Question

I have a dictionary with several items in it:

public static Dictionary<string, string> vmDictionary = new Dictionary<string, string>();

And I have a method to add the items from within it to a listbox:

        foreach (KeyValuePair<String, String> entry in MyApp.vmDictionary)
        {
            ListViewItem item = new ListViewItem();
            item.SubItems.Add(entry.Value[0]);
            item.SubItems.Add(entry.Value[1]);
            selectVMListView.Items.Add(

}

Although I get the following error:

Error 2 Argument 1: cannot convert from ‘char’ to ‘string’

Relating to these lines:

            item.SubItems.Add(entry.Value[0]);
            item.SubItems.Add(entry.Value[1]);

entry.Value[0] and [1] should be string if I am not mistaken, but for some reason its complaining they are chars :S

Answer 1

entry.Value returns the value component of the KeyValuePair<,>, which in this case is a string, when you then use an index on this string, you are getting a char. I think what you mean to have is the following:

item.SubItems.Add(entry.Key);
item.SubItems.Add(entry.Value);
