c# - 拆分和组合两个不同的字符串

Question

我正在尝试创建一个字符串，下面是我想要实现的目标:

String first = "Previous.value1 | Previous.value2";
String second = "New.value1| New.value2";

我正在尝试创建这样的最终字符串:

string final ="generate Previous.value1 cross New.value1 ? Previous.value1 cross New.value2";

但是问题是当我出现如下不匹配时:

String first = "Previous.value1 | Previous.value2";
String second = "New.value1";

然后我想要这样，因为我在第二个变量中没有Previous.Value2的匹配值:

string final ="generate Previous.value1 cross New.value1";

到目前为止，当两个字符串中的值数量相同时，我成功生成了最终字符串。

string final = "generate";
if (first.Split('|').Count() - second.Split('|').Count() == 0)
{
    int i = 0;
    foreach (var item in first.Split('|').Count())
    {
        if (i == 0)
            final = final + item + " cross " + second.Split('|')[i];
        else
            final = final +  " ? " + item + " cross " + second.Split('|')[index];
        i++;
    }
}

尝试此 LINQ 查询(使用 the Zip extension method ):

var zippedQry = first.Split('|').Zip(second.Split('|'),
    (f, s) => f.Trim() + " cross " + s.Trim());
string final = "generate " + String.Join(" ? ", zippedQry.ToArray());
