C#将字符串行拆分为多个字符串

标签: c# arrays string list text

我试图弄清楚如何将一些cmd输出分成多个字符串,以后我可以用来设置标签。

我使用的代码是:

ProcessStartInfo diskdrive = new ProcessStartInfo("wmic", " diskdrive get index, model, interfacetype, size");
diskdrive.UseShellExecute = false;
diskdrive.RedirectStandardOutput = true;
diskdrive.CreateNoWindow = true;
var proc = Process.Start(diskdrive);

string s = proc.StandardOutput.ReadToEnd();

它提供如下输出:

Index  InterfaceType  Model                   Size           
2      IDE            WesternDigital    1000202273280  
1      IDE            Seagate             500105249280   
0      IDE            SAMSUNG SSD 830 Series  128034708480

是否可以将它放在列表或数组中,以便我可以获得例如磁盘2的大小,或磁盘0的接口类型。我可以在C#中做一些基本的事情,但这是我的头脑:我

这是一个工作示例。 “结果”将包含一个包含您需要的相关部分的列表。这是第一次通过,我确信可以在某种程度上进行重构:

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

namespace columnmatch
{
    internal class Program
    {

        private const string Ex1 = "2      IDE            WesternDigital    1000202273280";
        private const string Ex2 = "1      IDE            Seagate             500105249280 ";
        private const string Ex3 = "0      IDE            SAMSUNG SSD 830 Series  128034708480";

        private static void Main(string[] args)
        {
            var result = new List<MyModel>();
            result.Add(ParseItem(Ex1));
            result.Add(ParseItem(Ex2));
            result.Add(ParseItem(Ex3));
        }

        private static MyModel ParseItem(string example)
        {
            var columnSplit = example.Split((char[]) null, StringSplitOptions.RemoveEmptyEntries);

            int index = -1;
            string interfaceType = string.Empty;
            long size = -1;
            string model = string.Empty;

            if (columnSplit.Count() == 4)
            {
                //direct match (no spaces in input)
                index = Convert.ToInt32(columnSplit[0]);
                interfaceType = columnSplit[1];
                model = columnSplit[2];
                size = Convert.ToInt64(columnSplit[3]);
            }
            else
            {
                string modelDescription = string.Empty;

                for (int i = 0; i < columnSplit.Count(); i++)
                {
                    if (i == 0)
                    {
                        index = Convert.ToInt32(columnSplit[i]);
                    }
                    else if (i == 1)
                    {
                        interfaceType = columnSplit[i];
                    }
                    else if (i == columnSplit.Count() - 1) //last
                    {
                        size = Convert.ToInt64(columnSplit[i]);
                    }
                    else
                    {
                        //build the model
                        modelDescription += columnSplit[i] + ' ';
                    }
                }

                model = modelDescription.TrimEnd();
            }

            var myItem = BuildResultItem(index, interfaceType, model, size);
            return myItem;
        }

        private static MyModel BuildResultItem(int index, string interfaceType, string model, long size)
        {
            var myItem = new MyModel
            {
                Index = index,
                InterfaceType = interfaceType,
                Model = model,
                Size = size
            };

            return myItem;
        }

        private class MyModel
        {
            public int Index { get; set; }
            public string InterfaceType { get; set; }
            public string Model { get; set; }
            public long Size { get; set; }
        }
    }
}

这个答案遵循我的评论中的事实:总会有4列,第一列和最后一列始终是数字,并从那里开始构建。

答案 1 :(得分:0)

您运行的命令似乎确保每列之间有一个双倍空格。然后就是在双字符串上进行字符串拆分的问题。

所以,鉴于你的字符串s,这对我有用:

var map =
    s
        .Split(Environment.NewLine.ToCharArray(), StringSplitOptions.RemoveEmptyEntries)
        .Skip(1)
        .Select(x => x.Split(new [] { "  " }, StringSplitOptions.RemoveEmptyEntries))
        .Select(x => x.Select(y => y.Trim()).ToArray())
        .ToDictionary(
            x => int.Parse(x[0]),
            x => new
            {
                InterfaceType = x[1],
                Model = x[2],
                Size = ulong.Parse(x[3]),
            });

我可以这样做:

string it = map[0].InterfaceType;
ulong size = map[2].Size;
