无法在 GetTypes 方法上加载文件或程序集错误

Question

我正在从文件夹中读取 dll 和进程类型。

xxx.dll
xxx.interfaces.dll

当我加载 xxx.dll 并对该程序集调用 GetTypes 时，它会引发异常...

{System.IO.FileNotFoundException: Could not load file or assembly 'xxx.Interfaces, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
File name: 'xxx.Interfaces, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'

=== Pre-bind state information ===
LOG: User = xxx
LOG: DisplayName = xxx.Interfaces, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null
 (Fully-specified)
LOG: Appbase = file:///<myapp>/bin/Debug/
LOG: Initial PrivatePath = NULL
Calling assembly : (Unknown).

LOG: This bind starts in default load context.

LOG: Using host configuration file:

LOG: Policy not being applied to reference at this time (private, custom, partial, or location-based assembly bind).
LOG: The same bind was seen before, and was failed with hr = 0x80070002.
}

似乎它试图从启动应用程序路径中获取依赖 dll，而不是正在加载的程序集。当我检查加载和处理程序集 xxx.Interfaces.dll 时，它工作正常。

Answer 1

尝试使用Assembly.Load() 或Assembly.LoadFrom()。 LoadFrom() 不应该抱怨可能由这个事实引起的依赖关系

加载源上下文允许从未包含在探测中的路径加载程序集，但允许找到并加载对该路径的依赖项，因为路径信息由上下文维护。

示例代码

var assembly = Assembly.LoadFrom(assemblyPath);
var availableTypes = assembly.GetTypes();
