推荐答案

尝试类似的方法:

Try something like:

StringBuilder sb = new StringBuilder();
// to keep double quotes in it, it was escaped by '\'
sb.Append("Some text in here with \"this\" in double quotes");
sb.Replace(@'"', @'\"');

更新:
根据更新后的问题，OP需要:

UPDATE:
Based on the updated question, OP needs:

String ex="testing "is" always good";
//I Need output as : testing is \" is \" always good

为此，听起来，他想在这里再加一个反斜杠.不知道为什么，现在我不问了，所以尝试:

For this, it sounds like, he wants to have a extra back slash here. No idea why and now I am not going to ask, so try:

StringBuilder sb = new StringBuilder();
// to keep double quotes in it, it was escaped by '\'
sb.Append("Some text in here with \"this\" in double quotes");
sb.Replace(@'"', @'\\"');

是这样，您可以将其放入数据库中吗?如果是这样，则您正在执行他们所谓的转义"字符，您需要执行以下操作:

Is this so you can put it into a database? If so, you''re doing what they call "escaping" a character, and you need to do this:

StringBuilder sb = new StringBuilder("This is a ""test"" string");
sb.Replace("\"", "\"\"");

如果没有，我想不出您想要这样做的任何原因，但是您需要这样做:

If not, I can''t think of any reason you''d want to do this, but you need to do this:

StringBuilder sb = new StringBuilder("This is a ""test"" string");
sb.Replace("\"", "\\\"");
