如何使用正则表达式提取带引号的字符串？或者如何在c#中使用这个特定的正则表达式("[^"]*\.csv")？

string pattern = "world";
string input = "hello";
Match match = Regex.Match(input, pattern);
if (match.Success)
{
    string group = match.Groups[0].Value;
    Console.WriteLine(group); // Output: "world"
}

string pattern = "world\.csv";
string input = "hello";
Match match = Regex.Match(input, pattern);
if (match.Success)
{
    string group = match.Groups[0].Value;
    Console.WriteLine(group); // Output: "world.csv"
}

string pattern = @"\bworld\.csv\b";
string input = "hello";
Match match = Regex.Match(input, pattern);
if (match.Success)
{
    string group = match.Groups[0].Value;
    Console.WriteLine(group); // Output: "world.csv"
}
