我有一个用 C#（类库）编写的 Visual Studio 编译的小 dll，我想稍后在 Matlab 中使用它。 目前我的目标框架是.Net 7.0（但我也尝试过不同的版本）。 我所包含的代码的最小示例是：
namespace newTest
{
public class Class1
{
public double add(double x, double y)
{
return x + y;
}
}
}
它编译得很好，但是当我想在 Matlab 中加载文件时，它会抛出以下错误：
使用 newTestmatlab 时出错 消息：无法加载文件或程序集“System.Runtime，版本=7.0.0.0， Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' 或其之一 依赖关系。该系统找不到指定的文件。 来源：mscorlib
我知道有类似的问题，我已经尝试了很多不同的解决方案，但到目前为止没有任何效果（在app.config中重新绑定，在Nuget包中包含System.Runtime，不同的.NET sdk版本，安装其他.NET运行时版本）

有人知道如何让它发挥作用吗？我需要在编译或运行时方面做一些事情吗？
我遇到了同样的问题，直到在尝试运行 CLI 后开始收到“尝试加载格式不正确的程序”为止。我的问题是尝试将 x86 库与 x64 应用程序一起使用。仔细检查您的平台目标并确保它们是相同的。
