将SQL表读入Dictionary <string,List <string [] >>

Question

我有一个如下所示的SQL表:

AAA, Amanda, Anthony
AAA, Anna, Andrew
BBB, Boris, Benji
BBB, Blondie, Bobby

我正在尝试使用SQL数据读取器读取数据,然后将结果插入到 Dictionary<string, List<string[]>>

预期的结果是:

[Key]
   "AAA"
[Value]
   "Amanda", "Anthony"
   "Anna", "Andrew"
[Key]
   "BBB"
[Value]
   "Boris", "Benji"
   "Blondie", "Bobby"

请帮忙:

using (SqlConnection cnn = new SqlConnection("connection"))
{
   using (SqlCommand cmd = new SqlCommand("command", cnn))
   {
      using (SqlDataReader rdr = cmd.ExecuteReader())
      {
         while (rdr.Read())
            {
               ... ?
            }
      {
   {
}

Answer 1

与此类似的东西：

 var dict = new Dictionary<string, List<string[]>>();
 while (rdr.Read())
 {
     // TODO: extract field1, field2, field3
     if(dict.ContainsKey(field1))
     {
         // Add the values to the existing list
         dict[field1].Add(new string [] {field2 , field3});
     }
     else
     {
         //Create a new list and set the initial value
         dict[field1] = new List<string[]> { new string[] { field2 , field3 } };
     }
 }
