我有一个这样的字符串变量:
string title = string.empty;
我必须在双引号内的div中显示传递给它的任何内容。我写过这样的东西:
...
...
<div>"+ title +@"</div>
...
...
我怎么在这里加双引号?这样它就会像这样显示:
"How to add double quotes"

当前回答
string doubleQuotedPath = string.Format(@"""{0}""",path);

所以你本质上是问如何存储双引号在一个字符串变量?有两个解决方案:
var string1 = @"""inside quotes""";
var string2 = "\"inside quotes\"";
为了让大家更清楚发生了什么:
var string1 = @"before ""inside"" after";
var string2 = "before \"inside\" after";
你可以用"而不是“。”浏览器将正确地显示它。
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"
""";
如果您还想向包含动态值的字符串添加双引号。同样,在CodeId[i]和CodeName[i]的地方,您可以放入动态值。
data = "Test ID=" + "\"" + CodeId[i] + "\"" + " Name=" + "\"" + CodeName[i] + "\"" + " Type=\"Test\";
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()。
