双引号内的双引号

Question

我正在将以下连接字符串写入web.config 但它给了我错误。写它的正确方法是什么？

<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，因此您需要将内部引号转义为"：

<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

在字符串中，将"替换为\"以正确转义它。

这意味着你的字符串应如下所示：

"<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"/>
