Question

I have declared a dictionary like this:

Dictionary<string, KeyValuePair<string, string>> dc = new Dictionary<string, KeyValuePair<string, string>>();

now how can I loop through it? I wanted something like the following so I created that dictionary:

name1
oldValue1
newValue1

name2
oldValue2
newValue2

…

Answer 1

You can loop through it like so

foreach (var pair in dc)
{
    string name = pair.Key;
    string oldValue = pair.Value.Key;
    string newValue = pair.Value.Value;

    // use the values 
}

But I have a feeling you’re using the wrong tool for the job. It sounds to me like you really need to go ahead and define a proper class to hold the names and values, and then just work with a List<T> of that class.
