简单的示例程序： var client = new OssClient("http://oss-cn-hangzhou.aliyuncs.com", "xx","xxx"); client.GetObject("xxx", "xxx");

csproj文件如下： `

<PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.1</TargetFramework>
</PropertyGroup>

<ItemGroup>
  <PackageReference Include="Aliyun.OSS.SDK" Version="2.13.0" />
</ItemGroup>

`

在mac可以顺利运行，但在windows报错： Unhandled exception.

Hi, I had the same issue, and problem might be solved by updating .net version you are using to one of the .Net Framework 4.x versions.

So either you should:

  1. Change your project from .NetCore x to .Net Framework 4.x
  2. Or you can use in .Net Standard 2.x version class library

Hope this will help someone else.

2024年了，3年过去了，这个问题依然没有修复…… 看来是真不管issue啊？

如果你是windows系统： 看下构建的是 net framwork 还是 .net or netcore 运行时，

1）如果是 net framework，需要依赖 https://www.nuget.org/packages/Aliyun.OSS.SDK

2）如果是.net 或者 net core 的，需要依赖 https://www.nuget.org/packages/Aliyun.OSS.SDK.NetCore

另外，github上有相应的示例工程，用户可以参考。https://github.com/aliyun/aliyun-oss-csharp-sdk/tree/master/samples
