奇怪的Assembly.Load错误尝试加载使用C#代码提供程序编译的程序集

Cha*_*ion 6 c# nunit unit-testing assembly.load csharpcodeprovider

我正在尝试使用C#代码提供程序从我的代码编译程序集.

当我使用compilerResult.CompiledAssembly访问已编译的程序集时,一切正常.但是,当我改为执行Assembly.Load(路径)时,我得到以下异常:

System.IO.FileLoadException:无法加载文件或程序集"C:\ Users\Name\Desktop\output.dll"或其依赖项之一.给定的程序集名称或代码库无效.(HRESULT异常:0x80131047)

我究竟做错了什么?

这是代码:

[Test]
public static void CompileCodeIntoAssembly()
{
    var code = "public class X { }";
    var file = Path.Combine(
        Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "output.cs");
        File.WriteAllText(file, code);

    using (var provider = new CSharpCodeProvider())
    {
        var parameters = new CompilerParameters
        {
            GenerateInMemory = false, // we want the dll saved to disk
            GenerateExecutable = false,
            CompilerOptions = "/target:library /lib:\"" + typeof(Class2).Assembly.Location + "\"",
            OutputAssembly = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "output.dll"),
        };
        parameters.ReferencedAssemblies.AddRange(new[]
        {
            "System.dll",
            typeof(Class1).Assembly.Location,
        });

    var compilerResult = provider.CompileAssemblyFromFile(parameters, file);
    if (compilerResult.Errors.Count > 0)
    {
        compilerResult.Errors.Cast<object>().ToDelimitedString(Environment.NewLine).Dump();
        throw new Exception();
    }

    var assembly = Assembly.Load(parameters.OutputAssembly);
    //var assembly = compilerResult.CompiledAssembly; // this method works
    var type = assembly.GetTypes().Single(t => t.Name == "X");
}

.LoadFile如果要从文件路径加载程序集,则需要使用该方法:

var assembly = Assembly.LoadFile(parameters.OutputAssembly);

根据文档,方法.Load:

根据其名称的长形式加载程序集.

它需要一个程序集名称,比如 SampleAssembly, Version=1.0.2004.0, Culture=neutral, PublicKeyToken=8744b20f8da049e3
