无法加载文件或程序集'Microsoft.Azure.Documents.Client-Azure-Table-Api

问题描述：

我正在尝试将Azure Table Api与dotnet核心一起使用，并且不断收到此异常:

I am trying to use Azure Table Api with dotnet core and I keep getting this exception:

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Azure.Documents.Client, Version=1.20.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.

   at Microsoft.Azure.CosmosDB.Table.CloudTableClient..ctor(StorageUri storageUri, StorageCredentials credentials, TableConnectionPolicy connectionPolicy, Nullable`1 desiredConsistencyLevel)
   at Microsoft.Azure.CosmosDB.Table.CloudStorageAccountExtensions.CreateCloudTableClient(CloudStorageAccount account, TableConnectionPolicy connectionPolicy, Nullable`1 consistencyLevel)
   at Testing.Program.Main(String[] args) in /Desktop/Repos/TestingWow/Testing/Program.cs:line 22

显然，这是常见异常消息一个>.我将简单的代码放在 GitHub 上，以防万一.我想我尝试了所有现有的StackOverFlow提示或解决方案，但均未成功.我不确定问题的根源是什么.我在Mac上使用dotnet core 2.1.104.任何帮助将不胜感激.

Apparently this is a common exception message. I put my simple code on GitHub just in case. I think I tried every existing StackOverFlow hint or solution but no success. I am not sure what is the source of my problem. I am using dotnet core 2.1.104 on Mac. Any help would be greatly appreciated.

    class Person : TableEntity
    {
        public string Firstname { get; set; }

            // Create a new customer entity.
            Person customer1 = new Person {Firstname = "Walter@contoso.com"};

            // Create the TableOperation object that inserts the customer entity.
            TableOperation insertOperation = TableOperation.Insert(customer1);

            // Execute the insert operation.
            table.Execute(insertOperation);

经我测试，我认为您应该卸载有关Microsoft.Azure.CosmosDB.Table的所有软件包.

As I have tested, I think you should uninstall all your package about Microsoft.Azure.CosmosDB.Table.

更改为使用WindowsAzure.Storage包在表中添加实体.

Change to use WindowsAzure.Storage package to add entity in table.

此外，您需要设置分区键和行键. 以下代码定义了一个实体类，该实体类使用客户的名字作为行键，并使用姓氏作为分区键.

Also, you need to set the partition key and row key. The following code defines an entity class that uses the customer's first name as the row key and last name as the partition key.

实体的分区和行键在表中唯一标识它.与具有不同分区键的实体相比，具有相同分区键的实体的查询速度更快，但是使用不同的分区键可以提高并行操作的可伸缩性.

An entity's partition and row key uniquely identify it in the table. Entities with the same partition key can be queried faster than entities with different partition keys, but using diverse partition keys allows for greater scalability of parallel operations.

您可以参考以下代码:

在程序中:

public static void  Main(string[] args)
        {
            method().Wait();
        }
        static private async Task method()
        {
            var connectionString = "DefaultEndpointsProtocol=https;AccountName=accountname;AccountKey=xFWWad+YMoW/R7P54ppqGMDs7obGYj3ciEjokt+nkomwYfOh6mUcmcvJLV/puGistsKuGCfOwreCfptK1AwAAQ==;EndpointSuffix=core.windows.net";

            CloudStorageAccount storageAccount = CloudStorageAccount.Parse(connectionString);

            CloudTableClient tableClient = storageAccount.CreateCloudTableClient();

            CloudTable table = tableClient.GetTableReference("table1");

            Person customer1 = new Person("Harp", "Walter");
            customer1.Firstname = "Walter@contoso.com";
            TableOperation insertOperation = TableOperation.Insert(customer1);

            await table.ExecuteAsync(insertOperation);
        }
        class Person : TableEntity
        {
            public Person(string lastName, string firstName)
            {
                this.PartitionKey = lastName;
                this.RowKey = firstName;
            }

            public Person() { }

            public string Firstname { get; set; }
        }

在csproj中:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="WindowsAzure.Storage" Version="9.1.1" />
  </ItemGroup>
