读取行并将其从外部文本文件 c# 中添加到列表中

Question

从外部文本文件读取和解析每个部件行并将其添加到部件列表中的最佳方法是什么。 这是下面的代码。

   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 });

这是我正在尝试做的，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= ""});

       }
  }

简单的文本文件示例

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)
            });
        }
