Memory error

What actually is the code trying to do?

Will finally save to a file

you have to write directly to file. Associate your writer with a FileStream.

What he said!

try with this:

TextWriter sw =  new StreamWriter("somefile.html");
HtmlTextWriter htw = new HtmlTextWriter(sw);
 
foreach (Table table in tables)
{
     table.RenderControl(htw);
}
htw.Close();

Select allOpen in new window

The above code still saves only part of the data to the file "somefile.html"

what do you mean with "part of the data" ?

try to use Flush:
TextWriter sw =  new StreamWriter("somefile.html");
HtmlTextWriter htw = new HtmlTextWriter(sw);
 
foreach (Table table in tables)
{
     table.RenderControl(htw);
     htw.Flush();
}
htw.Close();

I need to write the loop through each of the tables and write it to the StringBuilder object. Is there any way of doing it without writing it to a file?

StringBuilder output = new StringBuilder();
foreach (Table table in tables)
{
StringWriter sw = new StringWriter(output);
HtmlTextWriter htw = new HtmlTextWriter(sw);
table.RenderControl(htw);
}

Select allOpen in new window

Is there a maximum value that a StringBuilder Object can hold, i get an Out of Memory error.Appreciate all help.

capacity of a StringBuilder class is 4GB.

The file i am trying to build through the Stringbuilder object is  2MB file, it should work alright?

Yes, it should, unless something bad in your loop

The code in the loop is pasted above.Please advise
