如何在单击按钮时将值从字典复制到另一个字典？

how to copy values from a dictionary to another on a button click?

推荐答案

最简单的方法：

Simplest way:

Dictionary<mykeyclass,> d2 = d1.ToDictionary(k => k.Key, k => k.Value);

如果您只需要指定一些记录，请在之前添加Where调用ToDictionary。

If you need to specify just some of the records, add a Where call in there before the ToDictionary.

猜猜你想要对单个对象进行处理而不是对同一对象的引用。

Guess That you want work on individual objects not on references to the same object.

Dictionary<string, string> A = new Dictionary<string, string>();
Dictionary<string, string> A1 = new Dictionary<string, string>(A);

如果你想让他们引用同一个对象：

if you want them references to the same object:

Dictionary<string, string> A = new Dictionary<string, string>();
Dictionary<string, string> A1 = A;
