问题描述

推荐答案

string bla = "abc\r\ndef\r\nghijk";
string [] splitter = { "\r\n" };
string [] foo = bla.Split(splitter, StringSplitOptions.RemoveEmptyEntries);

或使用Streams，可能会从文件中获取此字符串.但这仅在您具有CR/LF分离器"的情况下有效.

or with Streams, probably you get this string out of a file. But this only works in cases where you habe CR/LF "Splitters".

string bla = "abc\r\ndef\r\nghijk";
using (StringReader sr = new StringReader(bla))
{
    string line = string.Empty;
    do
    {
        line = sr.ReadLine();

        if (line != null)
        {
            Debug.WriteLine(line);

        }

    } while (line != null);
}

这有帮助吗?

Does this help?

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main()
    {
    string value = "cat\r\ndog\r\nanimal\r\nperson";
    //
    // Split the string on line breaks.
    // ... The return value from Split is a string[] array.
    //
    string[] lines = Regex.Split(value, "\r\n");

    foreach (string line in lines)
    {
        Console.WriteLine(line);
    }
    }
}

解决方案2很好.

但是，如果有空白，我认为它们可能不会被删除.

The Solution 2 is very good.

But, if there are empty spaces, I think they may not be deleted.

void Main()
    {
    string input= "First Line\r\nSecond Line\r\n\r\nThird Line";
    string[] lines = input.Split(new string[]{"\r\n"},
                    StringSplitOptions.RemoveEmptyEntries);
    foreach (string line in lines)
    {
        Console.WriteLine (line);
    }
}
//First Line
//Second Line
//Third Line

在上面显示的示例中，在SecondLine之后，由于\ r \ n的替换，因此有一个空条目.使用StringSplitOptions.RemoveEmptyEntries选项可以删除此空条目.

In the sample shown above after SecondLine there is an empty entry due to repition of \r\n. With StringSplitOptions.RemoveEmptyEntries option this empty entry can removed.
