如何在 Mac OSX 上使用 Net.IBM.Data.Db2？

Question

我有一个使用 Net.IBM.Data.Db2 的 dotnet 核心项目，它在 Windows 和 Linux 上运行良好。我现在尝试使用 Net.IBM.Data.Db2-osx 在 Apple Macbook M3 Pro 上运行它，但出现以下运行时错误：

System.IO.FileNotFoundException: Could not load file or assembly 'IBM.Data.Db2, Version=8.0.0.200, Culture=neutral, PublicKeyToken=7c307b91aa13d208'. The system cannot find the file specified.

我的控制台应用程序包含以下代码。

ConsoleApp1.csproj：

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

    <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>net8.0</TargetFramework>
        <ImplicitUsings>enable</ImplicitUsings>
        <Nullable>enable</Nullable>
    </PropertyGroup>

    <ItemGroup>
        <PackageReference Include="Dapper" Version="2.1.37" />
        <!-- <PackageReference Include="Net.IBM.Data.Db2" Version="8.0.0.200" Condition="$([MSBuild]::IsOsPlatform('Windows'))" /> -->
        <!-- <PackageReference Include="Net.IBM.Data.Db2-lnx" Version="8.0.0.200" Condition="$([MSBuild]::IsOsPlatform('Linux'))" /> -->
        <!-- <PackageReference Include="Net.IBM.Data.Db2-osx" Version="8.0.0.200" Condition="$([MSBuild]::IsOsPlatform('OSX'))" /> -->
        <PackageReference Include="Net.IBM.Data.Db2-osx" Version="8.0.0.200" />
</ItemGroup>

</Project>

程序.cs：

// See https://aka.ms/new-console-template for more information
using IBM.Data.Db2; // note: this is correct, Net.IBM.Data.Db2 does not work
using Dapper;
using System.Data;

Console.WriteLine("Start");

string CONNECTION_STRING = "Server=db.foo.com:50000;Database=foo;UID=foo;PWD=bar;";

var sql = "select * from ST004.students";
using (var connection = new DB2Connection(CONNECTION_STRING))
{
    var rows = await connection.QueryAsync(sql);
    Console.WriteLine(rows);
}

Console.WriteLine("End");

上面抛出以下运行时错误：

Exception has occurred: CLR/System.IO.FileNotFoundException
An unhandled exception of type 'System.IO.FileNotFoundException' occurred in System.Private.CoreLib.dll: 'Could not load file or assembly 'IBM.Data.Db2, Version=8.0.0.200, Culture=neutral, PublicKeyToken=7c307b91aa13d208'. The system cannot find the file specified.'

目前，arm64 上没有对 IBM Data.Db2 的本机支持。您可能需要 docker 容器/VM 来运行您的项目。
