使用

&dquo
<div>&dquo"+ title +@"&dquo</div>

或者转义双引号:

\"
<div>\""+ title +@"\"</div>

<i class=\"fa fa-check-circle\"></i>"与Eval()数据绑定的三元运算符一起使用:

Text = '<%# Eval("bqtStatus").ToString()=="Verified" ? 
       Convert.ToString("<i class=\"fa fa-check-circle\"></i>") : 
       Convert.ToString("<i class=\"fa fa-info-circle\"></i>"

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");

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>

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

一种间接的，但简单易懂的替代方法，在字符串的开头和结尾添加引号-

char quote = '"';

string modifiedString = quote + "Original String" + quote;
