雙引號內的雙引號

Question

我正在將以下連接字符串寫入web.config，但它給了我error.what正確的寫入方式是什么？

<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是XML，因此您需要將內部引號轉義為" ：

<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

在字符串內部，替換" with \\"以正確地逃避它。

這意味着你的字符串應如下所示：

"<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

不應該是這樣的：

<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"/>
