将.csv文件加载到字典中，我不断收到错误“无法从”string []“转换为”string“ [英] Loading a .csv file into dictionary, I keep getting the error "cannot convert from 'string[]' to 'string'"

问题描述

我使用streamreader读取.csv文件，然后我需要分割值并将其放入字典中。到目前为止，我有：

I've used streamreader to read in a .csv file, then i need to split the values and put them into a dictionary. so far i have:

namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
Dictionary<string, string> dict = new Dictionary<string, string>();   
    public Form1()
    {
        InitializeComponent();
    }
    private void Form1_Load(object sender, EventArgs e)
    {
        using (StreamReader reader = new StreamReader("textwords0.csv"))
        {
            string line;
            while ((line = reader.ReadLine()) != null)
            {
                string[] parts = line.Split(',');
                dict.Add(parts[0], parts[1]);
            }
        }
    }

我不断收到错误不能从'string []'转换为'string'，但无法解决如何解决它。

I keep getting the error "cannot convert from 'string[]' to 'string'" but cant work out how to fix it.

提前感谢！

更新：
...我不小心把csv文件打开，现在正在工作，抱歉因为浪费时间，他们认为我有一个不同的电子表格打开，一些非常有用的建议，但感谢所有的帮助

update: ...I accidentally left the csv file open and its working now, sorry for wasting time guys thought i had a different spreadsheet open, some very useful advice though thanks for all the help!

推荐答案

如果您使用 .NET 4.0 ，以下是非常简洁的，应该完成同样的事情：

If you're using .NET 4.0, the following is really succinct and should accomplish the same thing:

var dict = File.ReadLines("textwords0.csv").Select(line => line.Split(',')).ToDictionary(line => line[0], line => line[1]);
