我可以从 HashCode 中获取对象吗？

Question

他们有什么方法可以从哈希码中获取对象吗？？？

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

所以请帮助我找到实际绑定警告即将到来的对象或样式或控件模板？或者帮助我通过哈希码找到警告即将到来的对象。

以下绑定警告即将到来。

如何获得这些警告的来源？谁能帮帮我？？？

Answer 1

散列函数是一种方式，你向它传递一个输入值，它总是会输出相同的值。

所以不，你不能逆向，即你不能反过来（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，因此存在哈希码计算固有的信息丢失。

也就是说，您质疑X-Y problem 的气味。我认为您想调试为什么会在 wpf 中发生问题，并作为一种方法来确定您正在尝试使用哈希码对其进行调试。

解决这个问题的一种方法是找出所有对象的hashcode，并将它们与攻击性hashcode进行比较。

您可以使用以下代码来做到这一点：

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;
}

并如下执行，如this answer中所述：

    string storyBoardName = GetStoryBoardNameByHashCode(65981734);

另一种可能性是Begin 部分缺少Stop，如this answer 中所述

另外，您可能想看看this ticket on DevExpress。

哈希码是一种方式，您可以从对象中获取哈希值，但反之则不行。
