在 Azure Functions Http Trigger C# 中找不到类型或命名空间名称 'Queue'

Question

我已经通过 VS Code 创建了 Azure Functions Http Trigger (C#)。

我遇到了一些命名空间错误，我试图通过安装 Azure WebJobs、Azure WebJobs Extensions、System Component DataAnnotation 等几个软件包来解决这些错误，但错误并没有解决。

错误在此图像中 - Click on Me!

文本格式错误： 对于这一行：

[Queue("orders")] IAsyncCollector<Order> orderQueue,

错误：

The type or namespace name 'QueueAttribute' could not be found (are you missing a using directive or an assembly reference?) [pluralsightfuncs]csharp(CS0246)
The type or namespace name 'Queue' could not be found (are you missing a using directive or an assembly reference?) [pluralsightfuncs]csharp(CS0246)

对于这一行：

[Table("orders")] IAsyncCollector<Order> orderTable,

错误：

The type or namespace name 'TableAttribute' could not be found (are you missing a using directive or an assembly reference?) [pluralsightfuncs]csharp(CS0246)
The type or namespace name 'Table' could not be found (are you missing a using directive or an assembly reference?) [pluralsightfuncs]csharp(CS0246)

代码在 https://github.com/licjapodaca/pluralsightfuncs/blob/master/OnPaymentReceived.cs

中可用

我的 .csproj 代码：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <AzureFunctionsVersion>v3</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.Azure.WebJobs" Version="3.0.30" />
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions" Version="4.0.1" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.0.1" />
    <PackageReference Include="System.ComponentModel.Annotations" Version="5.0.0" />
  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>

解决方法之一可以解决上述问题，我已经在我的环境中使用您的代码进行了测试，以消除这些错误并且它按预期正常工作。

正如@Chetan 在中所建议的那样，发现，我们需要安装 Nuget package Microsoft.Azure.WebJobs.Extensions.Storage" Version="4.0.5" 它将消除以上两个错误。

.csproj 文件:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.Storage" Version="4.0.5" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.0.1" />
  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>
