C＃：linq返回boolean而不是string

Question

我想從長度小於或等於5的列表中選擇所有單詞。我當前的代碼只返回：

1. 真正
2. 假
3. 假
4. 真正
5. 真正
6. 真正

我希望結果是實際的單詞。

static void Main()
{
    string[] words = { "hello", "Welcome", "Rolling", "in", "The", "Deep" };
    var shortWords = from word in words select word.Length <= 5;

    foreach (var word in shortWords) {
        Console.WriteLine(word);
    }

    Console.Read();
}

Answer 1

看起來你打算做

var shortWords = from word in words where word.Length <= 5 select word;

要不就

var shortWords = words.Where(word => word.Length <= 5);
