如何在C ++ / CLI中检查对象的类型？ [英] How to check an object's type in C++/CLI?

问题描述

有没有简单的方法来检查对象的类型？我需要一些沿着以下行：

Is there a simple way to check the type of an object? I need something along the following lines:

MyObject^ mo = gcnew MyObject();
Object^ o = mo;

if( o->GetType() == MyObject )
{
    // Do somethine with the object
}
else
{
    // Try something else
}

m使用嵌套的try-catch块寻找 System :: InvalidCastException s感觉丑陋但工作。我将尝试并配置类似上面的代码，看看它是否更快/更慢/可读，但无法解决语法甚至尝试。

At the moment I'm using nested try-catch blocks looking for System::InvalidCastExceptions which feels ugly but works. I was going to try and profile something like the code above to see if it's any faster/slower/readable but can't work out the syntax to even try.

在case任何人的想法，这来自于有一个单一的队列进入一个线程提供数据工作。

In case anyone's wondering, this comes from having a single queue entering a thread which supplied data to work on. Occasionally I want to change settings and passing them in via the data queue is a simple way of doing so.

推荐答案

有时候，我想通过数据队列更改设置和传递它们。 在C ++ / CLI中使用类似于 typeof（MyObject）的方法在C＃中使用下面的代码无耻地复制你的问题和修改...

You can use MyObject::typeid in C++/CLI the same way as typeof(MyObject) is used in C#. Code below shamelessly copied from your question and modified ...

MyObject^ mo = gcnew MyObject();
Object^ o = mo;

if( o->GetType() == MyObject::typeid )
{
    // Do somethine with the object
}
else
{
    // Try something else
}
