linq变量到c中的datagridview

我在Linq中有一个简单的查询，它按字长获取字符组，下面是代码

string sentence = "This is sample linq query";
            string[] words =  sentence.Split(' ');

            var query = from word in words
                        group word by word.Length into gr
                        orderby gr.Key ascending
                        select new { Length = gr.Key, Words = gr };

            foreach (var obj in query)
            {
                Console.WriteLine("Word of Length: {0}", obj.Length);
                foreach (string word in obj.Words)
                {
                    Console.WriteLine("{0}", word);
                }
                Console.WriteLine();
            }

它工作正常，现在我想通过将上述记录放入DataGridView，将其转换为windows窗体应用程序，因此我实现如下

string sentence = "This is sample linq query";
            string[] words = sentence.Split(' ');

            var query = from word in words
                        group word by word.Length into gr
                        orderby gr.Key ascending
                        select new { Length = gr.Key, Words = gr };


            dataGridView1.DataSource = query.ToList();

但是在这里，我只得到DataGridView中的第一列长度，而不是Word列，我还需要做些什么才能得到这两列。

在您的例子中，分组中的Word部分由一个IGrouping组成，它不能由datagrid显示。尝试按如下方式连接单词：

var query = from word in words
    group word by word.Length into gr
    orderby gr.Key ascending
    select new { Length = gr.Key, Words = gr.Aggregate((left, right)=>string.Format("{0}, {1}", left, right)) };

然后您将在网格中看到两列，一列的长度为，另一列的长度为现在再次连接的相同长度的单词
