不能在xamarin绑定中使用init构造函数

Question

我试图创建我映射的类的对象。

  [BaseType(typeof(NSObject))]
  interface LibClass
  {
    // @property (readonly) NSString * key;
    [Export("key")]
    string Key { get; }

    // @property (readonly) NSArray * blockNames;
    [Export("blockNames")]
    //[Verify (StronglyTypedNSArray)] //TODO: Verify
    NSObject[] BlockNames { get; }
  }

但代码new LibClass();抛出异常：NSInternalInconsistencyException原因：-init不是类LibClass的有效初始值设定项。

这是生成的构造函数的代码

 [Export ("init")]
 public LibClass () : base (NSObjectFlag.Empty)
 {
   IsDirectBinding = GetType ().Assembly == global::ApiDefinition.Messaging.this_assembly;
   if (IsDirectBinding) {
     InitializeHandle (global::ApiDefinition.Messaging.IntPtr_objc_msgSend (this.Handle, global::ObjCRuntime.Selector.GetHandle ("init")), "init");
   } else {
     InitializeHandle (global::ApiDefinition.Messaging.IntPtr_objc_msgSendSuper (this.SuperHandle, global::ObjCRuntime.Selector.GetHandle ("init")), "init");
   }
 }
