How to add another function call control and modify properties of l l

CodePudding user response:

L.N ame="labNum_" + i.T oString ();
In this case the
You can use the

Label=l (form. Controls [" labNum_ digital "] as Label).
L.T ext=XXX;

CodePudding user response:

If it is the individual controls, # 1, if it is full, it can be:

 
This. Controls. OfType (). ToList (). The ForEach (f=& gt; 
{
F.B ackColor=Color. LightCyan;//change the background color in 
});

I can in other functions such as DrawGame () used in labNum_ [I] Text="xx"; Modify its properties?

As long as it is in the same class can, create label is private, reference is less than in the other classes!

O the results don't let me reference?

CodePudding user response:

You wrote, system to judge the current does not exist the labNum_3 this control, error,
You can check for label Controls, find out the type and order for the third, to modify it

I suddenly thought of using generic methods to save control as a generic type but how to output in the form of generic controls,,
Thank god to guide my new one

All the code I am writing to you, but you still use your own code

((Label) enclosing Controls [" lblNum_3] "). The Text="1";

I also to learn, is really more a great god,

CodePudding user response:

The Label Label=container control. Controls [] "(name)" as the Label;
Can do everything

CodePudding user response:

. Try to use the label tag to store a serial number, read the serial number of the label to change content,

 public void AddLabel () 
{
for (int i=0; I & lt; 16. I++) 
{
The Label l=new Label (); 
L.N ame="labNum_" + i.T oString (); 
L.F ont=new Font (" black ", 15); 
L.T ext="2"; 
L.t ag=I; 
L.L ocation=new Point (215 + (I % 4) * 50, 215 + (I/4) * 50); 
L.S considering=new Size (20, 20). 
This. Controls. The Add (l); 
} 
} 
Private bool changeLabText (string num, string TXT) 
{
Foreach (c in this control. Controls) 
{
If (c.t ag==num) 
{
((Label), c). The text=TXT; 
return true; 
} 
} 
return false; 
}
