如何删除“\\\\ n”从一个字符串 [英] how to remove "\r\n" from a string

问题描述

Hellow

从文本文件中，我读了2个字符串，每个字符串都是单行

Hellow
From a text file ,i read 2 strings each one is in single line

str1=sr.ReadLine();
str2=sr.ReadLine();

文本文件如下

scott

miller



i希望将str2附加到str1并在它们之间添加空格

the text file is as below
scott
miller

i want to attache str2 to str1 and add a space between them

str3=str1+ "   " + str2;

因为 \\\\ n在每个字符串中，我没有得到我想要的，

\\\\ n必须删除

我怎么能减去来自str1和str2的\\\\ n

because of the "\r\n" in each string,i did not get whate i want,
"\r\n" must be removed
how can i subtract "\r\n" from both str1 and str2

推荐答案

如果您只想删除\\\\ n，请尝试替换：

If you only want to remove the \r\n, try Replace:

str1 = sr.ReadLine().Replace("\r\n", String.Empty);
str2 = sr.ReadLine().Replace("\r\n", String.Empty);

如果要删除所有尾随空格（如果有的话），包括\\\\ n，你可以使用 TrimEnd ：

If you want to remove all trailing whitespace (if there is any) including \r\n, you can use TrimEnd:

str1 = sr.ReadLine().TrimEnd();
str2 = sr.ReadLine().TrimEnd();
