讀取行並將其從外部文本文件 c# 中添加到列表中

Question

從外部文本文件讀取和解析每個部件行並將其添加到部件列表中的最佳方法是什么。 這是下面的代碼。

   List<Part> parts = new List<Part>();

    // Add parts to the list.
    parts.Add(new Part() {PartName = "crank arm", PartId = 1234});
    parts.Add(new Part() { PartName = "chain ring", PartId = 1334 });
    parts.Add(new Part() { PartName = "regular seat", PartId = 1434 });
    parts.Add(new Part() { PartName = "banana seat", PartId = 1444 });
    parts.Add(new Part() { PartName = "cassette", PartId = 1534 });
    parts.Add(new Part() { PartName = "shift lever", PartId = 1634 });

這是我正在嘗試做的，但它不起作用。

  {
    var fileStream = new FileStream(@"~App_Data/file.text", FileMode.Open, FileAccess.Read);
    using (var streamReader = new StreamReader(fileStream, Encoding.UTF8))
      {
       string line;
       while ((line = streamReader.ReadLine()) != null) {

           parts.Add(new Part() { PartName = "", PartId= ""});

       }
  }

簡單的文本文件示例

new Part() {PartName = "crank arm", PartId = 1234};
new Part() { PartName = "chain ring", PartId = 1334 };
new Part() { PartName = "regular seat", PartId = 1434 };
new Part() { PartName = "banana seat", PartId = 1444 };

Answer 1

string lines = System.IO.File.ReadAllLines(MapPath(@"~/App_Data/file.text");
for(int i=0; i<lines.Lemgth; i++)
{
     Match m = Regex.Match(lines[i],"\{\s*PartName\s*=\s*\"([^\"]*)"\s*,\s*PartId\s*=\s*(\d+)\s*\}");
    if(m.Success) parts.Add(new Part(){PartName = m.Groups[1].Value, PartId = int.Parse(m.Groups[2].Value)});
}

Answer 2

        //references
        using System.IO;
        using System.Text.RegularExpressions;


        //code that goes in the method
        List<Part> parts = new List<Part>();
        foreach (string line in File.ReadAllLines(@"~App_Data/file.text"))
        {
            parts.Add(new Part()
            {
                PartName = line.Split('"')[1],
                PartId = Convert.ToInt32(Regex.Match(line, @"\d+").Value)
            });
        }
