C#中的字符串操作.在单词之间插入"+"

Question

这是我所拥有的.我的想法是将字符串填充到数组中,对其进行格式化并将其重新转换为字符串.

    //input search term
    Console.WriteLine("What is your search query?:");
    string searchTerm = Console.ReadLine();

    //stuff the search term into an array to split it out
    string separator = " "; //assumes search terms are separated by spaces
    string[] searchTermArray = searchTerm.Split(separator.ToCharArray());

    //construct the search term
    string searchTermFormat = "";

    for (int i = 0; i < searchTermArray.Length; i++)
    {
        searchTermFormat += searchTermArray[i] + "+";
        //Console.WriteLine(searchTermFormat);
    }

期望的输出

word1+word2+word3

单词数量不固定的地方.

• 您正在寻找 String.Join("+", searchTermArray)
• 你正在努力写作 searchTerm.Replace(' ', '+')
• 你可能应该写作 Uri.EscapeDataString(searchTerm)
