保存点数组 [英] save point array

问题描述

如何使用

推荐答案

private static void SavePointArray(string FileName, Point[] PointArray)
{
    StreamWriter writer = File.CreateText(FileName);
    foreach (Point point in PointArray)
        writer.WriteLine(point.ToString());
    writer.Dispose();
}

private static readonly char[] RemoveChars = new char[] { ''{'', ''}'', ''='', ''X'', ''Y'', '','' };

private static Point[] LoadPointArray(string FileName)
{
    StreamReader reader = File.OpenText(FileName);
    List<Point> result = new List<Point>();
    string line;
    string[] chunks;
    int x, y;
    while (!reader.EndOfStream)
    {
        line = reader.ReadLine();
        chunks = line.Split(RemoveChars, StringSplitOptions.RemoveEmptyEntries);
        int.TryParse(chunks[0], out x);
        int.TryParse(chunks[1], out y);
        result.Add(new Point(x, y));
    }
    reader.Dispose();
    return result.ToArray();
}

将点[]保存到文件中以供下一步使用 您还应该进行一些检查，以确保一切正常.

You should also do some checking to make sure everything is ok.

要添加到上一个答案，您可以使用PointConverter对System.Drawing.Point进行序列化和反序列化(也称为解析).班级.这比上一个答案中介绍的方法更干净.例如:

To add to the previous answer, you can serialize and deserialize (aka, parse) a System.Drawing.Point with the PointConverter class. This is cleaner than the method presented in the previous answer. For example:

PointConverter con = new PointConverter();
string str = con.ConvertToString(new Point(30, 40));
Point p = (Point)con.ConvertFromString(str);
MessageBox.Show(p.ToString());

Google的序列化c#"或序列化数组c#"，您会发现很多例子...

Google for ''serialize c#'' or ''serialize array c#'' and you''ll find plenty of examples...
