PrintCapabilities.PageMediaSizeCapability Property


Gets a collection of PageMediaSize objects that identify the paper and media sizes that a printer supports.

 property System::Collections::ObjectModel::ReadOnlyCollection<System::Printing::PageMediaSize ^> ^ PageMediaSizeCapability { System::Collections::ObjectModel::ReadOnlyCollection<System::Printing::PageMediaSize ^> ^ get(); };
public System.Collections.ObjectModel.ReadOnlyCollection<System.Printing.PageMediaSize> PageMediaSizeCapability { get; }
member this.PageMediaSizeCapability : System.Collections.ObjectModel.ReadOnlyCollection<System.Printing.PageMediaSize>
Public ReadOnly Property PageMediaSizeCapability As ReadOnlyCollection(Of PageMediaSize)

Property Value

A ReadOnlyCollection<T> of PageMediaSize objects.


The following code example shows how to search for a particular value in the PageMediaSizeCapability.

foreach (PageMediaSize mediaSize in pc.PageMediaSizeCapability)  
        if (mediaSize.PageMediaSizeName == PageMediaSizeName.ISOA4)  
            Console.WriteLine("A4 size is supported");  


Most of the properties of PrintCapabilities that have "Capability" at the end of the name, such as CollationCapability, are collections of values of an enumerated type. But PageMediaSizeCapability and PageResolutionCapability are collections of objects. For the latter two properties, you cannot test for the presence of a particular value by using the Contains method of ReadOnlyCollection<T>. This is because, with reference types, the method returns true only when the memory address of the object passed to it is the same as the address of an object in the collection; that is, they are the same object. Since this will not usually be the case, the method will nearly always return false even if there is an object in the collection with exactly the same values in all its properties as the object passed to the Contains method of ReadOnlyCollection<T>. To determine the contents of the PageMediaSizeCapability, you must enumerate through each of its members, comparing them with the desired value.

If the printer does not support media size selection, the collection is empty.

This property corresponds to the Print Schema's PageMediaSize keyword.
