public virtual System.Threading.Tasks.Task<Foundation.INSItemProviderReading> LoadObjectAsync (ObjCRuntime.Class aClass);

abstract member LoadObjectAsync : ObjCRuntime.Class -> System.Threading.Tasks.Task<Foundation.INSItemProviderReading>
override this.LoadObjectAsync : ObjCRuntime.Class -> System.Threading.Tasks.Task<Foundation.INSItemProviderReading>

參數

aClass

Class

傳回

Task<INSItemProviderReading>

表示非同步 LoadObject 作業的工作。 TResult 參數的值的類型為 System.Action < Foundation.INSItemProviderReading，Foundation.NSError > 。

屬性

IntroducedAttribute

備註

LoadObjectAsync 方法適合與 C# 非同步搭配使用，方法是將控制項傳回給代表作業之 Task 的呼叫端。

即將加入。
