Question

Jar中的Java代码：

public class FatherClass
{
    public void throwChildAClassException()
    {
        throw new FatherClass.ChildAClassException();
    }

    public class ChildAClassException extends RuntimeException
    {
        private static final long serialVersionUID = 1L;
    }

    public class ChildBClassException extends RuntimeException
    {
        private static final long serialVersionUID = 1L;
    }
}

在Xamarin中

：

当我调用方法ThrowChildAClassException()时，它会将基类抛出为RuntimeException。

↓↓↓代码↓↓↓

try
{
    new FatherClass().ThrowChildAClassException()
}
catch(ChildAClassException childAE)
{
    // debugged but does not reach here
}
catch(ChildAClassException childBE)
{
    // no invoking
}
catch(RuntimeException e)
{
    // debugger approaches here. Isn't it wrong or a bug?
}

那么，我怎样才能获得像ChildAClassException这样的子类？谢谢，全部。

由我修复......

try
{
    new FatherClass().ThrowChildAClassException()
}
catch(RuntimeException e)
{
     // Android.Runtime.Extensions.JavaCast<ChildAClassException>(e);
     // Android.Runtime.Extensions.JavaCast<ChildBClassException>(e);

    string currentExceptionSimpleName = e.Class.SimpleName;
    string classChildAClassExceptionSimpleName = typeof(ChildAClassException).Name;
    string classChildBClassExceptionSimpleName = typeof(ChildBClassException).Name;

    if(currentExceptionSimpleName == classChildAClassExceptionSimpleName)
    {
        // ...
    }
    else if(currentExceptionSimpleName == classChildBClassExceptionSimpleName)
    {
        // ...
    }
}

Jar代码抛出子类，但是xamarin绑定代码抛出基类
