For markup extension types, returns the types of the positional parameters that are supported in a specific markup extension usage for this XamlType.
Assembly: System.Xaml (in System.Xaml.dll)
- Type: System::Int32
The count (arity) of the particular syntax or constructor mode that you want information about.
The input parameterCount is not for requesting the type of a specific positional parameter. It is for specifying the arity of a markup extension usage. Markup extension usage often has multiple "signatures" and uses different parameter arity (count) of positional parameters to differentiate. However, you can configure a schema context to allow duplicate arities and use types of the positional parameters for differentiation. For more information, see SupportMarkupExtensionsWithDuplicateArity. For a specific arity (count), the parameter positions and types can vary. To get the positional type of a specific arity's markup extension usage, you first call specifying the arity count. Then get the item at that position from the returned collection.
