double quotes inside double quotes

Question

我正在将以下连接字符串写入web.config，但它给了我error.what正确的写入方式是什么？

<add name="stargaze_stargazeConnectionString1" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename="D:\Work At DS\19th Jan\myastrolove.com_new\App_Data\dbName.mdf";Integrated Security=True;User Instance=True"/>

Answer 1

web.config is XML, so you need to escape the inner quotes to " :

<add name="stargaze_stargazeConnectionString1" 
connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=&quot;D:\Work At DS\19th Jan\myastrolove.com_new\App_Data\dbName.mdf&quot;;Integrated Security=True;User Instance=True"/>

Answer 2

Inside the string, replace " with \\" to properly escape it.

That means that your string should look like this:

"<add name=\"stargaze_stargazeConnectionString1\" connectionString=\"Data Source=.\SQLEXPRESS;AttachDbFilename=\"D:\Work At DS\19th Jan\myastrolove.com_new\App_Data\dbName.mdf\";Integrated Security=True;User Instance=True\"/>"

Answer 3

不应该是这样的：

<add name="stargaze_stargazeConnectionString1" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=\"D:\Work At DS\19th Jan\myastrolove.com_new\App_Data\dbName.mdf\";Integrated Security=True;User Instance=True"/>
