CString and associated containers define their character type according to the UNICODE settings in the file. You can either stick to wofstream if your program always follows UNICODE character set. Otherwise, please enclose the definition as below. So you can make sure your program will compile in UNICODE and ASCII/MBCS character set.

<pre><code>#ifdef UNICODE
typedef ofstream tstream;
#else
typedef wofstream tstream;
#endif

tstream myfile("example.txt");
</code></pre>

It is good to see about BOM characters and some caveats on reading/writing Unicode strings.

<pre><code>CStringList stringListDev;

Let me rewrite your code like this.

<pre><code>CStringList stringListDev; // CStringList doesn't need to be a pointer.
 .....
 .....
 .....
 ..... 
 ofstream myfile("example.txt");
 for(int i=0; i&lt;stringListDev.Count; i++)
 {
 myfile &lt;&lt; stringListDev[i].GetBuffer(stringListDev[i].GetLength());
 stringListDev[i].ReleaseBuffer();
 }
</code></pre>

<code>CStringList</code> class contains the list of <code>CString</code> objects which is another MFC class. for <code>cout</code>, I think you need an <code>LPTSTR</code> as input. So, use <code>GetBuffer()</code> function to get the same and don't forget to call <code>ReleaseBuffer()</code>. For more info, See <a href="http://msdn.microsoft.com/en-us/library/aa314880%28v=vs.60%29.aspx%29" rel="nofollow">the documentation</a>

From my experience, Passing the GetBuffer with no arguments (default parameter is 0) also returns a pointer to string and you don't need to call <code>ReleaseBuffer()</code> as it returns the pointer to original string without any memory allocation. but I don't recommend that as it is not in the documentation.

blocks|key|1696854|text|如果它符合您的目的，您可以使用CStringList::Serialize将对象的内容写入文件。参见示例代码：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1696855|CStringList+csList;

If it serves your purpose, you can use the <code>CStringList::Serialize</code> to write the contents of your object to a file.
See the sample code:
<pre><code>CStringList csList;
csList.AddTail( L&quot;A&quot; ); // Filling sample data
csList.AddTail( L&quot;B&quot; );
csList.AddTail( L&quot;C&quot; );
CFile File( L&quot;foo.txt&quot;, CFile::modeCreate | CFile::modeWrite ); // File opened using CFile object
CArchive Arch( &amp;File, CArchive::store , MAX_PATH ); // Assign it to CArchive object
csList.Serialize( Arch ); // Call Serialize
Arch.Close();
File.Close();
</code></pre>
This code write the contents of <code>csList</code> to <code>foo.txt</code> as binary data. You can load it to an object by similar way.

Instead of writing your own class, you should use <code>std::vector</code> and <code>std::string</code> as:

<pre><code>#include &lt;vector&gt;
#include &lt;string&gt;

std::vector&lt;std::string&gt; stringArray;

stringArray.push_back("some string");
stringArray.push_back("some other string");
//..

for(size_t i = 0 ; i &lt; stringArray.size(); i++ )
 std::cout &lt;&lt; stringArray[i] &lt;&lt; std::endl;
</code></pre>

And you can also use <code>myfile</code> in place of <code>std::cout</code> in the above code.

You can also replace the <code>for</code> loop with this:

<pre><code>#include &lt;iterator&gt;
#include &lt;algorithm&gt;

std::copy(stringArray.begin(), stringArray.end(), 
 std::ostream_iterator&lt;std::string&gt;(myFile,"\n"));

<code>CStringList</code> have <code>GetAt(pos)</code> method, which returns <code>CString</code>.
To output <code>CString</code> to <code>ofstream</code> use <code>CT2A</code>.

And don't forget close file:

myfile &lt;&lt; (LPCTSTR) stringListDev-&gt;getAt(i);

As a side note: MFC is pretty archaic in structure and design compared to the standard library, and I would recommend to only use them if strictly needed for interfacing with other MFC code (CDialog, etc.)

I am new to C++. I was just going through some code and got this doubt.

The code had some CStringList defined somewhere. I wanted to print that to a file. So I wrote the below code

<pre><code> CStringList *stringListDev;

 .....
 .....
 ..... 
 ofstream myfile("example.txt");
 for(int i=0; i&lt;stringListDev-&gt;Count; i++)
 {
 myfile &lt;&lt; stringListDev[i];
 }
</code></pre>

I was getting an error saying &lt;&lt; not defined on list or something.
