How to convert string to Keys

try to implement combination of keypressing for my programm currently can detect required keypressed (in this post described how) but only predefined in code, but I want to store setting in condig file then read it and use if pressed.

Now can store it, and read as string - currently try to convert readed string to Keys, using next code:

Storing in config file:

<add key="open" value="ControlKey,N"
<add key="close" value="ControlKey,Q" />
<add key="clear" value="ControlKey,D" />
<add key="settings" value="ControlKey,S" />
<add key="colorKey" value="ControlKey,K" />
<add key="fontKey" value="ShiftKey,T" />
<add key="defaultKey" value="ControlKey,P" />

and using it

    private void textBox1_KeyDown(object sender, KeyEventArgs e)
    {
        TypeConverter converter = TypeDescriptor.GetConverter(typeof(Keys));
        string[] keyValueTemp;

        keyValueTemp = cm.GetValueString("open").ToString().Split(',');
        string key1 = keyValueTemp[0];
        string key2 = keyValueTemp[1];

        Keys keys1 = (Keys)converter.ConvertFromString(key1);
        Keys keys2 = (Keys)converter.ConvertFromString(key2);

        if (ModifierKeys == keys1 && e.KeyCode == keys2)
        {
            string keyPressed = e.KeyCode.ToString();
            MessageBox.Show(keyPressed);
        }
    }

But, has next result -

enter image description here So - as you see - this convert control Key to Shiftkey, also try to use code if (ModifierKeys.ToString() == keyValueTemp[0] && e.KeyCode.ToString() == keyValueTemp[1]), but it's not work too.

if use this code

        if (e.Modifiers == Keys.Control && e.KeyCode == Keys.N)
        {
            string keyPressed = e.KeyCode.ToString();
            MessageBox.Show(keyPressed);
        }

all works

Q: how can i convert string to Keys and compare it with keyPressed events?

EDIT

So found my mistake

Keys key = (Keys)converter.ConvertFromString(keyValueTemp[0]);
Keys key2 = (Keys)converter.ConvertFromString(keyValueTemp[1]);
if (e.Modifiers == key && e.KeyCode == key2)
   {
       MessageBox.Show(e.KeyCode.ToString());
   }

forget to add e - from event handler

another way - as written by AccessDenied

 Keys key = (Keys)Enum.Parse(typeof(Keys), keyValueTemp[0], true);

Keys key;
Enum.TryParse("Enter", out key);
