I have two functions GetKey and SetKey and i added after this two functions another two functions GetListKey and SetListKey both type of List string.<br/>
<br/>
Now after that i want to add another two functions of Lists type of int GetListIntKey and SetListIntKey but i have a problem since GetKey and SetKey are type of string.
<br/>
<br/>
<br/>
Then what i need to do is when im getting the list in the SetListIntKey i want it to be written in my Options_DB file formmated to string like this:<br/>
<br/>
122,231 233,244 and so on what the list im getting is coordinates of points.<br/>
So i want to write it formatted string to the options_db file and with the GetKey to read the formatted string back so i will have a list with the coordinates when read it back.<br/>
<br/>
<br/>
This is the Options File code:<br/>

In the Options_Db i should see the formmated list int.<br/>
So if in my program in runtime code i will make SetListIntKey(Points) i will see the list of Points coordinates formmated the key to the left and the formmated coordinates on the right like:<br/>
<br/>
Points_Key = 122,233 44,122 121,33 and so on.<br/>
And when i make GetListIntKey in the runtime code so for example:<br/>
<br/>
List<int> test = GetListIntKey()<br/>
So in the test List i will see in index 0 122,233 and ini ndex 1 44,122<br/>
In fact i have two Lists for the points coordinates Point_X and Point_Y so maybe in the SetListIntKey i need to use two Lists and combine them ?<br/>
