如何在Azure Functions中包含对外部程序集的引用

问题描述

我尝试了以下操作:

using System;
using Newtonsoft.Json
using Newtonsoft.Linq

public static void Run(string myEventHubMessage, out string document, TraceWriter log)
{
    log.Verbose($"C# Event Hub trigger function processed a message: {myEventHubMessage}");
    dynamic jsonData = JObject.Parse(myEventHubMessage);
    document = jsonData;
}

在Azure门户中单击保存"按钮时，我得到以下信息:

I get the following when I hit the "Save" button in Azure portal:

我还尝试了以下方法:

#r "Newtonsoft.Json"
#r "Newtonsoft.Linq"
using System;

public static void Run(string myEventHubMessage, out string document, TraceWriter log)
{
    log.Verbose($"C# Event Hub trigger function processed a message: {myEventHubMessage}");
    dynamic jsonData = JObject.Parse(myEventHubMessage);
    document = jsonData;
}

在这种情况下，当我在Azure门户中单击保存"按钮时，得到以下信息:

In this case I get the following when I hit the "Save" button in the Azure portal:

从文档中不清楚如何引用这些程序集.我在一个示例中看到语法是使用Newtonsoft.Json"，但这在门户网站中似乎不起作用.有什么建议吗?

It's not obvious from the documentation how to reference these assemblies. I see in one example the syntax is "using Newtonsoft.Json", but this doesn't appear to work in the portal. Any suggestions?

.NET Framework程序集和一些共享" 程序集可以使用以下语法添加:

.NET Framework assemblies and a few "shared" assemblies may be added with the following syntax:

#r "AssemblyName"

因此，对于JSON.NET，您可以使用:

So, for JSON.NET, you can use:

#r "Newtonsoft.Json"

添加引用后，然后，您可以像在常规C#项目/文件中一样添加using语句:

Once the reference is added, then you can add your using statements as you would in a regular C# project/file:

using Newtonsoft.Json;

因此，总而言之，您需要添加对要使用的程序集的引用，并导入该程序集公开的名称空间，以便可以使用其类型.这与您在Visual Studio中执行的操作类似，在Visual Studio中添加程序集引用，然后在需要的地方添加using语句.

So, in summary, you need to add a reference to the assemblies you want to use, and import the namespaces exposed by that assembly so you can use its types. This is similar to what you'd do in Visual Studio, where you add the assembly reference and then add your using statements where you need them.
