ListView列

Question

I have 2 columns in a ListView . My "C:\\file.txt" looks like this:

1;aaa 
2;bbb
3;ccc 
4;ddd 

and so on. (each number and text in separate line) My code:

FileStream spis = File.Open("C:\\file.txt", FileMode.Open, FileAccess.Read);
StreamReader yaRead = new StreamReader(spis);
string yaView = yaRead.ReadToEnd();
yaRead.Close();
spis.Close();
String[] yaArray = yaView.Split(new char[] {';'});
foreach (string ya in yaArray)
{
    listView1.Items.Add(ya);
}

It results

1
aaa
bbb
(...)

...in first column and nothing in second column. Please help me fix it.

Answer 1

You add columns to a list view via the SubItems property of a ListViewItem .

The simplest way is to do something like:

ListViewItem newItem = new ListViewItem("1");
newItem.SubItems.Add("aaa");
listView1.Items.Add(newItem);

If we take your example, we can simply do something like the following:

string[] yaArray = yaView.Split(new string[] { Environment.NewLine }, StringSplitOptions.None); 

This will give you an array that looks like:

[1;aaa]
[2;bbb]
[3;ccc]
[4;ddd]

We've split based on the new line rather than the semi-colon.

Then it's simply a matter of doing the following:

foreach(string lineItem in yaArray)
{
  string[] listViewRow = lineItem.Split(new string[] { ";" }, StringSplitOptions.None); //Now we split on the semi colon to give us each item
  ListViewItem newItem = new ListViewItem(listViewRow[0]);
  newItem.SubItems.Add(listViewRow[1];
  listView1.Items.Add(newItem);
}

That should give you what you want.

Answer 2

Please, add SUBitems to list

foreach(var line in File.ReadAllLines(@"C:\file.txt"))
{
  listView1.Items.Add(line.Split(';'));
}
