[英]Referencing a C# object by calculation
I have 8 picture boxes, named p1 through p8. 我有8个图片框,分别命名为p1到p8。
I would like to change the backcolor of one of those picture boxes, depending on the result of a calculation. 我想根据计算结果更改其中一个图片框的背景色。
I can create a string beginning with the letter 'p' and affix the calculated number to that string. 我可以创建一个以字母“ p”开头的字符串,并将计算得出的数字附加到该字符串上。
I am looking for a clever way to reference a picture box with this string (eg. "p4"). 我正在寻找一种聪明的方法来引用带有此字符串的图片框(例如“ p4”)。 My question is, is this possible?
我的问题是,这可能吗?
If you really want to refer to them by a string like p4
then put them in a dictionary 如果您真的想通过
p4
类的字符串来引用它们,则将它们放入字典中
var dict = new Dictionary<string,PictureBox>();
dict.add("p1",myP1dict);
dict.add("p2",myP2dict);
// etc
dict["p2"].BackgroundColor = newColor;
More likely, you could just put them in an array 您更有可能将它们放在一个数组中
var arr = new PictureBox[8]
arr[0] = myPictBox1
arr[1] = myPictBox2
//etc
arr[1].BackgroundColor = newColor;
And refer to them by index. 并按索引引用它们。
