如何用另一个列表中的项替换文本中的字符串列表?

如果您想使用regex,可以使用以下内容:

var findList = new List<string>() { "boy", "car", "ball" };
var replaceList = new List<string>() { "dog", "bar", "bone" };

// Create a dictionary from the lists or have a dictionary from the beginning.
var dictKeywords = findList.Select((s, i) => new { s, i })
                           .ToDictionary(x => x.s, x => replaceList[x.i]);

string input = "the boy sold his car to buy a ball";
// Construct the regex pattern by joining the dictionary keys with an 'OR' operator.
string pattern = string.Join("|", dictKeywords.Keys.Select(s => Regex.Escape(s)));

string output =
    Regex.Replace(input, pattern, delegate (Match m)
    {
        string replacement;
        if (dictKeywords.TryGetValue(m.Value, out replacement)) return replacement;
        return m.Value;
    });

Console.WriteLine(output);

输出:

那条狗卖掉酒吧买骨头

不需要使用regex, string.Replace 就够了

var input = "the boy sold his car to buy a ball";
var oldvalues = new List<string>() { "boy", "car", "ball" };
var newValues = new List<string>() { "dog", "bar", "bone" };
var output = input;
for (int i = 0; i < oldvalues.Count; i++)
{
    output = output.Replace(oldvalues[i], newValues[i]);
}
Console.WriteLine(output);
