请帮我正则表达式或其他方法

试试这个：

Try this:

string result = Regex.Match(input, "\"text\":\"(?<txt>[^,\"]+)\"").Groups["txt"].Value;

如果您有多个 text 变量输入，试试这个：

If you have more than one text variable in your input, try this:

string[] results = Regex.Matches(input, "\"text\":\"(?<txt>[^,\"]+)\"").Cast<Match>().Select(x => x.Groups["txt"].Value).ToArray();

希望这会有所帮助。

Hope this helps.
