如何将字符串数组转换为句子？

Question

如何使用Linq查询方法将字符串数组转换为句子？

private static void Main()
{
    string sentence = "C# is fun.";
    string[] words = sentence.Split();
    //string temp= words;       
}

temp希望与sentence具有相同的价值。

Answer 1

您可以使用

var res = string.Join(" ", words);

或

string[] words = { "one", "two", "three" };
var res = words.Aggregate((current, next) => current + " " + next);

Answer 2

您可以尝试：

var temp = words.Aggregate((x, y) => x + " " + y);

Answer 3

string temp = words.Aggregate((workingSentence, next) => 
      workingSentence + " " + next);

Answer 4

使用String.Join方法：

private static void Main()
{
    string sentence = "C# is fun.";
    string[] words = sentence.Split();

    // Join the words back together, with a " " in between each one.
    string temp = String.Join(" ", words);
}
