将排行榜从最高到最低排序
Sorting a leaderboard from highest to lowest
我正在尝试获取 richTextBox
中从最高到最低排序的测验分数。我将玩家姓名、测验和分数保存在名为 scoresClass
的 class 中。在测验结束时,我将 class 呼叫给三个 richTextBox
,以显示他们的姓名、测验和分数。然后我将它们添加到列表并将列表写入文件。排行榜是 richTextBox
,设置为等于文件中的数据。
这是我的代码:
public frmFinal()
{
InitializeComponent();
}
private void frmFinal_FormClosed(object sender, FormClosedEventArgs e)
{
Application.Exit();
}
List<string> scores = new List<string>();
private void frmFinal_Load(object sender, EventArgs e)
{
//sets the leaderboard equal to the file scoreInfo
rchBxScores.Text = File.ReadAllText(".\scoreInfo.bin");
//sets a textbox equal to the players score
rchBxScore.Text = Convert.ToString(scoresClass.score);
rchBxNameScore.Text = scoresClass.name;
rchBxQuizNameScore.Text = scoresClass.quiz;
}
private void btnClearScores_Click(object sender, EventArgs e)
{
//opens the file scoreInfo
FileStream fileStream = File.Open(".\scoreInfo.bin", FileMode.Open);
//empties the file
fileStream.SetLength(0);
//closes the file
fileStream.Close();
//sets the leaderbaord equal to the file
rchBxScores.Text = File.ReadAllText(".\scoreInfo.bin");
scores.Clear();
}
//creates a bool variable and sets it equal to false
bool saved = false;
private void btnSaveScore_Click(object sender, EventArgs e)
{
//checks if saved equals false
if (saved == false)
{
//if saved equals false, it opens the file scoreInfo
using (StreamWriter scoreInfo = new StreamWriter(".\scoreInfo.bin", true))
{
scores.Add(scoresClass.name + "\t" + scoresClass.quiz + "\t" + scoresClass.score);
foreach(string score in scores)
{
scoreInfo.WriteLine(score);
}
}
//clears all the players score details
rchBxNameScore.Clear();
rchBxQuizNameScore.Clear();
rchBxScore.Clear();
rchBxScores.Text = File.ReadAllText(".\scoreInfo.bin");
//sets saved to true
saved = true;
}
}
目前分数是按输入时间计算的,而不是按分数计算的。我不确定我会如何订购它们。
这里是 class:
public class scoresClass
{
public static int score = 0;
public static string name = "";
public static string quiz = "";
public scoresClass(string userName, int userScore, string userQuiz)
{
name = userName;
score = userScore;
quiz = userQuiz;
}
}
由于您使用 StreamWriter
附加到文件,我会将文件作为 scoreClass
的集合读回,而不是盲目读取文件并将其转储到 richTextBox
。沿着这些路线。
我也必须更改您的 class 定义。
public class scoresClass
{
public int score = 0;
public string name = "";
public string quiz = "";
public scoresClass(string userName, string userQuiz, int userScore)
{
name = userName;
score = userScore;
quiz = userQuiz;
}
}
private List<scoresClass> importScoresFromFile(string path)
{
var listOfScores = new List<scoresClass>();
var rawScores = File.ReadAllLines(path);
foreach (var score in rawScores)
{
string[] info = score.Split('\t');
listOfScores.Add(new scoresClass(info[0], info[1], Convert.ToInt32(info[2])));
}
return listOfScores.OrderByDescending(r => r.score).ToList();
}
一旦您将所有分数记入内存,您就可以做一些 LINQ
工作来对它们进行排序。然后,您可以遍历 List<scoresClass>
中的每个值并根据需要导出到 richTextBox
。
