我有一个对象列表

public class sample
{
 public DateTime Date;
 public string content;
}

我希望能够创建一个新对象列表

public class sampleWithIntervals
{
 public DateTime startDate;
 public DateTime endDate;
 public string content;
}

应根据内容将样本对象分组为间隔.间隔可以仅包括原始样本列表中包含的那些日期.我不知道如何在Linq做到这一点.

样本数据:

{"10/1/2013", "x"}
{"10/2/2013", "x"}
{"10/2/2013", "y"}
{"10/3/2013", "x"}
{"10/3/2013", "y"}
{"10/10/2013", "x"}
{"10/11/2013", "x"}
{"10/15/2013", "y"}
{"10/16/2013", "y"}
{"10/20/2013", "y"}

This should give me 
{"10/1/2013","10/3/2013", "x"}
{"10/2/2013","10/3/2013", "y"}
{"10/10/2013","10/11/2013", "x"}
{"10/15/2013","10/16/2013", "y"}
{"10/20/2013","10/20/2013", "y"}
