我可能不会写这个（我是C＃lol的新手），但我需要C＃白名单/激活/许可证的帮助。
因此，如果我在文本框中将1111-1111-1111-1111作为许可证密钥编写，我将31-12-9999作为到期日而不是Discord#5550作为用户名，这是有意的，但不适用于多行。
我需要到期日期和用户名以及密钥旁边的用户名，我正在尝试拆分字符串，但它只适用于一次一行，所以即使我使用2222-2222-2222-2222作为键，它仍然会得到不是Discord#5550作为用户名，不应该发生，应该是charlootus#3330.
我已经离开了代码供你们查看并修复。
白名单（也作为pastebin，代码查看）：
1111-1111-1111-1111|31-12-9999|Not Discord#5550
2222-2222-2222-2222|31-12-9999|charlootus#3330
程序不知道到期日或用户名，它从从Pastebin下载的字符串中获取，并使用输入的密钥搜索相邻的用户名和到期日期，然后验证。第二个关键是从第一行拉出到期和用户名，这不应该发生。
应该是一个简单的解决方案，但我环顾四周，似乎找不到任何东西。

这可能是另一种方法，但错误似乎是你为每一条新线获得的\r\n。
我写了几行来摆脱这个错误并且工作得很好，请阅读评论并询问是否有任何不清楚的地方！

您的白名单包含两行文字。因此，您的第一步应该是按新行拆分
string listOfUsers = whitelist.Split('\n');
您可以将其余代码放入foreach或循环中，如下所示：
foreach(var user in ListOfUsers) // thanks to it you will check all users, not only the first one
{
string[] result = user.Split('|');
string whitelistx = result[0];
string expiry = result[1];
string username = result[2];
if (user.Contains(fin))
{
// rest of your code
当然，您可以优化此代码，但这只是为了回答有关仅检查第一个用户的问题。
问题是你一次搜索所有行。您需要拆分换行符并分别搜索每一行。
string data = new System.Net.WebClient() { Proxy = null }.DownloadString("https://pastebin.com/raw/ai8q5GEA");
// Split on line breaks
var lines = data.Split(new[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);
// Search for license key (might want to change this)
var foundLicense = lines.FirstOrDefault(l => l.StartsWith(fin));
if (foundLicense != null)
{
var values = foundLicense.Split('|');
var whitelist = values[0];
var date = DateTime.ParseExact(values[1], "dd-MM-yyyy", System.Globalization.CultureInfo.InvariantCulture);
var username = values[2];
/* ... */
}
我个人会创建一个类（DTO）来解析文本时保存信息。
void Main()
{
string fin = "111";
string data = new System.Net.WebClient() { Proxy = null }.DownloadString("https://pastebin.com/raw/ai8q5GEA");
// Parse data to DTO-objects
var licenseData = data.Split(new[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries)
.Select(l => l.Split('|'))
.Select(x => new LicenseModel
{
LicenseKey = x[0],
Date = DateTime.ParseExact(x[1], "dd-MM-yyyy", System.Globalization.CultureInfo.InvariantCulture),
Username = x[2]
})
.ToList();
// Find matching license
var foundLicense = licenseData.FirstOrDefault(l => l.LicenseKey.StartsWith(fin));
if (foundLicense != null)
{
/* FOUND LICENSE */
}
}
public class LicenseModel
{
public string LicenseKey { get; set; }
public DateTime Date { get; set; }
public string Username { get; set; }
}
