public:
System::Net::PeerToPeer::Collaboration::PeerContactCollection ^ GetContacts();[System.Security.SecurityCritical]
public System.Net.PeerToPeer.Collaboration.PeerContactCollection GetContacts ();[<System.Security.SecurityCritical>]
member this.GetContacts : unit -> System.Net.PeerToPeer.Collaboration.PeerContactCollectionPublic Function GetContacts () As PeerContactCollection傳回
PeerContactCollection，內含遠端對等電腦 ContactManager 中所有的連絡人。
如果連絡人管理員為空白，就會傳回大小為零 (0) 的集合。

例外狀況
此 ContactManager 物件已被處置。
當這個方法嘗試列舉這個對等連絡人集合中的 Peer 時，傳回了無效的值。
範例
下列程式代碼範例說明如何擷取 PeerContactCollection ，代表本機 中包含的 ContactManager聯繫人：
// Displays all contacts and asssociated peer endpoints (PeerEndPoint) in the PeerContactCollection.
private static void DisplayContacts(PeerContactCollection peerContactsCollection)
{
if (peerContactsCollection == null ||

}
else
{
foreach (PeerContact pc in peerContactsCollection)
{
Console.WriteLine("The contact is: {0}", pc.DisplayName);
DisplayEndpoints(pc.PeerEndPoints);
}
}
return;
}
//------------------------------------------------------------------------------------------------------

// Displays all peer end points (PeerEndPoint) in the PeerEndPointCollection.

else
