How to escape quote inside a double-quote?

Question

I am adding a table with html:

string _table = @"{
                        ""version"": {""number"": 2},
                        ""type"":""page"",
                        ""title"":""Table"", 
                        ""space"":{""key"":""" + postdata.key + @"""},
                        ""body"":{""storage"":{""value"":""<table><tbody><tr><th><p><strong>Project Basic Informations</strong></p></th></tr></tbody></table>"",""representation"":""storage""}}
                        }";

And I want to style <th> with colspan="2" so the header spans two columns.

I tried the following but it doesn't work:
""<table> <tbody> <tr> <th colspan=""2""> <p><strong>Project Basic Informations</strong></p> </th>....""
or <th colspan=\\"2\\"

Is there a way to escape the double-quotes and get the <th> colspan attribute to work?

Answer 1

single-quote on HTML attributes also works. you can write <th colspan='2'>

Answer 2

Just put the \\ inside the string:

    string table = "\"<table><tbody><tr><th colspan = \"2\"><p><strong> Project Basic Informations</strong></p></th>....\"";

Or you can use the ascii code of the double-qoute:

    char quote = (char)34;
        string table = quote + "<table><tbody><tr><th colspan = " + quote + "2" + quote + "><p><strong> Project Basic Informations</strong></p></th>...." + quote;

Or you can use single-quote asMohammdReza Keikavousi said.

您可以在任何转义字符之前使用 / 或仅使用单引号，例如：“ I/”m StackOverflow “ else “ Im StackOverflow”
