推荐答案

以下步骤可用于将文本文件中的数据读取到List<string> s

The following steps can be used to read the data from the text file into List<string>s

1. 使用File.ReadAllText方法读取文本文件的全部内容，该方法在 http://msdn中解释. microsoft.com/en-us/library/ms143368.aspx [ ^ ]转换为字符串
2. 使用Regex.Split方法(模式为@"}\s*{"
string 拆分为主数组字符串数组>编写一个以string 作为参数并返回List<string>
3. 的方法，在该方法内部使用Regex.Matches方法，其模式为@"{([^{}]*)}"，该模式将{ }中的元素作为组捕获元素
4. 创建一个List<string>，将每个match.Groups[1].Value添加到此列表中，然后返回此构造的列表
5. 将在步骤2中获得的每个string 传递给此方法，以获得每个内部列表

1. Read the entire content of the text file using File.ReadAllText method explained here http://msdn.microsoft.com/en-us/library/ms143368.aspx[^] into a string
2. Split this string into an array of main array strings using Regex.Split method with the pattern @"}\s*{"
3. Write a method which takes a string as parameter and returns a List<string>
4. Inside the method use Regex.Matches method with the pattern @"{([^{}]*)}", which captures the elements within { } as group elements
5. Create a List<string>, add each match.Groups[1].Value to this list and return this constructed List
6. Pass each string obtained in step 2 to this method to obtain each inner list
