Instructions with a counter

Serban Gabriel

I am sorry for the confusing subject name.
I am newbie to C# programming so i need a little help. Sorry for my english.

Introduction:
I have 6 columnHeader named columnHeader_p1s, p2s, p3s, p4s, p5s, p6s.
All the above columnHeaders are initiated with the .Text = "default")

I have 4 textBox named textBox_p1, p2, p3, p4.
(textBox_p1.Text = "player 1"
textBox_p2.Text = "player2")
textBox_p3.Text = "player3")
textBox_p4.Text = "player4")

The problem:
n = 4;
for ( i = 1; i <= n; i++ )
{
this.columnHeader_p{i}s.Text = textBox_p{i}.Text;
}

I want to achieve the result with a similar command to the above one. (i know the above one is not correct)
I hope you understand what i want :D.

Is it possible?

The result:
columnHeader_p1s.Text = player1;
columnHeader_p2s.Text = player2;
columnHeader_p3s.Text = player3;
columnHeader_p4s.Text = player4;
columnHeader_p5s.Text = default;
columnHeader_p6s.Text = default;

"Case" is out of discussion.

I'm assuming this is a Windows Forms application.

If your labels have been placed directly on the form (and not in some other container such as a panel or groupbox), then you can use code such as the following:

for(int i = 1; i < 1000; i++)
{
Label lbl = (Label)this.Controls["label" + i.ToString()];
lbl.Text = i.ToString();
}

I'm not sure what type of control your columnHeaders are though it doesn't really matter as all controls have a Text property. So the analogous code you'd need for your original problem would be along the following lines:

for(int i = 1; i < 5; i++)
{
   Control ch = this.Controls["columnHeader_p" + i.ToString() + "s"];
   TextBox tb = (TextBox)this.Controls["textBox_p" + i.ToString();
   ch.Text = tb.Text;
}

Thank you so much! I'll test it in a few hours when i get home and tell you if my problem is solved.

Yes, you can create your labels dynamically in the 'for' statement. The code will be something like this:

for(int i = 1; i < 1000; i++)
{
Label lbl = new Label();
lbl.Name = "label" + i.ToString();
// set other properties such as position etc
lbl.Text = i.ToString();
this.Controls.Add(lbl); // make label visible
}

Incidentally, I've edited my previous post to incorporate suggested code for your original problem.

for(int i = 1; i < 1000; i++)
{
Label lbl = (Label)this.Controls["label" + i.ToString()];
lbl.Text = i.ToString();
}

Can I declare labels also in the FOR above? The labels are not declared initially, so I would like to have n labels. [maybe by creating a function that has as parameter create_labels(int n)?]

Thank you so much for the solution above.

I am using this inside of a Button_click() [constructer i guess].

I'm trying to find a way to search (identify) an instruction [by using a number inside of it]... maybe the next example will clear up:

How can i achieve this?:

label1.Text = 1;
label2.Text = 2;
.
.
.
label999.Text = 999;

Can I do such a thing by using a counter i? (with a FOR maybe?)

Thank you for your attention.

columnHeader? Where you using this. FindControl() method is used to find a control from page. You need to provide more information.
