You could also use string[] something = text.Split('@'). Make sure you use single quotes to surround the "@" to store it as a char type. This will store the characters up to and including each "@" as individual words in the array. You can then output each (element + System.Environment.NewLine) using a for loop or write it to a text file using System.IO.File.WriteAllLines([file path + name and extension], [array name]). If the specified file doesn't exist in that location it will be automatically created.

你可以在@符号后面添加一个新的行字符，如下所示:

string newString = oldString.Replace("@", "@\n");  

你也可以在环境类中使用NewLine属性(我认为它是环境)。

一个简单的字符串替换就可以完成这项工作。看看下面的示例程序:

using System;

namespace NewLineThingy
{
    class Program
    {
        static void Main(string[] args)
        {
            string str = "fkdfdsfdflkdkfk@dfsdfjk72388389@kdkfkdfkkl@jkdjkfjd@jjjk@";
            str = str.Replace("@", "@" + Environment.NewLine);
            Console.WriteLine(str);
            Console.ReadKey();
        }
    }
}

然后将之前的答案修改为:

Console.Write(strToProcess.Replace("@", "@" + Environment.NewLine));

如果您不希望文本文件中出现换行符，那么就不要保存它。

string str = "fkdfdsfdflkdkfk@dfsdfjk72388389@kdkfkdfkkl@jkdjkfjd@jjjk@";
str = str.Replace("@", Environment.NewLine);
richTextBox1.Text = str;

更改您的字符串如下所述。

string strToProcess = "fkdfdsfdflkdkfk"+ System.Environment.NewLine +" dfsdfjk72388389"+ System.Environment.NewLine +"kdkfkdfkkl"+ System.Environment.NewLine +"jkdjkfjd"+ System.Environment.NewLine +"jjjk"+ System.Environment.NewLine;
