推荐答案

ListView可能不是您要使用的-确实不是为那种事情设置的，除非您将每行显示为单独的字符串-根据您的描述，我认为这不是您要实现的目标.但是...

A ListView is probably not what you want to use - it really isn''t setup for that kind of thing, unless you display each line as a separate string - I don''t think from your description that that is what you are trying to achieve. But...

string rawData = @"setting1:true;setting2:false;setting3:true;";

或:

Or:

string rawData = File.ReadAllText(@"D:\Temp\Settings.txt");

然后:

Then:

string[] pairs = rawData.Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries);
foreach (string pair in pairs)
    {
    listView1.Items.Add(pair);
    }

会做到的-

但是，使用更具结构化"的控件(例如DataGridView)可能会更好:

Will do it - sort of.

But you might be better off using a "more structured" control, such as a DataGridView:

string rawData = @"setting1:true;setting2:false;setting3:true;";
string[] pairs = rawData.Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries);
List<KeyValuePair<string, string>> list = new List<KeyValuePair<string, string>>();
foreach (string pair in pairs)
    {
    string[] kv = pair.Split(':');
    list.Add(new KeyValuePair<string, string>(kv[0], kv[1]));
    }
dataGridView1.DataSource = list;
