将数字转换为C＃中的字母以便在Microsoft Excel中使用[复制]

这是一个也处理两个字母列的版本（在Z列之后）：

static string GetColumnName(int index)
{
    const string letters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

    var value = "";

    if (index >= letters.Length)
        value += letters[index / letters.Length - 1];

    value += letters[index % letters.Length];

    return value;
}

只需将其转换为char并执行“ToString（）” .

using System;
using System.Collections.Generic;

public class MyClass
{
    public static void RunSnippet()
    {
        int myNumber = 65;
        string myLetter = ((char) myNumber).ToString();
        WL(myLetter);
    }

    #region Helper methods

    public static void Main()
    {
        try
        {
            RunSnippet();
        }
        catch (Exception e)
        {
            string error = string.Format("---\nThe following error occurred while executing the snippet:\n{0}\n---", e.ToString());
            Console.WriteLine(error);
        }
        finally
        {
            Console.Write("Press any key to continue...");
            Console.ReadKey();
        }
    }

    private static void WL(object text, params object[] args)
    {
        Console.WriteLine(text.ToString(), args);   
    }

    private static void RL()
    {
        Console.ReadLine(); 
    }

    private static void Break() 
    {
        System.Diagnostics.Debugger.Break();
    }

    #endregion
}
