Answer 1

not using regex cos I dont really like them - story goes "you have a problem, you decide to use regex on it, you now have 2 problems"

 char[] digits = {'0','1','2','3','4','5','6','7','8','9'};
 string s = "ABCD EFG 201 E";
 var idx = s.IndexOfAny(digits);
 if (idx !=-1){
     var first = s.Substring(0,idx);
     var second = s.Substring(idx);
 }

Using Regex , you can do it like below:

    string Text = "ABCD EFG 201 E";  
    string[] digits = Regex.Split(Text, @"(\d.*)");  
    foreach (string value in digits)  
        Console.WriteLine(value);
