问题描述
我遇到了代码块错误。当我在Cs文件中按我的按钮。
错误是控件集合无法修改，因为控件包含代码块（即<％...％>）。

解决方案
您的问题可能来自以下几行：
< pre lang =c＃> dispString = dispString + < th class = printHeaderText style = width：10％; text-align：left; border-removedsolid 1px grey; > LnNo< / th>;
首先，当你试图在字符串中加入一些双引号时，你必须对它们进行esacepe，因此它们不被视为双引号字符串分隔符。
但最好的选择可能是在这里使用StringBuilder，因为你连接几个字符串;性能甚至可以提高。
所以你的代码应该是这样的：
StringBuilder sb = new StringBuilder（ < table cellspacing = \0\\ \\cellpadding = \2 \class = \fullborder \style = \background-color：FFFFE5; width：100％; font-size：11px; font-family：Verdana; \ > 中）;
sb.Append（ < th class = \printHeaderText \style = \ width：10％; text-align：left; border-removedsolid：1px \mode = \hold\/>
sb.Append（< th class = \ printHeaderText \style = \width ：10％; text-align：left; border-removedsolid：1px = \mode = \hold\/>
sb.Append（< th class = \ printHeaderText \style = \width ：10％; text-align：left; border-removedsolid：1px \mode = \hold\/>
// ...等等。
< / table>
StringBuilder.AppendFormat（string，params object []）方法也很有用。
需要记住的重要事项是：如果你想插入双 - 在字符串中引用，你要么要转义双引号本身（用'\'字符），要么加倍它（''）。
示例：
想象一下你要存储句子：
我想插入登录我的字符串。
in a string。
你可以写：
string text = 我想插入\\ \\登录我的字符串。;
或
string text = 我想插入 在我的字符串中签名。;
嗨请尝试这个，这肯定会解决你的问题。
src =<％＃ResolveUrl（'../ js / script.js'）％>
只需在双引号中使用单引号，因此您应该在该页面中使用ResolveUrl Function的地方应用此项。

} 解决方案
Your problem may come from the lines like the following one:
dispString = dispString + "<th class="printHeaderText" style="width:10%;text-align:left;border-removedsolid 1px gray;">LnNo</th>";
First, as you are trying to put some double-quotes in a string, you have to esacepe them, so they are not considered as double-quote string delimiters.
But the best option may be to use a StringBuilder here, as you concatenate several strings alltogether ; performance could even be improved.
So your code should look like:
StringBuilder sb = new StringBuilder("<table cellspacing=\"0\" cellpadding=\"2\" class=\"fullborder\" style=\"background-color:FFFFE5;width:100%;font-size:11px;font-family:Verdana;\">"); sb.Append("<th class=\"printHeaderText\" style=\"width:10%;text-align:left;border-removedsolid:1px\" mode=\"hold\" /> sb.Append("<th class=\"printHeaderText\" style=\"width:10%;text-align:left;border-removedsolid:1px=\" mode=\"hold\" /> sb.Append("<th class=\"printHeaderText\" style=\"width:10%;text-align:left;border-removedsolid:1px\" mode=\"hold\" /> // ... and so on. </table>
TheStringBuilder.AppendFormat(string, params object[])method could also be useful.
Important thing to remeber is: if you want to insert double-quotes in a string, you have either to escape the double-quote itself (with the '\' character), or double it ('""').
Example:
Imagine you want to store the sentence:
I want to insert the " sign in my string.
in a string.
You can write:
string text = "I want to insert the \" sign in my string.";
OR
string text = "I want to insert the "" sign in my string.";
Hi Please try this one this will definitely solve your problem.
src="<%# ResolveUrl('../js/script.js') %>"
Just use single quote inside double quote , so you should apply this where you used ResolveUrl Function in that page.
