我正在使用 Enterprise Library 6 和 Unity v.3.5.0.0

出现以下错误：

无法从程序集“Microsoft.Practices.EnterpriseLibrary.Common，版本=6.0.0.0，Culture=neutral，PublicKeyToken=31bf3856ad364e35”加载类型“Microsoft.Practices.EnterpriseLibrary.Common.Configuration.Manageability.ConfigurationSectionManageabilityProviderAttribute”。

当使用此代码通过使用一组规则和约定（通过约定注册）向容器自动注册多种类型时

container.RegisterTypes(
    AllClasses.FromLoadedAssemblies()
    .Where(x => (x.IsPublic == true) &&
    (x.GetInterfaces().Any() == true) &&
    (x.IsAbstract == false) &&
    (x.IsClass == true) &&
    x.Namespace == "Company.Project.Data.DA.NW" ),
    WithMappings.FromAllInterfaces, type => (container.Registrations.Select(x => x.RegisteredType)
    .Any(r => type.GetInterfaces().Contains(r) == true) == true) ? WithName.TypeName(type) : WithName.Default(type),
    WithLifetime.Transient);

更新：

类型：

Microsoft.Practices.EnterpriseLibrary.Common.Configuration.Manageability.ConfigurationSectionManageabilityProviderAttribute

不再是 EntLib 6 的一部分，而是在 Entlib 5 中。

堆栈跟踪：

这不是真正的解决方案，而是一种解决方法：

我只是替换了第一个参数：

AllClasses.FromLoadedAssemblies()
    .Where(x => (x.IsPublic == true) &&
    (x.GetInterfaces().Any() == true) &&
    (x.IsAbstract == false) &&
    (x.IsClass == true) &&
    x.Namespace == "Company.Project.Data.DA.NW" )

并将其替换为自定义函数（assFilter 是具有简单程序集名称的字符串列表，而 classFilter 是名称空间列表）

var filteredAssemblies = AppDomain.CurrentDomain.GetAssemblies().Where(a => assFilter.Contains(a.FullName.Split(',')[0]));

    List<Type> allClasses = new List<Type>();
    foreach (var assembly in filteredAssemblies)
    {
        var classArray = assembly.GetTypes().Where(t => t.IsPublic &&
            !t.IsAbstract &&
            t.IsClass == true &&
            classFilter.Contains(t.Namespace));
        if (classArray != null && classArray.Count() > 0)
            allClasses.AddRange(classArray);
    }
