如何在第二个程序集中查找方法的使用

Question

我正试图为程序集集合绘制依赖矩阵，包括在哪里使用了哪些依赖方法。基本的DLL依赖矩阵很容易，但我发现很难得到方法映射。我一直在使用的工具是jbevain methodbaserrocks .cs.

我要解析的程序集的依赖项正在根据AppDomain.CurrentDomain.GetAssemblies()加载，但我正在获得FileNotFoundException和ReflectionTypeLoadExceptions。

是否有正确的方法来加载引用的程序集?
• 我试过LoadFile, LoadFrom和ReflectionOnlyLoadFrom都有相同的结果。
• 我如何获得使用引用类型的方法的类型?
  • 我可以绕过reflectiontypeloadeexceptions错误的答案从这里，但这些方法是确切的那些我想映射

TestLibraryA.dll

namespace TestLibraryA
{
    public class TestClassA
    {
       public int DoStuff(int a, int b)
       {
          return a + b;
       }
    }
}

TestLibaryB.dll

using TestLibraryA;
namespace TestLibraryB
{
    public class TestClassB
    {
       public int DoStuffAgain()
       {
          TestClassA obj = new TestClassA();
          int ans = obj.DoStuff(3, 5);
          return ans;
       }
       public TestClassA DoOtherStuff()
       {
          TestClassA result = new TestClassA();
          return result;
       }
    }
}

解析器代码应用

public List<string> GetMethods()
{
    List<string> result = new List<string> { };
    Assembly dependencyAssembly = Assembly.LoadFile("TestLibraryA.dll");
    Assembly targetAssembly = Assembly.LoadFile("TestLibaryB.dll");
    Type[] types = targetAssembly.GetTypes();
    // ReflectionTypeLoadExceptions thrown if a dependency type is used
    // NB Not demo'ed in this example
    foreach(var type in types)
    {
        foreach(var method in type.GetMethods())
        {
            // With the above DoStuffAgain() method is returned but DoOtherStuff() is not
            var instructions = MethodBodyReader.GetInstructions(method);
            // FileNotFoundException thrown saying TestLibraryA.dll not loaded
            // the line throwing the error is 
            //  MethodBodyReader(method)
            //    this.body = method.GetMethodBody();
            foreach (var instruction in instructions)
            {
                MethodInfo methodInfo = instruction.Operand as MethodInfo;
                if (methodInfo != null)
                {
                    result.Add(methodInfo.DeclaringType.FullName + "." + methodInfo.Name);
                }
            }
        }
    }
    return result;
}

为了避免这个异常，您需要在加载TestLibaryB

之前添加下面的代码

AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve);
private static Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
{
    if (args.Name == "TestLibaryA...")
    {
        return Assembly.LoadFrom("TestLibaryA's Path");
    }
    return null;
}
