Question

他们是否可以通过哈希码获取对象???

实际上问题是我在我们的应用程序中找到了一些绑定警告＆amp;每个警告都有相同的源哈希码。我尝试按源名称搜索目标名称，但没有找到这样的东西。

那么请帮助我找到对象或样式或控制模板，其中实际绑定警告即将到来？或者帮助我通过其哈希码找到警告所针对的对象。

以下约束警告即将到来。

如何获得这些警告的来源？任何人都可以帮助我吗？

Answer 1

哈希函数是一种方法，你传递一个输入值，它将始终输出相同的值。

所以不，你不能反过来，即你不能反过来做（从哈希生成对象）。哈希函数用于将任意大小的数字数据映射到固定大小的数字数据，因此存在计算哈希码所固有的信息丢失。

那就是说，你质疑X-Y problem的气味。我想你想调试wpf中出现问题的原因，作为一种解决问题的方法，你试图使用哈希码对其进行调试。

解决此问题的一种方法是找出计算所有对象的hashcode，并将每个对象与攻击性hashcode进行比较。

您可以使用以下代码执行此操作：

private string GetStoryBoardNameByHashCode(int hashCode)
{
    foreach (DictionaryEntry resource in Resources)
    {
        if (resource.Value is Storyboard)
        {
            if (resource.GetHashCode() == hashCode)
                return ((Storyboard) resource.Value).Name;
        }
    }
    return String.Empty;
}

并执行如下所示，如this answer中所述：

    string storyBoardName = GetStoryBoardNameByHashCode(65981734);

另一种可能性是Stop部分缺少Begin，如this answer

中所述

另外，您可能需要查看this ticket on DevExpress。

哈希码是一种方式，你可以从一个对象获得一个哈希，但不能反过来。

我可以从HashCode获取对象吗？
