Type of Outlook Item

[PIT]

Hi,

is there a way to know which type of item is in a Folder? Also mail,
document or post.

I use c#.

Thanks for tip.

Hi

We can use reflection as below.
The item's Class property will be one of the enum type Outlook.OlItemType.

private void button1_Click(object sender, System.EventArgs e)
{
Outlook.Application olApp = new Outlook.ApplicationClass();
Outlook.MAPIFolder mi =
olApp.GetNamespace("MAPI").GetDefaultFolder(Outlook.OlDefaultFolders.olFolde
rInbox);
foreach (Outlook.MAPIFolder o in mi.Folders )
{
if (o.Name=="test" )
{
mi = o;
break;
}
}
foreach(object o in mi.Items)
{
Outlook.OlItemType oo
=(Outlook.OlItemType)o.GetType().InvokeMember("Class",System.Reflection.Bind
ingFlags.GetProperty,null,o,new object[]{});
Console.WriteLine(oo.ToString());
}
}

Hi Peter,

thanks for your answer. I have found another way:

Outlook._PostItem oP = oo as Outlook._PostItem;
if(oP!=null) {....}
else
{
Outlook._MailItem oM = oo as Outlook._MailItem;
if(oM!=null) {....}
}

which if these way has better performance. I must loop along items?

Hi

Yes, that is an alternative too.
I guess we just need to call InvokeMember on Certain Item one time.

And then use a switch statement to cast the item to certain type directly.
If you still have any concern, please feel free to post here.
