ArrayFromHandleFunc<T>(NativeHandle, Func<NativeHandle,T>)
Returns a strongly-typed C# array of the parametrized type from a handle to an NSArray.
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
Parameter type, determines the kind of array returned.
Parameters
- handle
- NativeHandle
Pointer (handle) to the unmanaged object.
- createObject
- Func<NativeHandle,T>

An C# array with the values.
Remarks
Use this method to get a set of NSObject arrays from a handle to an NSArray. Instead of wrapping the results in NSObjects, the code invokes your method to create the return value.
int [] args = NSArray.ArrayFromHandle<int> (someHandle, (x) => (int) x);
