    I am Working on the Xamarin.MAc Project. In my project I need to Use Objective C Code so I going to bind and use in my Xamarin project.

    I am using Objective sharpie for generating the Interface and enum file. that's working fine but i am not able to generate  the .dll file.

    This is my .cs files,



  using System;
    using System.Drawing;
    using MonoMac.Foundation;
    using MonoMac.AppKit;
    using MonoMac.ObjCRuntime;
    using System.Collections.Generic;


    namespace BLVirtualDrive {

        // @interface BaseItemModel : NSObject
        [BaseType (typeof (NSObject))]
        interface BaseItemModel {

            // @property (nonatomic, strong) NSString * name;
            [Export ("name", ArgumentSemantic.Retain)]
            string Name { get; set; }

            // @property unsigned long long id;
            [Export ("id")]
            ulong Id { get; set; }

            // @property unsigned long long parentId;
            [Export ("parentId")]
            ulong ParentId { get; set; }
        }

        // @interface FileModel : BaseItemModel
        [BaseType (typeof (BaseItemModel))]
        interface FileModel {

            // @property unsigned long long currentBufferSize;
            [Export ("currentBufferSize")]
            ulong CurrentBufferSize { get; set; }

            // @property unsigned long long totalFileSize;
            [Export ("totalFileSize")]
            ulong TotalFileSize { get; set; }

            // @property unsigned long long startByte;
            [Export ("startByte")]
            ulong StartByte { get; set; }

            // @property unsigned long long endByte;
            [Export ("endByte")]
            ulong EndByte { get; set; }

我试过这样的命令行工具 /Library/Frameworks/Xamarin.Mac.framework/Versions/1.10.0.18/bin/bmac -oBLVirtualDrive.dll --tmpdir=/tmp -baselib=/Library/Frameworks/Xamarin.Mac .framework/Versions/1.10.0.18/lib/mono/XamMac.dll -r=System.Drawing IBLVirtualDrive.cs -s=IBLVirtualDriveenums.cs --compiler=mcs --new-style 我收到这样的错误 BI1018： bmac：属性 BLVirtualDrive.BaseItemModel.Name 上没有 [Export] 属性我在命令行字段中遗漏的任何内容。

也许您需要尝试添加 Xamarin.Mac.dll 而不是 XamMac.dll，并从源中删除 MonoMac。

using Foundation;
using AppKit;
using ObjCRuntime;

此外，在 Extras.cs 文件的顶部添加以下代码：

using System;

[AttributeUsage (AttributeTargets.Method)]
public sealed class MonoPInvokeCallbackAttribute : Attribute {
     public MonoPInvokeCallbackAttribute (Type t) {}
}
