ArrayFromHandleFunc<T>(NativeHandle, Func<NativeHandle,T>)
Creates a strongly-typed C# array from a handle to an NSArray, using a custom factory function.
public static T[] ArrayFromHandleFunc<T>(ObjCRuntime.NativeHandle handle, Func<ObjCRuntime.NativeHandle,T> createObject);public static T?[]? ArrayFromHandleFunc<T>(ObjCRuntime.NativeHandle handle, Func<ObjCRuntime.NativeHandle,T> createObject);static member ArrayFromHandleFunc : ObjCRuntime.NativeHandle * Func<ObjCRuntime.NativeHandle, 'T> -> 'T[]Type Parameters
- T
The element type for the returned array.
Parameters
- handle
- NativeHandle
Pointer (handle) to the unmanaged NSArray object.
- createObject
- Func<NativeHandle,T>
A factory function that creates an instance of T from a native handle.
Returns
A C# array with the values, or null if handle is Zero.
Remarks
Instead of wrapping the results in NSObject instances, this method invokes createObject for each element to create the return value.
var args = NSArray.ArrayFromHandleFunc<int> (someHandle, (x) => (int) x);
