使用C#Regex从大字符串中提取特定的JSON

Question

下面是一个示例字符串：

public class Person
{
   public string firstName;
   public string lastName;
}

{"firstName":"John", "lastName":"Doe"},
{"firstName":"Anna", "lastName":"Smith"},
{"firstName":"Peter", "lastName":"Jones"}

{"firstName":"John", "middleName":"", "lastName":"Doe"},
{"firstName":"Anna", "lastName":"Smith", "age":""},
{"firstName":"Peter", "lastName":"Jones" some text}

{"firstName":"[val]", "lastName":"[val]"}

Answer 1

下面是一个可以用来提取值的regex：

({\s*"firstName":\s*"[^"]+",\s*"lastName":\s*"[^"]+"\s*})

在此之后，我建议只使用JSON.NET来反序列化对象。
