I'm trying to write an html file to disk via a StringBuilder and File.WriteLn(), but the file is written lacking a few lines, and is thus useless. My code is:
private void BuildAndWriteHTMLFile()
{
StringBuilder sb = new StringBuilder();
sb.Append("<!DOCTYPE html>");
sb.Append("<html lang=\"en\">");
sb.Append("<head>");
sb.Append("<meta charset=\"utf-8\">");
sb.Append("<title>Green Bay Packers 2013 Schedule (All times Central)</title>");
sb.Append("<script src=\"http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js\"></script> ");
sb.Append("<script src=\"http://maps.google.com/maps/api/js?sensor=false\"></script> ");
sb.Append("<script src=\"gomap.js\"></script> ");
sb.Append("<!--[if IE]>");
sb.Append("<script src=\"http://html5shiv.googlecode.com/svn/trunk/html5.js\"></script>");
sb.Append("<![endif]-->");
. . . // oodles on noodly code elided for lack of reason to leave it in
sb.Append("this.singleMarker = false;");
sb.Append("this.lockGeocode = false;");
sb.Append("this.markers = [];");
sb.Append("this.tmpMarkers = [];");
sb.Append("this.geoMarkers = [];");
sb.Append("},");
sb.Append("isVisible: function(latlng) {");
sb.Append("return this.map.getBounds().contains(latlng);");
sb.Append("}");
sb.Append("}");
sb.Append("})(jQuery);");
sb.Append("$(function() {");
sb.Append("$(\"#map\").goMap({ ");
sb.Append("latitude: 36.75, ");
sb.Append("longitude: -100, ");
sb.Append("maptype: 'ROADMAP',");
sb.Append("zoom: 5");
sb.Append("}); ");
sb.Append("$.goMap.createMarker({");
sb.Append("address: 'Green Bay, Wisconsin',");
sb.Append("title: 'Lambeau Field, Green Bay, WI',");
sb.Append("html: '<h1>Green Bay Packers Home Games</h1><p class=\"away\">Game 1, Week 1) Sunday Sept. 8 at SAN FRANCISCO 49ERS 3:25 p.m.</p><p>Game 2, Week 2) Sunday Sept. 15 WASHINGTON REDSKINS Noon</p><p class=\"away\">Game 3, Week 3) Sunday Sept. 22 at CINCINNATI BENGALS Noon</p><p>Game 4, Week 5) Sunday Oct. 6 DETROIT LIONS Noon</p><p class=\"away\">Game 5, Week 6) Sunday Oct. 13 at BALTIMORE RAVENS Noon</p><p>Game 6, Week 7) Sunday Oct. 20 CLEVELAND BROWNS 3:25 p.m.</p><p class=\"away\">Game 7, Week 8) Sunday Oct. 27 at MINNESOTA VIKINGS 7:30 p.m.</p><p>Game 8, Week 9) Monday Nov. 4 CHICAGO BEARS 7:40 p.m.</p><p>Game 9, Week 10) Sunday Nov. 10 PHILADELPHIA EAGLES Noon</p><p class=\"away\">Game 10, Week 11) Sunday Nov. 17 at NEW YORK GIANTS 7:30 p.m. (flex)</p><p>Game 11, Week 12) Sunday Nov. 24 MINNESOTA VIKINGS Noon (flex)</p><p class=\"away\">Game 12, Week 13) Thursday Nov. 28 at DETROIT LIONS 11:30 a.m. </p><p>Game 13, Week 14) Sunday Dec. 8 ATLANTA FALCONS 7:30 p.m. (flex)</p><p class=\"away\">Game 14, Week 15) Sunday Dec. 15 at DALLAS COWBOYS 3:25 p.m. (flex)</p><p>Game 15, Week 16) Sunday Dec. 22 PITTSBURGH STEELERS 3:25 p.m. (flex)</p><p class=\"away\">Game 16, Week 17) Sunday Dec. 29 at CHICAGO BEARS Noon (flex)</p><p class=\"away\">SUPER BOWL Sunday Feb. 2, 2014 vs ?</p>'");

string nameOfFile = string.Format(@"C:\misc\mapcode_{0}", GetFileNameDateTimeExtension());
if (!File.Exists(nameOfFile))
{
StreamWriter file = new StreamWriter(@nameOfFile);
file.WriteLine(sb.ToString());
urlOfGeneratedFile = string.Format("file:///{0}", nameOfFile);
webBrowser1.Url = new Uri(urlOfGeneratedFile);
}
}
The problem is that the file that is written is a truncated version of what's in the StringBuilder. It first truncated the last few lines that had been appended (with the written file ending on "NEW YORK G"); when I commented out the last createMarker section just prior to the closing script, body, and html tags, the file ended a little above that on "this.lockGeocode = false;this.markers = [];this.tmpMarkers = [];this.geoM"
It's as if the write to file is being done before all the lines have been written to the StringBuilder.
Do I need to call Flush, or a Sleep method, or what?
You are not closing/disposing of the StreamWriter, the writer has a internal buffer that is not written out till you close the stream. Wrap the writer in a using statment to automaticly close the file when done.
if (!File.Exists(nameOfFile))
{
using(StreamWriter file = new StreamWriter(@nameOfFile))
{
file.WriteLine(sb.ToString());
}
urlOfGeneratedFile = string.Format("file:///{0}", nameOfFile);
webBrowser1.Url = new Uri(urlOfGeneratedFile);
}
However, your code could be simplied to just not use a StreamWriter and instead just call File.WriteAllText
if (!File.Exists(nameOfFile))
{
File.WriteAllText(@nameOfFile,sb.ToString());
urlOfGeneratedFile = string.Format("file:///{0}", nameOfFile);
webBrowser1.Url = new Uri(urlOfGeneratedFile);
}
UPDATE: Actually, there will be a slight difference with File.WriteAllText, the file.WriteLine will add a extra newline at the end of the text, File.WriteAllText will not. If it is important to you that the newline is there add a sp.AppendLine(); before you call File.WriteAllText.
