Azure函数:无法加载DLL'sni.dll'或其依赖项之一:找不到指定的模块.(0x8007007E) [英] Azure functions: Unable to load DLL 'sni.dll' or one of its dependencies: The specified module could not be found. (0x8007007E)

问题描述

尝试在Azure门户中运行此Azure功能，但失败，出现上述标题错误:

Trying to run this Azure Function in Azure portal but fails with above title error:

    using System;
    using System.IO;
    using System.Net;
    using System.Threading.Tasks;
    using Microsoft.AspNetCore.Mvc;
    using Microsoft.Azure.WebJobs;
    using Microsoft.AspNetCore.Http;
    using Microsoft.Extensions.Logging;
    using Microsoft.Extensions.Primitives;
    using Newtonsoft.Json;
    using System.Data.SqlClient;

    public static string Run(HttpRequest req, ILogger log)
    {
        string name="dbconn";
        string conStr = System.Environment.GetEnvironmentVariable(name, EnvironmentVariableTarget.Process);

        if (string.IsNullOrEmpty(conStr)) // Azure Functions App Service naming convention
            conStr = System.Environment.GetEnvironmentVariable($"SQLCONNSTR_{name}", EnvironmentVariableTarget.Process);
        using (SqlConnection conn = new SqlConnection(conStr))
            {
                conn.Open();

            }
        return conStr;

我已经在AzureSQL数据库中添加了ADO.NET ConnectionString:Google搜索显示此问题主要是针对System.Data.SqlClient本地发生的.但是我遇到的问题是azure门户中的主机，我不是从VS发布的，所以不确定如何解决此问题.非常感谢您的帮助.

I've added in the AzureSQL database ADO.NET ConnectionString: Google search shows this issue mostly happening for local in regards to System.Data.SqlClient. But the issue I have is at host in azure's portal, i'm not publishing from VS, so not sure how to fix this. Help really appreciated.

如果我还尝试将System.Data.SqlClient更改为Microsoft.Data.SqlClient，但无法编译:类型或名称空间名称"Data"在名称空间"Microsoft"中不存在(您是否缺少程序集)参考?)

In case I also tried to change System.Data.SqlClient for Microsoft.Data.SqlClient but can't compile: The type or namespace name 'Data' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)

在Azure cli中，我可以看到.net核心为v.2.2.402，不确定是否更新到3.1可能是问题所在?我可以在Windows 10 pc上更新到.Net Core 3.1，但是Azure cli继续显示.net core 2.2.402.我在 stackoverflow 中发布了问题，同时询问如何更新天青的环境.

In Azure cli I can see .net core is v 2.2.402 and not sure if updating to 3.1 could this be the issue? I can update to .Net Core 3.1 on windows 10 pc but Azure cli continues to show .net core 2.2.402. I posted question in stackoverflow question how to also update the azure environment.

非常感谢您的帮助，欢呼！

Thanks a bunch for your help, cheers!

推荐答案

连接字符串似乎有问题.请检查您是否正在使用与此类似的东西:

It looks like something is wrong with the connection string. Please check that you are you using something similar to this:

Server=tcp:{your_server}.database.windows.net,1433;Initial Catalog={your_database};Persist Security Info=False;User ID={your_user};Password={your_password};MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;

对于使用Microsoft.Data.SqlClient(推荐的库)的问题，您需要先将其添加到解决方案中:

For what concern using Microsoft.Data.SqlClient, which is the recommended library, you need to add it to the solution first:

dotnet add package Microsoft.Net.SqlClient
