c# - Form instance members and static member -

i have formdlg can accessed 2 two forms button click on form1, needs instance- can have multiple formdlg

but other place, need single instance of formdlg

any ideas thank u

following example code of class can provide answer you.

class formdlg {     static formdlg instance;     public static formdlg getinstance()     {         if (instance == null)             instance = new formdlg();          return instance;     } } 

since constructor public can call new in form1 multiple instances anytime want.

in form2 use static function getinstance retreive single instance everytime.

hope helps.
