Matlab 无法加载 .NET 程序集

发布于 2024-11-26 07:35:16 字数 692 浏览 1 评论 0原文

当我尝试通过键入以下内容在 Matlab 中加载我的 .NET 程序集 foo.dll 时，

asm = NET.addAssembly('fullpath\foo.dll');

出现以下错误：“无法加载文件或程序集 'file:///fullPath\foo.dll' 或其依赖项之一。此程序集由比当前加载的运行时更新的运行时构建，无法加载来源：mscorlib HelpLink：“

我有 Matlab R2010a，并且尝试为 .NET Framework 4.0 和 .NET Framework 构建程序集。 3.0没有成功。

编辑

我做了几次测试，现在也许我已经部分发现了这个问题。在上面的示例中，我尝试通过提供完整路径来添加私有程序集。然后我记得之前也在 GAC 中注册了相同的程序集（针对 .NET 4.0）（通过 gacutil /i foo.dll 命令）。因此，我从 GAC 中删除了该程序集 (gacutil /u foo)，现在至少我能够添加针对 .NET 3.0 的私有程序集，但如果我想针对 .NET 4.0，则仍然不能添加该程序集。

我认为之前，当我尝试为 .NET 3.0 添加私有程序集时，Matlab 仍在尝试为 GAC 中安装的 .NET 4.0 添加程序集，因为存在一些冲突。但是，我仍然不明白为什么我不能使用 .NET 4.0 。

When I try to load in Matlab my .NET assembly foo.dll by typing:

asm = NET.addAssembly('fullpath\foo.dll');

I get the following error: "Could not load file or assembly 'file:///fullPath\foo.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. Source: mscorlib HelpLink:"

I've Matlab R2010a and I tried to build the assembly both for .NET framework 4.0 and .NET framework 3.0 with no success.

EDIT

I did several tests and now maybe I've partly discovered the problem. In the above example I was trying to add a private assembly by giving the full path. I then remembered to have also previously registered the same assembly (targeted for .NET 4.0) in the GAC (through the gacutil /i foo.dll command). Hence I removed the assembly from the GAC (gacutil /u foo) and now at least I'm able to add the private assembly targeted for .NET 3.0 but still not if I want to target .NET 4.0.

I presume that before, when I was trying to add a private assembly for .NET 3.0, Matlab was still trying to add the assembly for .NET 4.0 installed in the GAC, because of some conflict.
However, I still do not understand why I cannot use .NET 4.0 .

我无法重现该错误。这是我使用的示例：

MyClass.cs

using System;
namespace ClassLibraryTest
{
    public class MyClass
    {
        public static double add(double x, double y)
        {
            return x + y;
        }
    }
}

MATLAB

>> NET.addAssembly('C:\path\to\ClassLibraryTest.dll');
>> ClassLibraryTest.MyClass.add(1,2)
ans =
     3

我尝试了不同的.NET 目标框架 4.0/3.5/3.0，它们都工作正常。请注意，程序集一旦加载就无法卸载，释放 .NET 资源的唯一方法是重新启动 MATLAB...

I can't reproduce the error. This is the example I used:

MyClass.cs

using System;
namespace ClassLibraryTest
{
    public class MyClass
    {
        public static double add(double x, double y)
        {
            return x + y;
        }
    }
}

MATLAB

>> NET.addAssembly('C:\path\to\ClassLibraryTest.dll');
>> ClassLibraryTest.MyClass.add(1,2)
ans =
     3

I tried different .NET target frameworks 4.0/3.5/3.0, and they all worked fine. Note that you can't unload an assembly once loaded, and the only way to release the .NET resources is to restart MATLAB...
