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";

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>

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"
    """;

您还可以将双引号包含到单引号中。

string str = '"' + "How to add doublequotes" + '"';

你可以用"而不是“。”浏览器将正确地显示它。

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\";
