求一正则
分割 数字和字母

例如 123adc 分割后成123 abc
123.123abc ---->123.123 abc
[解决办法]

            string str = "123.123adc";
            foreach (Match match in Regex.Matches(str, @"[0-9]+(\.[0-9]+)?
[解决办法]
[a-zA-Z]+"))
                Console.WriteLine(match.Value);

[解决办法]
string[] result=Regex.Split(str,@"(?<=\d)(?=[a-zA-Z])");
[解决办法]
update:

string[] result=Regex.Split(str,@"(?<=\d)(?=[a-zA-Z])
[解决办法]
(?<=[a-zA-Z])(?=\d)");


[解决办法]

List<string> list = new List<string>() { 
                    "123abc",
                    "123.123abc"
                };
                list = list.Select(a => {
                    Match m =  Regex.Match(a,@"(?i)(\d+?(\.\d+)?)([a-z]+)");
                    return m.Groups[1].Value + " " + m.Groups[3].Value;
                }).ToList();
