How can I put quotes in a string?

问题

I need to write a string literal to a text file, but the C# compiler finds errors when I use quote characters in it.

My current code:

writeText.WriteLine("<?xml version="1.0" encoding="utf-8"?>");

I need the output for the text file to be:

<?xml version="1.0" encoding="utf-8"?>

How can I put quote characters in strings in C#?

回答1:

You need to escape the quotation marks to put them in a string. There is two ways of doing this. Using backslashes in a regular string:

writeText.WriteLine("<?xml version=\"1.0\" encoding=\"utf-8\"?>");

Using double quoation marks in a @-delimited string:

writeText.WriteLine(@"<?xml version=""1.0"" encoding=""utf-8""?>");

回答2:

Try

writeText.WriteLine("<?xml version=\"1.0\" encoding=\"utf-8\"?>");

Have a look at "What character escape sequences are available?" of the C# FAQ

回答3:

Since to XML both " and ' can used, try

writeText.WriteLine("<?xml version='1.0' encoding='utf-8'?>");
