在c#中添加换行符到字符串中

小开

最佳答案

在任何字符串中使用Environment.NewLine。一个例子:

string text = "fkdfdsfdflkdkfk@dfsdfjk72388389@kdkfkdfkkl@jkdjkfjd@jjjk@";


text = text.Replace("@", "@" + System.Environment.NewLine);

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Environment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();
}
}
}

前面的答案很接近，但为了满足@符号保持接近的实际要求，你会希望它是str.Replace("@", "@" + System.Environment.NewLine)。这将保留@符号，并为当前平台添加适当的换行符。

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。

根据你对其他人的回复，这就是你想要的。

string file = @"C:\file.txt";
string strToProcess = "fkdfdsfdflkdkfk@dfsdfjk72388389@kdkfkdfkkl@jkdjkfjd@jjjk@";
string[] lines = strToProcess.Split(new char[] { '@' }, StringSplitOptions.RemoveEmptyEntries);


using (StreamWriter writer = new StreamWriter(file))
{
foreach (string line in lines)
{
writer.WriteLine(line + "@");
}
}

正如其他人所说，new line char将在windows中的文本文件中给你一个新行。

using System;
using System.IO;


static class Program
{
static void Main()
{
WriteToFile
(
@"C:\test.txt",
"fkdfdsfdflkdkfk@dfsdfjk72388389@kdkfkdfkkl@jkdjkfjd@jjjk@",
"@"
);


/*
output in test.txt in windows =
fkdfdsfdflkdkfk@
dfsdfjk72388389@
kdkfkdfkkl@
jkdjkfjd@
jjjk@
*/
}


public static void WriteToFile(string filename, string text, string newLineDelim)
{
bool equal = Environment.NewLine == "\r\n";


//Environment.NewLine == \r\n = True
Console.WriteLine("Environment.NewLine == \\r\\n = {0}", equal);


//replace newLineDelim with newLineDelim + a new line
//trim to get rid of any new lines chars at the end of the file
string filetext = text.Replace(newLineDelim, newLineDelim + Environment.NewLine).Trim();


using (StreamWriter sw = new StreamWriter(File.OpenWrite(filename)))
{
sw.Write(filetext);
}
}
}

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

你也可以使用string[] something = text.Split('@')。确保使用单引号括住“@”，将其存储为char类型。这将把每个“@”之前的字符作为单独的单词存储在数组中。然后，您可以使用for循环输出每个(element + System.Environment.NewLine)或使用System.IO.File.WriteAllLines([file path + name and extension], [array name])将其写入文本文件。如果指定的文件在该位置不存在，它将自动创建

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;
