.Replace（Environment.NewLine，“ <br /> “）在localhost上工作，但在我将网站上传到主机时则不行

Question

I have no idea why is that. Here is my code and it works perfectly when I try it on localhost but when I upload my website my text has no <br /> 's. Why this could happen? And how can I fix this issue with new lines? ( white-space: pre-line; is not a solution for me, it is not working on IE6 and it is messing with my styles)

@Html.Raw(Html.Encode(Model.Body)
.Replace(Environment.NewLine, "<br />"))<br />

Answer 1

我相信这个答案是最好的： https ： //stackoverflow.com/a/8196219/550975

string result = Regex.Replace(input, @"\r\n?|\n", "<br />");

Answer 2

As BuildStarted mentioned in the comments, the browsers might either send \\r\\n or \\n , which will break, if you use Environment.NewLine - and I don't think asp.net will fix that up before running your code.

I'd suggest you use a regular expression to replace linebreaks instead: "\\\\r?\\\\n" This should match both cases (I don't expect any browser to actually use '\\r' only).

Answer 3

A lot has happened since IE6 (thank god!) so I would just like mention the CSS solution to the problem.

In your C#:

ViewBag.StringText = "some text" + Environment.NewLine + "more text in a new line";

In your CSS:

.newlines { 
  white-space:pre-line; 
}

In your Razor:

<div class="newlines">@ViewBag.StringText</div>

不要使用Environment.NewLine ，请尝试以下方法：

someString.Replace(@"\r\n", "<br/>");
