尝试绑定配置：System.ComponentModel.TypeConverter无法加载 [英] Trying to bind configuration: System.ComponentModel.TypeConverter can't be loaded

问题描述

我试图在控制台应用程序中使用ASP.NET Core配置（特别是Microsoft.Extensions.Configuration.Json）。当我调用 IConfigurationRoot.Bind（）时，会为程序集 System引发 FileNotFound 异常。 ComponentModel.TypeConverter 。

根据我的知识 TypeConverter 位于<$ c $系统程序集中的 System.ComponentModel 命名空间，而不是虚构的 System.ComponentModel.TypeConverter 程序集。 p>

这似乎是一个错误。

我的目标是.NET 4.5.2，引用了 System 以下NuGet软件包已安装：

 < package id =Microsoft.Extensions.Configurationversion =1.0.0targetFramework =net452/> 
< package id =Microsoft.Extensions.Configuration.Abstractionsversion =1.0.0targetFramework =net452/> 
< package id =Microsoft.Extensions.Configuration.Binderversion =1.0.0targetFramework =net452/> 
< package id =Microsoft.Extensions.Configuration.FileExtensionsversion =1.0.0targetFramework =net452/> 
< package id =Microsoft.Extensions.Configuration.Jsonversion =1.0.0targetFramework =net452/> 
< package id =Microsoft.Extensions.FileProviders.Abstractionsversion =1.0.0targetFramework =net452/> 
< package id =Microsoft.Extensions.FileProviders.Physicalversion =1.0.0targetFramework =net452/> 
< package id =Microsoft.Extensions.FileSystemGlobbingversion =1.0.0targetFramework =net452/> 
< package id =Microsoft.Extensions.Primitivesversion =1.0.0targetFramework =net452/> 
  

是否有解决方法或其他步骤？

这也不起作用：

  ConfigurationBinder.Bind ，myconfig）; 
  

我的JSON代表字符串属性或者一个 TimeSpan 。

解决方案

我习惯于 TypeConverter 位于系统中。我偷偷摸摸Nu​​Get，发现确实有一个程序集， System.ComponentModel.TypeConverter 作为.NET核心的一部分。安装该软件包解决了我的问题。

I am trying to use ASP.NET Core configuration (specifically Microsoft.Extensions.Configuration.Json) in a console application. When I call IConfigurationRoot.Bind() it throws a FileNotFound exception for the assembly System.ComponentModel.TypeConverter.

To my knowledge TypeConverter is in the System.ComponentModel namespaces in the System assembly, not the fictitious System.ComponentModel.TypeConverter assembly.

This appears to be a bug. Or am I missing something?

I'm targeting .NET 4.5.2, have referenced System, and have the following NuGet packages installed:

<package id="Microsoft.Extensions.Configuration" version="1.0.0" targetFramework="net452" />
<package id="Microsoft.Extensions.Configuration.Abstractions" version="1.0.0" targetFramework="net452" />
<package id="Microsoft.Extensions.Configuration.Binder" version="1.0.0" targetFramework="net452" />
<package id="Microsoft.Extensions.Configuration.FileExtensions" version="1.0.0" targetFramework="net452" />
<package id="Microsoft.Extensions.Configuration.Json" version="1.0.0" targetFramework="net452" />
<package id="Microsoft.Extensions.FileProviders.Abstractions" version="1.0.0" targetFramework="net452" />
<package id="Microsoft.Extensions.FileProviders.Physical" version="1.0.0" targetFramework="net452" />
<package id="Microsoft.Extensions.FileSystemGlobbing" version="1.0.0" targetFramework="net452" />
<package id="Microsoft.Extensions.Primitives" version="1.0.0" targetFramework="net452" />

Is there a workaround or additional steps?

This also does not work:

ConfigurationBinder.Bind(config, myconfig);

It does not seem to matter whether my JSON represents string properties or a struct such as a TimeSpan.

解决方案

I've been used to TypeConverter being in System. I poked around NuGet and found there is indeed an assembly, System.ComponentModel.TypeConverter as part of .NET Core. Installing that package fixed my problem.
