AppPoolName, "IIsApplicationPool");
        newpool.Properties["managedRuntimeVersion"].Value = "v4.0";
        newpool.Properties["ManagedPipelineMode"][0] = 0; //exception thrown on this line
        newpool.Properties["Enable32BitAppOnWin64"].Value = true;
        if (!string.IsNullOrEmpty(username))
        {
            newpool.Properties["AppPoolIdentityType"].Value = 3;
            newpool.Properties["WAMUserName"].Value = username;
            newpool.Properties["WAMUserPass"].Value = password;
        }
        newpool.CommitChanges();

无论哪种方式都会引发相同的异常。

例外：

Exception from HRESULT: 0x80005006
    at System.DirectoryServices.Interop.UnsafeNativeMethods.IAds.PutEx(Int32 lnControlCode, String bstrName, Object vProp)
    at System.DirectoryServices.PropertyValueCollection.OnClearComplete()
    at System.DirectoryServices.PropertyValueCollection.set_Value(Object value)

【解决方案1】：

事实证明，我的问题比我想象的更根本。首先，IIS 6 不支持集成管道模式，所以开关ManagedPipelineMode 甚至都不存在。此外，Enable32BitAppOnWin64 也不以这种方式存在，要打开该功能，必须运行命令 (https://web.archive.org/web/20160313115849/http://extended64.com/blogs/rhoffman/archive/2005/05/10/482.aspx)
