Hi,

How can I run attached c# code in page_load or form load event by proving the following STL file?

Hello again.

Take the stlutil class and add it to your aspnet project.
If the file is on the server then put it in the physical directory where you deploy your web app.
In your form load use the same code from class main but pass the args array to IsValidated like thid:
var stlutils=new STLUtils();
If(stlutils.IsValidated(new string[]{filename,STLUtils.LengthType.inch.ToString()}));

The filename argument is the location of the .stl file in the server.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I tried the code but ended up with a syntax error.

ERROR: Possible mistaken empty statement at ';' in the end of the statement.

    protected void Page_Load(object sender, EventArgs e)
    {
        var stlutils = new STLUtils();
        if (stlutils.IsValidated(new string[] { Server.MapPath("~/website1/Part1_full tray..stl"), STLUtils.LengthType.inch.ToString() }));
    }

instead of red underline for syntax error it is green underline and when debugging, not showing error.

as I told you, a syntax error and when I run no result in the page. Actually I expect to execute CalculateVolume function and return result.

ok i understand where the error came from, u left semicolon at the end of the if statement.
try this:

  var stlutils = new STLUtils();
        if (stlutils.IsValidated(new string[] { Server.MapPath("~/website1/Part1_full tray..stl"), STLUtils.LengthType.inch.ToString() })){



}

i didn't realize it can be open in any text editor... (i wasn't familiar with the file type).
did u try it?
do you see the figures?
cause it would make it so much easier to process it as if it was a text file rather binary file like you had in php.
what do u think?
