如何使用LINQ to XML将“输出到XML文件

Question

I am doing some XML parsing, and I want to be able to have an element that looks like the following:

<PostBuildEvent>
   copy &quot;$(BPL_OUTPUT)\$(OUTPUTFILENAME)&quot; &quot;$(QUICKSET_INSTALL)&quot;  
 </PostBuildEvent>

I am using the .NET XDocument class, calling the XDocument.Save() method.

The value of this PostBuildEvent tag is stored in a constant variable, like the following:

public const string PostBuildEventScript = 
  "copy "$(BPL_OUTPUT)\\$(OUTPUTFILENAME)" "$(QUICKSET_INSTALL)"";

I want to copy the value of this variable to this XML element, but what is printed to the XML document is:

<PostBuildEvent>
copy &amp;quot;$(BPL_OUTPUT)\$(OUTPUTFILENAME)&amp;quot; &amp;quot;$(QUICKSET_INSTALL)&amp;quot;
</PostBuildEvent>

As you can see, there's an extra amp; that I don't want. I also tried hard coding the variable like:

public const string PostBuildEventScript = 
         "copy \"$(BPL_OUTPUT)\\$(OUTPUTFILENAME)\" \"$(QUICKSET_INSTALL)\"";

But this resulted in:

<PostBuildEvent>
     copy "$(BPL_OUTPUT)\$(OUTPUTFILENAME)" "$(QUICKSET_INSTALL)"
</PostBuildEvent>

But as you can see, those are actual double quotes and I wanted "&quot".

How do I handle this problem?
