如何通过列名实体框架linq获取值？

Question

I have a list of column names. I want to iterate fetched data using list of column names, so what generic type should I use to convert fetched data into?

Edit:

List<string> columns = new List<string>();
columns.Add("column1");
columns.Add("column2");
columns.Add("column3");

string joinColumns = string.Join(",", columns);
string sql = "select "+joinColumns+" from Table";

It will fetched only selected columns, So how would I do same functionality using entity framework instead of using sql query?

Thanks in advance. Help is appreciated.

Solution- This is not possible in link so alternative to this, I converted List to DataTable using extension method described in the link - https://stackoverflow.com/a/5805044/1416033

List<string> columns = new List<string>();
columns.Add("column1");
columns.Add("column2");
columns.Add("column3");

List<Accounts> accountList = GetAccountList();
DataTable dt = accountList.ToDataTable<Accounts>();
foreach (DataRow dr in dt.Rows)
{
   foreach (string column in columns)
   {
      val = dr[column].ToString();
   }
}

What you describe isn't going to work with native LINQ functionality. There is a library though, that should help you. Check out Dynamic LINQ: http://weblogs.asp.net/scottgu/archive/2008/01/07/dynamic-linq-part-1-using-the-linq-dynamic-query-library.aspx
