LINQ查询返回一个Dictionary <string,string>

我有一个MyClass的集合,我希望使用LINQ来查询以获取不同的值,然后返回一个Dictionary <string,string>作为结果,但我无法弄清楚如何做到这一点比我更简单在下面做。 我可以使用哪些更干净的代码来获得Dictionary <string,string>作为我的结果?

var desiredResults = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase);

var queryResults = (from MyClass mc in myClassCollection
                    orderby bp.SomePropToSortOn
                    select new KeyValuePair<string, string>(mc.KeyProp, mc.ValueProp)).Distinct();

foreach (var item in queryResults)
{
    desiredResults.Add(item.Key.ToString(), item.Value.ToString());
}

直接使用ToDictionary方法。

var result = 
  // as Jon Skeet pointed out, OrderBy is useless here, I just leave it 
  // show how to use OrderBy in a LINQ query
  myClassCollection.OrderBy(mc => mc.SomePropToSortOn)
                   .ToDictionary(mc => mc.KeyProp.ToString(), 
                                 mc => mc.ValueProp.ToString(), 
                                 StringComparer.OrdinalIgnoreCase);

查看ToLookup和/或ToDictionary扩展方法。
