如何在c#中生成字母数字序列号

using System;
using System.Text;

public string GenerateSerialNumber(int length)
{
    const string chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
    StringBuilder sb = new StringBuilder();
    Random random = new Random();

    for (int i = 0; i < length; i++)
    {
        int index = random.Next(chars.Length);
        sb.Append(chars[index]);
    }

    return sb.ToString();
}

int length = 10; // 设置序列号长度为10
string serialNumber = GenerateSerialNumber(length);
Console.WriteLine("生成的字母数字序列号为：" + serialNumber);
