c# - 如何分离String数组数据？

Question

我有字符串数组:

String[] values  = {"A1","B1","C1","5"};

我需要像这样分隔数字和单元格引用:

String[] b = {"A1","B1","C1"}; 
String[] c = {"5"}; 

Answer 1

使用 linq 非常简单(除了“仅数字字符串识别”)。这是:

static void Main(string[] args)
{

    // Input:
    String[] values = { "A1", "B1", "C1", "5" };

    // Results:
    String[] digits = (from x in values where StringContainsNumbersOnly(x) select x).ToArray();
    String[] cellRefs = (from x in values where !digits.Contains(x) select x).ToArray();

}

static bool StringContainsNumbersOnly(string inputString)
{
    return System.Text.RegularExpressions.Regex.IsMatch(inputString, @"^\d+$");
}
