尝试从csv文件读取一些数据c＃

Question

Im trying to read some data from a csv file and display it in c# this works fine but i have 2 different rows in my csv file which i'll be adding too.

I want them to be accessible if say someonet types '1' into the ukNumber field it will pull all of their data.

atm no matter what i type it always displays the last line in my csv file.

namespace Appraisal
{


public partial class Form1 : Form
{

    public Form1()
    {
        InitializeComponent();
    }
    private void ukNumber_TextChanged(object sender, EventArgs e)
    {

    }

    public void search_Click(object sender, EventArgs e)
    {
        using (var reader = new StreamReader(File.OpenRead("C:\\Users\\hughesa3\\Desktop\\details.csv"),
                                 Encoding.GetEncoding("iso-8859-1")))
        {
            while (!reader.EndOfStream)
            {
                var line = reader.ReadLine();
                var values = line.Split(',');

                string idStr = values[0];
                string firstnameStr = values[0];
                string surnameStr = values[0];
                string jobroleStr = values[0];
                string salaryStr = values[0];

                richTextBox1.Text = "Name: " + values[1] + "\nSurname: " + values[2] + "\nJob Role: " + values[3] + "\nSalary: £" + values[4];
            }
        }
    }

    private void richTextBox1_TextChanged(object sender, EventArgs e)
    {

    }

    private void apprasialCode_TextChanged(object sender, EventArgs e)
    {
    }

    private void apprasialBtn_Click(object sender, EventArgs e)
    {
    }

    private void ukNumberLabel_Click(object sender, EventArgs e)
    {

    }
}

}

Answer 2

to read data from csv file:

using (var reader = new StreamReader(File.OpenRead("c:/yourfile.csv"), 
                                     Encoding.GetEncoding("iso-8859-1"))) 
{
    while (!reader.EndOfStream)
    {
        var line = reader.ReadLine();
        var values = line.Split(';'); // replace ';' by the your separator

        string idStr = values[0];
        string firstnameStr = values[0];
        string surnameStr = values[0];
        string jobroleStr = values[0];
        string salaryStr = values[0];

        //convert string
    }
}
