来自的不可调度异常MethodInfo.调用

问题不在代码中。
在“调试/异常”菜单中,删除所有检查。
应该有用。

在程序.cs

Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);

try
{
    Application.Run(new Form1());
}
    catch (Exception ex)
{
}

问题不在于你展示的代码。

我试过这个:

void Main()
{
    Test instance = new Test();
    object[] parameters = new object[] { null };

    MethodInfo method = typeof(Test).GetMethod("Register");

    try
    {
        method.Invoke(instance, parameters);
    }
    catch
    {
        Console.Out.WriteLine("Exception");
    }
}

interface ITest { }
interface IWindow { }
class Plugin { }

class Test : Plugin, ITest
{
    public void Register(IWindow window)
    {
        throw new Exception("Hooah");
    }
}

它按预期打印了“例外”。你需要给我们看更多的代码。

catch(Exception ex)
{
    Console.Out.WriteLine(ex.GetType().Name + ": " + ex.Message);
}

我认为问题在于,您可能需要一个特定的异常类型 IOException 或者别的什么,但实际上 MethodInfo.Invoke() TargetInvocationException :

try
{
     registrator.Method.Invoke(instance, parameters);
}
catch (TargetInvocationException tie)
{
    // replace IOException with the exception type you are expecting
    if (tie.InnerException is IOException)
    {
        registrator.FailureType = RegistratorFailureType.ExceptionInRegistrator;
        registrator.Exception = tie.InnerException;
    }
    else
    {
        // decide what you want to do with all other exceptions — maybe rethrow?
        throw;
        // or maybe unwrap and then throw?
        throw tie.InnerException;
    }
}
