为什么我的 UWP 应用无法调用 Type.GetProperties 方法? [英] Why my UWP app can't call to Type.GetProperties method?

问题描述

我需要在 UWP 平台中访问 Type.GetProperties，但我的 Type 类滞后于该方法.

I need to access to Type.GetProperties in my UWP platform, but my Type class lags of that method.

在我看来，这是因为我们在 UWP 中使用了子集方法，但是在尝试查找信息时，我发现了这一点:Type.GetProperties() 在 Release 中不起作用，因此该方法确实存在于 UWP 中.

In my mind it's because of the subset methods we have in UWP, but trying to find information, I found this: Type.GetProperties() doesn't work in Release so that method really exists in UWP.

如果我去看Type的定义，第一行是这样的:

If I go to the definition of Type, the first lines are like this:

#region Assembly System.Runtime, Version=4.0.20.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
// C:\Users\JoséÁngel\.nuget\packages\System.Runtime\4.0.20\ref\dotnet\System.Runtime.dll
#endregion

也许我的 nuget 配置有问题?

Maybe there is something wrong in my nuget configuration?

项目的条件编译符号为:

The conditional compilation symbols of the project are:

NETFX_CORE;WINDOWS_UWP;CODE_ANALYSIS

我尝试使用和不使用使用 .NET Native 工具链编译"选项.

I tried with and without "Compile with .NET Native tool chain" option.

目标是通用 Windows

The Target is Universal Windows

目标版本为:Windows 10 (10.0; Build 10586)最低版本为:Windows 10 (10.0; Build 10240)

The Target version is: Windows 10 (10.0; Build 10586) The Min version is: Windows 10 (10.0; Build 10240)

但我也尝试过最小版本:Windows 10 (10.0; Build 10586)

but I also tried with Min version: Windows 10 (10.0; Build 10586)

在 NuGET 中，项目只有 Microsoft.NETCore.UniversalWindowsPlatform v5.0.0

and in NuGET, the project only has Microsoft.NETCore.UniversalWindowsPlatform v5.0.0

推荐答案

如链接问题的答案中所述，将您的类型添加到 .net 本机动态列表，然后使用 *yourthing*.GetType().GetTypeInfo().DeclaredProperties.

Add your type to the .net native dynamic list as explained in the linked question's answer, and then use *yourthing*.GetType().GetTypeInfo().DeclaredProperties.
