Question

To read i tried this code:

In the top of Form1 i did:

Dictionary<string, List<string>> LocalyKeyWords = new Dictionary<string, List<string>>();

In the constructor i did:

keywords = @"d:\Keywords.txt";
            if (File.Exists(keywords))
            {
                LoadKeys(LocalyKeyWords, keywords);
            }

The function LoadKeys:

private void LoadKeys(Dictionary<string,List<string>> disctionary, string FileName)
        {
            var lines = File.ReadAllLines(keywords).Select(l => l.Split(','));
            var dict = new Dictionary<string, List<string>>();
            foreach(var splits in lines)
            {
                var key = splits.First();
                var value = splits.Skip(1).ToList();
                try {dict.Add(key, value);
                }
                catch(Exception ex)
                {  } } 
        }

No exceptions but in the constructor after calling the function and all is done the LocalyKeyWords is empty.

This is how im writing to the file today the keys and values:

private void button6_Click(object sender, EventArgs e)
        {

            using (var w = new StreamWriter(keywords))
            {
                crawlLocaly1 = new CrawlLocaly();
                crawlLocaly1.StartPosition = FormStartPosition.CenterParent;
                DialogResult dr = crawlLocaly1.ShowDialog(this);
                if (dr == DialogResult.OK)
                {
                    if (LocalyKeyWords.ContainsKey(mainUrl))
                    {
                        LocalyKeyWords[mainUrl].Clear();
                        LocalyKeyWords[mainUrl].Add(crawlLocaly1.getText());
                    }
                    else
                    {
                        LocalyKeyWords[mainUrl] = new List<string>();
                        LocalyKeyWords[mainUrl].Add(crawlLocaly1.getText());
                    }
                    foreach (KeyValuePair<string, List<string>> kvp in LocalyKeyWords)
                    {
                        w.WriteLine(kvp.Key + "," + string.Join(",", kvp.Value));
                    }
                }
            } 
        }

Maybe now you will be able to solve the loading the keys and values in the constructor and also to solve the problem how to write each time im doing a change of the keys or values in the button6 click event.

Answer 1

string line = System.String.Empty;
using (StreamReader sr = new StreamReader("MyFile.txt")
{
    while ((line = sr.ReadLine()) != null)
    {
         string[] tokens = line.Split(',');    
         LocalKeyWords.Add(tokesn[0], tokens[1]);
    }
}

You should probably wrap that in a try catch as well.
