How to insert an item into a key/value pair object?

Question

Ok...here\'s a softball question...

I just need to be able to insert a key/value pair into an object at a specific position. I\'m currently working with a Hashtable whic

Answer 1

List> kvpList = new List>()
{
    new KeyValuePair("Key1", "Value1"),
    new KeyValuePair("Key2", "Value2"),
    new KeyValuePair("Key3", "Value3"),
};

kvpList.Insert(0, new KeyValuePair("New Key 1", "New Value 1"));

Using this code:

foreach (KeyValuePair kvp in kvpList)
{
    Console.WriteLine(string.Format("Key: {0} Value: {1}", kvp.Key, kvp.Value);
}

the expected output should be:

Key: New Key 1 Value: New Value 1
Key: Key 1 Value: Value 1
Key: Key 2 Value: Value 2
Key: Key 3 Value: Value 3

The same will work with a KeyValuePair or whatever other type you want to use..

Edit -

To lookup by the key, you can do the following:

var result = stringList.Where(s => s == "Lookup");

You could do this with a KeyValuePair by doing the following:

var result = kvpList.Where (kvp => kvp.Value == "Lookup");

Made the answer specific to KeyValuePair rather than string.
