c# - 从 OSX (Mac) 上的控制台应用程序访问 Azure 存储帐户

Question

我正在使用适用于 Mac 的 VS 2017 社区版编写代码，并尝试访问 Azure 存储帐户上的 Blob。但是，我遇到了异常，如下面的代码所示。

WindowsAzure.Storage版本是9.1.1

using System;
using Microsoft.Azure;
using Microsoft.WindowsAzure.Storage;

namespace storageaccount
{
    class MainClass
    {
        public static void Main(string[] args)
        {
            var storageAccount = CloudStorageAccount.Parse(
                CloudConfigurationManager.GetSetting("StorageConnection"));

            //var blobClient = storageAccount.CreateCloudBlobClient();

            //var container = blobClient.GetContainerReference("images");

               //container.CreateIfNotExists(Microsoft.WindowsAzure.Storage.Blob.BlobContainerPublicAccessType.Blob);

        //Console.ReadKey();
        }
    }
}

上述代码抛出异常:

System.DllNotFoundException: fusion.dll
  at at (wrapper managed-to-native) Microsoft.Azure.NativeMethods.CreateAssemblyCache(Microsoft.Azure.NativeMethods/IAssemblyCache&,int)
  at Microsoft.Azure.NativeMethods.GetAssemblyPath (System.String name) [0x00037] in <bcbac5dcfbdd47eabe8212983b7d996d>:0

代码有什么问题吗？我正在使用 Nuget 包访问云存储帐户。从抛出的异常来看，尚不清楚 OSx 是否支持这一点。

感谢任何帮助。

附加信息:我在创建新项目时看到 VS 2017(适用于 Mac)中有两个项目选项。1..Net核心控制台应用程序2. .Net 控制台应用程序(在 .Net 选项下)- 它针对什么运行？

谢谢

正如您提到的，Microsoft.WindowsAzure.ConfigurationManager 是.net 框架包，它与.net core 平台不兼容。

I am still looking for information on how to read app.config for .Net application on Mac

您可以使用System.Configuration.ConfigurationManager来做到这一点。

 var storeageString = ConfigurationManager.AppSettings["storagestring"];

应用程序配置

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="storagestring" value ="Test string"/>
  </appSettings>
</configuration>

另一种方法是您可以将 appsettings.json 添加到 .NET Core 控制台应用程序。

All that’s required is to add the following NuGet packages and an appsettings.json file.

• Microsoft.Extensions.Configuration

• Microsoft.Extensions.Configuration.FileExtensions

• Microsoft.Extensions.Configuration.Json

演示代码

var builder = new ConfigurationBuilder()
            .AddJsonFile("appsettings.json");
IConfigurationRoot configuration = builder.Build();
var connectionString = configuration["StorageConnection"];
Console.WriteLine(connectionString);

appsettings.json 文件:

{
    "StorageConnection": "Test Connection string"
}
