从TextFile中读取每一行并将其添加到ListBox C＃

Question

private void button2_Click(object sender, EventArgs e)
{
     string[] lines = System.IO.File.ReadAllLines(this.textBox2.Text);
     foreach (string line in lines)
     {
          this.listProxy.Items.Add(lines);
     }
}

When I click the button it is not writing it out to the ListBox .

How can I make it add each line in order to the ListBox ?

Answer 1

Your should use line instead lines

this.listProxy.Items.Add(line);

look the code edited below:

private void button2_Click(object sender, EventArgs e)
{
    string[] lines = System.IO.File.ReadAllLines(this.textBox2.Text);
    foreach (string line in lines)
    {
        this.listProxy.Items.Add(line);
    }
}

First, for whta i see in the code provided you are getting text from textbox and not from a TextFile.

Second, make sure that the TextFile you are going to use, contains information.

Third, you could use a try catch block in order to detect errors and be able to correct them before sending this to production.
