How can I use start script change IIS Application pool pipeline mode - iis

Question

I used a web role.
I just wonder if I can use Start script for my project to change the pipeline mode to classic.
I can use C# code achieve that, but I prefer to use cmd, The problem I meet here is how can I get the applicationPool name by cmd?
Here is my C# code:
{
using (ServerManager serverManager = new ServerManager())
{
Site site = serverManager.Sites[RoleEnvironment.CurrentRoleInstance.Id + "_Web"];
Configuration config = serverManager.GetApplicationHostConfiguration();
string AppPoolName = site.Applications[0].ApplicationPoolName;
ConfigurationSection applicationPoolsSection = config.GetSection("system.applicationHost/applicationPools");
ConfigurationElementCollection applicationPoolsCollection = applicationPoolsSection.GetCollection();
ConfigurationElement addElement = FindElement(applicationPoolsCollection, "add", "name", AppPoolName);
if (addElement == null) throw new InvalidOperationException("Element not found!");
addElement["managedPipelineMode"] = #"Classic";
serverManager.CommitChanges();
return base.OnStart();
}
}
private static ConfigurationElement FindElement(ConfigurationElementCollection collection, string elementTagName, params string[] keyValues)
{
foreach (ConfigurationElement element in collection)
{
if (String.Equals(element.ElementTagName, elementTagName, StringComparison.OrdinalIgnoreCase))
{
bool matches = true;
for (int i = 0; i < keyValues.Length; i += 2)
{
object o = element.GetAttributeValue(keyValues[i]);
string value = null;
if (o != null)
{
value = o.ToString();
}
if (!String.Equals(value, keyValues[i + 1], StringComparison.OrdinalIgnoreCase))
{
matches = false;
break;
}
}
if (matches)
{
return element;
}
}
}
return null;
}
}
So How can I do that ?

If the pool name is the only problem you are facing, try using appcmd for listing all available pools:
appcmd.exe list apppool /text:*
This should give you all apppools available on IIS with the app names (provided you have enough rights).
