In one of my controller actions I need to read in a text file that has a bunch of reference data in it. Right now I simply put it in the &quot;/Content&quot; directory.

My questions are:

1.  Is this the &quot;right&quot; place to put this file or should I put it in another directory?
2.  What is the best way to read in a text file in asp.net-mvc that is sitting on the server?  

What is the best way to read in a text file from the server in asp.net-mvc

I have an ANSI encoded text file that should not have been encoded as ANSI as there were accented
characters that ANSI does not support. I would rather work with UTF-8.

Can the data be decoded correctly or is it lost in transcoding?

What tools could I use?

Here is a sample of what I have:

    &#195;&#167; &#195;&#169;

I can tell from context (caf&#195;&#169; should be caf&#233;) that these should be these two characters:

    &#231; &#233;



How do I correct the character encoding of a file?

Referring on [this question][1], I have a similar -but not the same- problem..

On my way, I&#39;ll have some text file, structured like:

    var_a: &#39;home&#39;
    var_b: &#39;car&#39;
    var_c: 15.5

And I need that python read the file and then create a variable named var_a with value &#39;home&#39;, and so on.

Example:
    
    #python stuff over here
    getVarFromFile(filename) #this is the function that im looking for
    print var_b
    #output: car, as string
    print var_c
    #output 15.5, as number.

Is this possible, I mean, even keep the var type?

Notice that I have the full freedom to the text file structure, I can use the format I like if the one I proposed isn&#39;t the best.

**EDIT**: the ConfigParser can be a solution, but I don&#39;t like it so much, because in my script I&#39;ll have then to refer to the variables in the file with

    config.get(&quot;set&quot;, &quot;var_name&quot;)

But what I&#39;ll love is to refer to the variable directly, as I declared it in the python script...

There is a way to import the file as a python dictionary?

Oh, last thing, keep in mind that I don&#39;t know exactly how many variables would I have in the text file.

**Edit 2**: I&#39;m very interested at stephan&#39;s JSON solution, because in that way the text file could be read simply with others languages (PHP, then via AJAX JavaScript, for example), but I fail in something while acting that solution:

    #for the example, i dont load the file but create a var with the supposed file content
    file_content = &quot;&#39;var_a&#39;: 4, &#39;var_b&#39;: &#39;a string&#39;&quot;
    mydict = dict(file_content)
    #Error: ValueError: dictionary update sequence element #0 has length 1; 2 is required
    file_content_2 = &quot;{&#39;var_a&#39;: 4, &#39;var_b&#39;: &#39;a string&#39;}&quot;
    mydict_2 = dict(json.dump(file_content_2, True))
    #Error:
    #Traceback (most recent call last):
    #File &quot;&lt;pyshell#5&gt;&quot;, line 1, in &lt;module&gt;
    #mydict_2 = dict(json.dump(file_content_2, True))
    #File &quot;C:\Python26\lib\json\__init__.py&quot;, line 181, in dump
    #fp.write(chunk)
    #AttributeError: &#39;bool&#39; object has no attribute &#39;write&#39;

In what kind of issues can I fall with the JSON format?
And, how can I read a JSON array in a text file, and transform it in a python dict?


P.S: I don&#39;t like the solution using .py files; I&#39;ll prefer .txt, .inc, .whatever is not restrictive to one language.

Using php, I&#39;m trying to create a script which will search within a text file and grab that entire line and echo it.

I have a text file (.txt) titled &quot;numorder.txt&quot; and within that text file, there are several lines of data, with new lines coming in every 5 minutes (using cron job). The data looks similar to:

I would like to create a .txt file and write to it, and if the file already exists I just want to append some more lines:
 

    string path = @&quot;E:\AppServ\Example.txt&quot;;
    if (!File.Exists(path))
    {
        File.Create(path);
        TextWriter tw = new StreamWriter(path);
        tw.WriteLine(&quot;The very first line!&quot;);

    // write a line of text to the file
    tw.WriteLine(DateTime.Now);

    // close the stream

So i can get: 

Button pressed: txt opened -&gt; added current time, then close it. Another button pressed, txt opened -&gt; added text &quot;OK&quot;, or &quot;NOT OK&quot; in the same line, then close it again.

So my txt file will look like that:

    2011-11-24 10:00:00 OK
    2011-11-25 11:00:00 NOT OK

How can i do this? Thanks!
