如果我理解你的问题，也许你可以试试这个:

string title = string.Format("<div>\"{0}\"</div>", "some text");

在c# 11.0预览版中，你可以使用原始字符串字面值。

Raw string literals are a new format for string literals. Raw string literals can contain arbitrary text, including whitespace, new lines, embedded quotes, and other special characters without requiring escape sequences. A raw string literal starts with at least three double-quote (""") characters. It ends with the same number of double-quote characters. Typically, a raw string literal uses three double quotes on a single line to start the string, and three double quotes on a separate line to end the string.

string str = """
    "How to add double quotes"
    """;

现在是c# 11

var string1 = """before "inside" after""";

var string2 = """ "How to add double quotes" """;

使用工作示例的字符串插值:

var title = "Title between quotes";
var string1 = $@"<div>""{title}""</div>";  // Note the order of the $@
Console.WriteLine (string1);

输出

<div>"Title between quotes"</div>

你可以用"而不是“。”浏览器将正确地显示它。

如果你必须经常这样做，并且你想让代码更干净，你可能会喜欢有一个扩展方法。

这是非常明显的代码，但我仍然认为它可以帮助您节省时间。

  /// <summary>
    /// Put a string between double quotes.
    /// </summary>
    /// <param name="value">Value to be put between double quotes ex: foo</param>
    /// <returns>double quoted string ex: "foo"</returns>
    public static string AddDoubleQuotes(this string value)
    {
        return "\"" + value + "\"";
    }

然后你可以在你喜欢的每个字符串上调用foo. adddoublequotes()或"foo". adddoublequotes()。
