将单元格位置字符串解析为行和列

Question

我有string col= "AB21"一个excel细胞的位置.

我想将其解析为string column = "AB"&int row = 21;

我怎样才能做到这一点？

Answer 1

string col = "AB21";
int startIndex = col.IndexOfAny("0123456789".ToCharArray());
string column = col.Substring(0, startIndex);
int row = Int32.Parse(col.Substring(startIndex));

当然,您应该保证输入字符串的格式正确.

Answer 2

您有一个选项是使用正则表达式来验证和解析输入字符串.请参阅下面的代码.

using System;
using System.Text.RegularExpressions;

namespace DemoRegExForStackOverflow
{
    class Program
    {
        static void Main(string[] args)
        {
            var regex = new Regex(@"(?<col>([A-Z]|[a-z])+)(?<row>(\d)+)");
            var input = @"AB12";
            var match = regex.Match(input);

            if( match != null )
            {
                var col = match.Groups["col"];
                var row = match.Groups["row"];

                Console.WriteLine("Input is: {0}", input);
                Console.WriteLine("Column is {0}", col.Value);
                Console.WriteLine("Row is {0}", row.Value);
             }
             else
             {
                 throw new ArgumentException("Invalid input");
             }
        }
    }
}
