用字符替换单词之间的空格 [英] replacing spaces between words with character

问题描述

您好，



小问题我有

（否则我不会问:)



我需要用另一个字符替换文本框中的空格，我试过



string.Replace



喜欢这个



string text = textbox.Text;



textbox .Text =需要帮助;

text.Replace（，_）;

string text1 = text;



但没有任何反应



而不是，_我试过''，'_'，仍然没有，我试过字符串。空，_，仍然没什么，它会抛出一个错误，那个旧值不能为零长度





我只是想当我在文本框中键入一些文本时，当我按空格键分隔单词时，字符_就在那里，那就是

Hello,

little issue I have
(otherwise I wouldn't be asking :)

I need to replace blank spaces in textbox with another character, I tried

string.Replace

like this

string text = textbox.Text;

textbox.Text = "NEED HELP";
text.Replace(" ", "_");
string text1 = text;

but nothing happens

instead of " ", "_" I tried ' ', '_', still nothing, I tried string.Empty, "_", still nothin, it throws an error on that one that he old value can not be zero length


I just want to while I type in textbox some text when I hit spacebar to divide words a character _ comes there, that's all

推荐答案

你只是忘了指定Replace操作的结果到文本。其他一切都很好。

You just forgot assign result of Replace operation to text. Everything else was/is fine.

text = text.Replace(" ", "_");

string.Replace函数返回一个必须分配给变量的字符串。



解决方案是

string.Replace function returns a string that has to be assigned to variable.

solution is

text1 = text.Replace(@" ", "_");
