Question

我的代码仅适用于左侧的第一组，而不适用于右侧的另一组，它给我一个错误：“给定的密钥不在字典中”

使用MAJOR_PSIST开始第二组的正确代码是什么？

这是我的代码：

        var data = File
        .ReadAllLines(textfiletest)
        .Select(x => x.Split(':'))
        .Where(x => x.Length > 1)
        .GroupBy(x => x[0].Trim())
        .ToDictionary(x => x.Key, x => x.First()[1]);

这是我的文本文件{textfiletest}

   MINOR_PSIST                    : 2          MAJOR_PSIST                    : 8        
   CRITICAL_PSIST                 : 60         ECSFB_CALL_CONTROL_TYPE        : AUTOMATIC
   CALL_CONTROL_TYPE              : AUTOMATIC  REGI_CONTROL_TYPE              : AUTOMATIC
   PAGE_CONTROL_TYPE              : AUTOMATIC  THRESHOLD_TIME                 : 1        
   ECSFB_PER_UNIT_SEC_IN_NORMAL   : 0          CALL_PER_UNIT_SEC_IN_NORMAL    : 0        
   REGI_PER_UNIT_SEC_IN_NORMAL    : 0          PAGE_PER_UNIT_SEC_IN_NORMAL    : 1800     
   ECSFB_PER_UNIT_SEC_IN_MINOR    : 25         CALL_PER_UNIT_SEC_IN_MINOR     : 25

Answer 1

我相信你想按组密钥对第二列进行分组。看看下面给出的代码是否有效。

var data = File
    .ReadAllLines(textfiletest)
    .Select(x => x.Split(':'))
    .Where(x => x.Length > 1)
    .GroupBy(x => x[0].Trim())
    .ToDictionary(x => x.Key, x => x[1]);

Answer 2

我从this帖子修改了@ Strilanc（感谢:) :)扩展功能：

public function store(InterestRequest $interest)
{
    $interest = new Follower(array(
        'user_id' => $interest->get('interest_id'),
        'follower_id'  => Auth::id()
    ));

    $interest->save();
}

这是代码：

    public static class Extensions
    {
        public static IEnumerable<T[]> Partition<T>(this IEnumerable<T> sequence, int partitionSize)
        {
            var buffer = new T[partitionSize];
            var n = 0;
            foreach (var item in sequence)
            {
                buffer[n] = item;
                n += 1;
                if (n == partitionSize)
                {
                    yield return buffer;
                    buffer = new T[partitionSize];
                    n = 0;
                }
            }
            //partial leftovers
            if (n > 0) yield return buffer;
        }
    }

Answer 3

问题是您必须先将每个组从每行分开，然后才能创建Dictionary。看起来第一组的长度为42个字符，因此我们可以使用String.Substring()将每个组分开。

每个群组拆分后，您可以使用Dictionary

建立Linq

using System;
using System.Collections.Generic;
using System.Linq;

public class Program
{
    public static void Main()
    {
        List<string> fileLines = new List<string>
        {
            "MINOR_PSIST                    : 2          MAJOR_PSIST                    : 8        ",
            "CRITICAL_PSIST                 : 60         ECSFB_CALL_CONTROL_TYPE        : AUTOMATIC",
            "CALL_CONTROL_TYPE              : AUTOMATIC  REGI_CONTROL_TYPE              : AUTOMATIC",
            "PAGE_CONTROL_TYPE              : AUTOMATIC  THRESHOLD_TIME                 : 1        ",
            "ECSFB_PER_UNIT_SEC_IN_NORMAL   : 0          CALL_PER_UNIT_SEC_IN_NORMAL    : 0        ",
            "REGI_PER_UNIT_SEC_IN_NORMAL    : 0          PAGE_PER_UNIT_SEC_IN_NORMAL    : 1800     ",
            "ECSFB_PER_UNIT_SEC_IN_MINOR    : 25         CALL_PER_UNIT_SEC_IN_MINOR     : 25       ",
            "REGI_PER_UNIT_SEC_IN_MINOR     : 50         PAGE_PER_UNIT_SEC_IN_MINOR     : 25       ",
            "ECSFB_PER_UNIT_SEC_IN_MAJOR    : 20         CALL_PER_UNIT_SEC_IN_MAJOR     : 20       ",
            "REGI_PER_UNIT_SEC_IN_MAJOR     : 40         PAGE_PER_UNIT_SEC_IN_MAJOR     : 5        ",
            "ECSFB_PER_UNIT_SEC_IN_CRITICAL : 15         CALL_PER_UNIT_SEC_IN_CRITICAL  : 15       ",
            "REGI_PER_UNIT_SEC_IN_CRITICAL  : 30         PAGE_PER_UNIT_SEC_IN_CRITICAL  : 1        ",
            "UNIT_SECOND_INTERVAL           : 3          ",
            "RESULT = OK",
            "COMPLETED  "
        };

        // Each group contains a colon
        var groupLines = fileLines.Where(line => line.Contains(":"));

        // Break out each group to its own line
        List<string> groups = new List<string>();
        foreach (string line in groupLines)
        {
            groups.Add(line.Substring(0, 42));
            if (line.Length > 44)
            {
                groups.Add(line.Substring(44));
            }
        }

        // Build the dictionary from the groups
        Dictionary<string, string> dictionary = groups.Select(line => line.Split(':'))
            .GroupBy(pieces => pieces[0].Trim(), pieces => pieces[1].Trim())
            .ToDictionary(kvp => kvp.Key, kvp => kvp.First());

        // Print the dictionary to verify success
        foreach (var r in dictionary)
        {
            Console.WriteLine("Key: {0,-35} Value: {1}", r.Key, r.Value);
        }
    }
}
