'Convert' Dictionary into List<object>

Question

I have a Dictionary dictionary1 and I need to convert it into a List where Data has the properties lab

Answer 1

.NET already has a data type that does what Data would do: KeyValuePair<T1,T2>. Dictionary already implements IEnumerable<KeyValuePair<T1,T2>>, just cast to it.

Dictionary<string, int> blah = new Dictionary<string, int>();
IEnumerable<KeyValuePair<string, int>> foo = blah;

Answer 2

This is a old post, but post only to help other persons ;)

Example to convert any object type:

public List<T> Select<T>(string filterParam)
{    
    DataTable dataTable = new DataTable()

    //{... implement filter to fill dataTable }

    List<Dictionary<string, object>> rows = new List<Dictionary<string, object>>();
    Dictionary<string, object> row;

    foreach (DataRow dr in dataTable.Rows)
    {
        row = new Dictionary<string, object>();
        foreach (DataColumn col in dataTable.Columns)
        {
            row.Add(col.ColumnName, dr[col]);
        }
        rows.Add(row);
    }

    string json = new JavaScriptSerializer().Serialize(rows);

    using (MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(json)))
    {
        DataContractJsonSerializer deserializer = new DataContractJsonSerializer(typeof(T[]));
        var tick = (T[])deserializer.ReadObject(stream);
        return tick.ToList();
    }
}

Answer 3

I assume that "no loop" actually means "i want LINQ":

List<Data> = dictionary1.Select(
    pair => new Data() {
        label = pair.Key,
        value = pair.Value
    })).ToList();
