看this回答推理为何/转义和非特殊字符会发生什么

我有一个字符串,它看起来像这样解析后。此字符串来弗朗一个javascript行。
I have a string that looks like this after parsing. This string comes fron a javascript line.
var="http:\/\/www.site.com\/user"
我抓住报价的内侧,以便所有我已经是的http:\ / \ / www.site.com \ /用户
。我如何正确地转义字符串?所以它的 http://www.site.com/user
?我使用.NET
I grabbed the inside of the quote so all i have is http:\/\/www.site.com\/user
. How do i properly escape the string? so its http://www.site.com/user
? I am using .NET
使用与string.replace()方法:
string expr = @"http:\/\/www.site.com\/user"; // That's what you have.
expr = expr.Replace("\\/", "/"); // That's what you want.
这,或者:
expr = expr.Replace(@"\/", "/");
请注意,上面不与空字符串替换出现的 \
,以防万一,你必须支持包含其他合法反斜杠字符串。如果不这样做,你可以写:
Note that the above doesn't replace occurrences of \
with the empty string, just in case you have to support strings that contain other, legitimate backslashes. If you don't, you can write:
expr = expr.Replace("\\", "");
或者,如果你preFER常量文字:
Or, if you prefer constants to literals:
expr = expr.Replace("\\", String.Empty);
