FromNSObjects(IntPtr, INativeObject[])

Creates an NSArray from a C# array of objects implementing INativeObject, using the first count elements.

public static Foundation.NSArray FromNSObjects(IntPtr count, params ObjCRuntime.INativeObject?[]? items);

static member FromNSObjects : nativeint * ObjCRuntime.INativeObject[] -> Foundation.NSArray

Parameters

The type of objects in the array, which must implement INativeObject.

Parameters

items: T[,]

A two-dimensional array of objects. If null, returns null.

Returns

NSArray

A new NSArray containing nested NSArrays, one for each row of the 2D array. Returns null if items is null.

Remarks

Type Parameters

T

The type of objects in the array, which must implement INativeObject.

Parameters

Returns

NSArray

A new NSArray containing the converted objects. Returns null if items is null.

Exceptions

ArgumentNullException
