IAassembliesResolver 中永远不会调用 GetAssemblies答案

【问题描述】：

目前我尝试覆盖在 ASP.Net WebApi 2 中解析的程序集。覆盖：

var resolver = new ExtendedAssemblyResolver(new[] { dynAsm });

// Add a list of dynamically loaded assemblies
GlobalConfiguration.Configuration.Services.Replace(typeof(IAssembliesResolver), resolver);

解析器如下所示：

public class ExtendedAssemblyResolver : DefaultAssembliesResolver
{
    private string[] dynamicAssemblies;

    public ExtendedAssemblyResolver(string[] dynamicAssemblies)
    {
        System.Diagnostics.Debugger.Launch();
        this.dynamicAssemblies = dynamicAssemblies;
    }

    public ICollection<Assembly> GetAssemblies()
    {
        var baseAssemblies = base.GetAssemblies();
        var assemblies = new List<Assembly>(baseAssemblies);

        if (dynamicAssemblies != null)
        {
            foreach (var asm in dynamicAssemblies)
            {
                var controllersAssembly = Assembly.LoadFrom(asm);
                baseAssemblies.Add(controllersAssembly);
            }
        }

        return baseAssemblies;
    }
}

问题是，GetAssemblies 永远不会被调用。

我也尝试在我的 Startup 类中替换解析器，但这也无济于事：

public void Configuration(IAppBuilder appBuilder)
{
    // Configure Web API for self-host. 
    HttpConfiguration config = new HttpConfiguration();
    // -- here
}

非常感谢！

【问题讨论】：

您不需要覆盖GetAssemblies 吗？ public override ICollection<Assembly> GetAssemblies
@heinzbeinz 哦，伙计，如果这是问题所在，我今天就辞职了：D 谢谢，只是监督了漂亮的视觉工作室提示：D

【解决方案1】：

你错过了覆盖

public class ExtendedAssemblyResolver : DefaultAssembliesResolver
{
    private string[] dynamicAssemblies;

    public ExtendedAssemblyResolver(string[] dynamicAssemblies)
    {
        System.Diagnostics.Debugger.Launch();
        this.dynamicAssemblies = dynamicAssemblies;
    }

    public override ICollection<Assembly> GetAssemblies()
    {
        var baseAssemblies = base.GetAssemblies();
        var assemblies = new List<Assembly>(baseAssemblies);

        if (dynamicAssemblies != null)
        {
            foreach (var asm in dynamicAssemblies)
            {
                var controllersAssembly = Assembly.LoadFrom(asm);
                baseAssemblies.Add(controllersAssembly);
            }
        }

        return baseAssemblies;
    }
}
