vb.net要怎么retrieve combo box SelectedItem的一部分的data呢？

vb.net要怎么retrieve combo box SelectedItem的一部分的data呢？

比如说我的combobox里的collections有
formula one
formula two
formula three

假设我选第一个item ---> formula one 然后display在一个label
code:
    label.Text=combobox.SelectedItem.Text

label就会display "formula one"

如果我只要在选了item后只display "formula" 而已要怎么写呢？

请各位前辈帮帮忙，谢谢

Sorry for using english.
You can use substring to get the only text you want
example:
dim str1 as string
str1 = label1.text  'label1.text which hold the string variable
str1 = str1.substring(0,6) 'U will get 7 character
label1.text = str1  'Assign it to label1.text
