c# - Separate textbox value and add to list -

hi trying take numbers added textbox , on button click add numbers list, instance user can input:

123456

so become:

1

2

3 etc

i'm not sure how separate each digit , add list?

        list<int> integerlist = new list<int>();          try         {             int number = int.parse(textbox1.text);                             (int = 0; < number; i++)             {                 integerlist.add(number);                 listbox1.items.add(number);             } 

you can use indexer characters of string.

try {               (int = 0; < textbox1.text.length; i++)     {          integerlist.add(int.parse(textbox1.text[i].tostring());          listbox1.items.add(textbox1.text[i]);     }  } 

you can use linq well.

list<int> integerlist = new list<int>(); textbox1.text.select(c=>convert.toint32(c).tostring()).tolist();
