How to save Back color in windows form application

[kamalmahdavi]

I wrote this code behind a button

"
colordialog.showdialog();
File.WriteAllText("dlg.txt",this.BackColor.Name);
"
And I wrote this code in Form Load as well
"
this.BackColor = Color.FromName(File.ReadAllText("dlg.txt"));
"

but I got an error and I dont know what is this... Any one knows "Control does not support transparent background colors"

Color bgColor = this.BackGroundColor;

Hi kamalmahdavi,

You can try using RGB color as follows:
on button click

 colordialog.ShowDialog();
File.WriteAllText("dlg.txt", colordialog.Color.ToArgb().ToString());
this.BackColor = Color.FromArgb(colordialog.Color.ToArgb());
 

and on form load

if (File.Exists("dlg.txt"))
{
    int nARGB = 0;
    int.TryParse(File.ReadAllText("dlg.txt"), out nARGB);
    this.BackColor = Color.FromArgb(nARGB); 
}
