将\\替换为string.empty不起作用
[英]Replace \ with string.empty is not working
问题描述
我正在使用Aspose.Words将Word文档转换为HTML，最后转换为包含该文档所有HTML的字符串。
我遇到的麻烦是替换"\\" 。
这是我从文档中获得的字符串：
htmlString "<html><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" /><meta http-equiv=\"Content-Style-Type\" content=\"text/css\" /><meta name=\"generator\" content=\"Aspose.Words for .NET 13.7.0.0\" /><title></title></head><body><div><p style=\"font-size:12pt; line-height:115%; margin:0pt 0pt 10pt\"><span style=\"color:#ff0000; font-family:Calibri; font-size:12pt; font-weight:bold\">Evaluation Only.

如您所见，它有一堆==”，我需要删除所有\\，然后将其替换为String.Empty。
这是我正在使用的代码：
string htmlString = doc.ToString(SaveFormat.Html);
string text = htmlString.ToString().Replace(@"\", string.Empty);
然而，当我将鼠标悬停在text或添加手表text整个字符串仍然显示所有的\\'s 。 我在这里做错了什么？
这是文本的监视值：

这些实际上不在字符串中。
调试器将显示该字符串的字符串文字，包括转义字符。
要查看字符串的原始值，请使用可视化器（左侧的按钮）

\\实际上并不存在。 只是显示向您显示"不是字符串内容的结尾”
解决方案3

但是，当我将鼠标悬停在文本上或添加文本监视时，整个字符串仍显示所有\\。 我在这里做错了什么？
这只是调试器如何显示值的问题。 实际的文本是：
<html><head><meta http-equiv="Content-Type"
但是调试器使用\\"转义引号
解决方案4

原因是因为它正在向您显示该字符串的字符串值表示形式。在字符串中，要显示双引号字符，您首先必须使用\\ char对其进行转义。 如果将其输出到控制台，则不应看到转义符
