我可以从 HashCode 获取对象吗？

Question

他们有什么办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代码。我尝试通过源名称和目标名称进行搜索，但没有找到这样的东西。

所以请帮我找到实际绑定警告即将到来的对象或样式或控制模板？或者帮助我通过其哈希代码找到警告即将到来的对象。

以下绑定警告即将到来。

我怎样才能得到这些警告的来源？谁能帮我？？？

Answer 1

散列函数是一种方法，您将输入值传递给它，它会始终输出相同的值。

所以不，你不能倒退，即你不能反过来做（从哈希生成对象）。散列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，因此存在散列码计算固有的信息丢失。

也就是说，你质疑XY 问题的味道。我认为您想调试问题发生的原因wpf，并作为一种确定您正在尝试使用哈希码对其进行调试的方法。

解决此问题的一种方法是找出hashcode所有对象的计算，并将它们中的每一个与进攻性hashcode.

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;
}

并按如下方式执行它，如本答案中所述：

    string storyBoardName = GetStoryBoardNameByHashCode(65981734);

另一种可能是失踪Stop的Begin部分，如在提到这个答案

此外，您可能想在 DevExpress 上查看这张票。
