Question

我正在尝试从文件中读取并使用c＃将其转换为字典。该文件包含

等数据

1 1 1 acsbd 
1 2 1 123ws

这里我想将前六个字符设为键，将剩余字符设为值。

这是我尝试的代码（它主要来自stackoverflow）

System.IO.StreamReader file = new System.IO.StreamReader (
  @"D:\Programming\Projects\Launch pad\itnol\KeySound");


     while ((line = file.ReadLine()) != null)
     {
         char[] line1 = line.ToCharArray();
         if (line1.Length >= 11)
         {
             line1[5] = ':';
             line = line1.ToString();
             //Console.WriteLine(line);
         }
         var items = line.Split(new[] { '(', ')' }, StringSplitOptions.RemoveEmptyEntries)
             .Select(s => s.Split(new[] { ':' }));

         Dictionary<string, string> dict = new Dictionary<string, string>();
         foreach (var item in items)
         {
             Debug.Log(item[0]);
             dict.Add(item[0], item[1]);
         }

它符合但在运行时抛出IndexOutOfRangeException 异常

谢谢。

尝试使用 Linq ：

using System.IO;
using System.Linq;

...

string fileName = @"D:\Programming\Projects\Launch pad\itnol\KeySound";

...

Dictionary<string, string> dict = File 
  .ReadLines(fileName)    
  .Where(line => line.Length >= 11)           // If you want to filter out lines 
  .ToDictionary(line => line.Substring(0, 6), // Key:   first 6 characters
                line => line.Substring(6));   // Value: rest characters

修改：否 Linq ，没有File版本：

string fileName = @"D:\Programming\Projects\Launch pad\itnol\KeySound";

...

Dictionary<string, string> dict = new Dictionary<string, string>();

// Do not forget to wrap IDisposable into using
using (System.IO.StreamReader reader = new System.IO.StreamReader(fileName)) {
  while (true) {
    string line = reader.ReadLine();

    if (null == line)
      break;
    else if (line.Length >= 11) 
      dict.Add(line.Substring(0, 6), line.Substring(6));
  }
}

从文件中获取数据并使用c＃将其转换为字典统一
