c# - How do I change the content of a WinForms label from the Program.cs main method? -

so have start-up routine in main method checks make sure there content in .txt file.

 fileinfo finfo = new fileinfo(datadir);  if (finfo.length < 64)  {      //do stuff here if file not long enough  } 

i want able make label on winforms app display text , want grey out controls, can't seem find way reference said label/controls, or object in form matter. beginner, , struggling figure out.

if want able work form object main() method need pass in object instead of using new keyword.

this see (visual studio produces code).

static class program {     static void main()     {         application.enablevisualstyles();         application.setcompatibletextrenderingdefault(false);         application.run(new form1());     } } 

what can work form object.

static class program {     static void main()     {         application.enablevisualstyles();         application.setcompatibletextrenderingdefault(false);         form1 myform = new form1(); //create object here         //you can work form here         application.run(myform); //pass in form     } }
