C# string into object like conversion?

[-Kobas-]

Is it possible in C# to use textmacros like in vjass code?

For example, I want to send an integer into function.
And then that function use this argument in object names within it.

some_function(string text)
{
     $text$.Text = "something like this";
     variable_$text$ = 1; // + this
     variable[$text$] = whatever; // and/or even something like this...
}

EDIT:

I need to solve next problem:

func(Button b1, Button b2, Label l1, Label l2)
{
     b1.Text = "some text 1";
     b1.Text = "some text 1";
     l1.Text = "some text 2";
     l2.Text = "some text 2";
     //...
}

//some code
//...
func(button_x_1, button_y_1, label_x_1, label_y_1);
func(button_x_2, button_y_2, label_x_2, label_y_2);
func(button_x_3, button_y_3, label_x_3, label_y_3);
//...


//==================================================
func( ID )
{
     button_x_$ID$.Text = "some text 1";
     button_y_$ID$.Text = "some text 1";
     label_x_$ID$.Text = "some text 2";
     label_y_$ID$.Text = "some text 2";
     //...
}

func(1);
func(2);
func(3);

Original code is like 20 times larger that this here.
Everything is working fine, I just need to know is they any way around.

Because all I need is to send this simple integer (call it ID) that will then edit all those objects:
button_x_$ID$
button_y_$ID$
label_x_$ID$
label_y_$ID$

Only way I see here, as some sort of solution, is to make array:
B_X[1] = button_x_1;
B_X[2] = button_x_2;
B_X[3] = button_x_3;
B_Y[1] = button_y_1;
B_Y[2] = button_y_2;
B_Y[3] = button_y_3;
etc

But that create other problems like static and non static class members, I need to create huge lists of those array initialization and so on.

Why don't you put all your buttons into a list? You can do this manually or you can use reflection.

I think it is because it is bad programming practice. You should either use inheritance or procedure calls (static methods) to prevent procedural coupling in the code while keeping type safety and readability.

How about something like:

this.Controls.Find("button_x_"+ID, true);

Should work on WinForms, and when it comes to Silverlight and Windows Phone, you can just use MVVM instead by binding the text to an element. Or use VisualTreeHelper/custom recursive function to get the needed control.

public Control GetButton(string prefix ,int i)
        {
            foreach (Control C in this.Controls)
            {
                if (C.Name == prefix + Convert.ToString(i))
                {
                    return C;
                }
            }

            return null;
        }

Something along those lines?

Thank you guys, exactly what I needed.

@Crazed_seal2: better use this.Controls.Find("button_x_"+ID, true); - it's an inbuilt function, which most likely means the CL code is more optimized.

Also it won't work with Windows Phone or Silverlight, those need alternative solutions.

That find function returns an array. You're going to have to loop through it, or check if the array has more than one item.

Exactly, it's much easier to do it the way @Crazed_seal2 shown. Dunno how I didn't think of that earlier...

public Control GetButton(string prefix ,int i, string sufix)
{
     foreach (Control c in this.Controls)
     {
          if (c.Name == prefix + Convert.ToString(i) + sufix)
          {
               return c;
          }
     }
     return null;
}

//...

    //... so something like...
    Button b = GetButton("whatever", 1, "") as Button;
    //...

Like I said in the chat, use a map. Maps were meant for exactly this usage.

Dictionary<string, Control> controlDict = new Dictionary<string, Control>();

foreach (Control c in this.Controls)
{
    controlDict.Add(c.Name, c);
}

...

Control something = controlDict["something"];

var control = this.Controls.Find("button_x_"+ID, true)[0];

still seems more legit to me, and probably faster ^^ In case you properly get the exact name it should work out just fine.

Actually, this is brilliant, lol.

They told me (both my programmer dad and my CS teacher) that one of the most important features of a programmer is lazyness - don't program something that's already there to use, in the worst case try to find a shortcut Can't say it's always true, but most often it is
