Important

Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

Edit

A collection of DNS Service Discovery (DNS-SD) service instances.

Note

DnssdServiceInstanceCollection is not supported and may be altered or unavailable in the future. Instead, use the Windows.Devices.Enumeration API.

Note

Win32 DNS Service Discovery (DNS-SD) APIs are declared in the windns.h header. For example, the Win32 APIs for announcing and discovering services are DnsServiceRegister and DnsServiceBrowse.

Windows requirements

Device family	Windows 10 (introduced in 10.0.10240.0)
API contract	Windows.Foundation.UniversalApiContract (introduced in v1.0)

Remarks

Your code does not create a DnssdServiceInstanceCollection directly. Instead, handle the DnssdServiceWatcher.EnumerationCompleted event. When that event is triggered, the second argument to the event handler is a pointer to a DnssdServiceInstanceCollection object that contains information about the discovered service instances.

Properties

Size	Gets the number of items in the collection Note DnssdServiceInstanceCollection is not supported and may be altered or unavailable in the future. Instead, use the Windows.Devices.Enumeration API.

Methods

First()	Gets an iterator that is initialized to refer to the first item in the instance collection. Note DnssdServiceInstanceCollection is not supported and may be altered or unavailable in the future. Instead, use the Windows.Devices.Enumeration API.
GetAt(UInt32)	Gets the DnssdServiceInstance at a given index into the DnssdServiceInstanceCollection. Note DnssdServiceInstanceCollection is not supported and may be altered or unavailable in the future. Instead, use the Windows.Devices.Enumeration API.
GetMany(UInt32, DnssdServiceInstance[])	Gets multiple DnssdServiceInstance objects from a DNS-SD service instance collection. Note DnssdServiceInstanceCollection is not supported and may be altered or unavailable in the future. Instead, use the Windows.Devices.Enumeration API.
IndexOf(DnssdServiceInstance, UInt32)	Gets a value indicating whether a given DnssdServiceInstance is at the specified index in this service instance collection. Note DnssdServiceInstanceCollection is not supported and may be altered or unavailable in the future. Instead, use the Windows.Devices.Enumeration API.
