通过其字符串名称C＃访问变量的值

Question

I want to store a series (six to be precise) of Windows Forms labels in an array. There are six labels, which follow the naming convention orderLabel0 , orderLabel1 ... orderLabel5 .

I would like to store the pointers to the orderLabels in an array:

Label[] orderLabels = new Label[6];
for(int index = 0; index < 6; index++)
{                
    orderLabels[index] = orderLabel + [index]; //Error!
}

The code somehow needs to treat the string as variable name and store them as "labels" rather than string in the orderLabels array. In other words, when orderLabels[0] is accessed, I am actually accessing orderLabel0 .

Research here and there have led me to dynamic , Reflection and Dictionary options. However, they all require me to specify the object names (correct me if I am wrong), and I am trying to follow the "Do Not Repeat" yourself rule by not having to specify the object six times.

Please advise, thank you.

You can use the Controls form variable to look up the control by name:

Label[] orderLabels = new Label[6];
for(int index = 0; index < 6; index++)
{                
    orderLabels[index] = Controls[string.Format("orderLabel{0}", index)] as Label;
}
