检查字符串列表中包含的字符串

Question

What is the best way to check if a string (of ints) is within a list of string?

Eg Check whether '1' is in (1,2,9,10,11,15)

I had something like:

  if(listofString.Contains(radiolist.SelectedValue))

where the radiolist.SelectedValue is an integer stored in string form.

I don't think the above would work because the '1' would probably match '11' in the string.

Any ideas?

Thanks!

Answer 1

You can split the array by the ',' character and then using .Contains() .

string listofString = "1,2,9,10,11,15";
string[] stringInts = listofString.Split(',');

if (stringInts.Contains(radiolist.SelectedValue.ToString()))
{
    // ...
}

假设listOfString =“1,2,9,10,11,15”

if( listOfString.Split( new char[]{','} ).Any( ss => ss == radioList.SelectedValue ) )
