LINQ : Dynamic select

Question

Consider we have this class :

    public  class Data
{
    public string Field1 { get; set; }
    public string Field2 { get; set; }
    public string Field

You must use reflection to get and set property value with it's name.

  var result = new List();
  var data = new Data();
  var type = data.GetType();
  var fieldName = "Something";

  for (var i = 0; i < list.Count; i++)
  {
      foreach (var property in data.GetType().GetProperties())
      {
         if (property.Name == fieldName)
         {
            type.GetProperties().FirstOrDefault(n => n.Name == property.Name).SetValue(data, GetPropValue(list[i], property.Name), null);
            result.Add(data);
         }
      }
  }

And here is GetPropValue() method

public static object GetPropValue(object src, string propName)
{
   return src.GetType().GetProperty(propName).GetValue(src, null);
}
