I am writing a DataTable to a file using a stringbuilder.
The Format of the date in the table is like this: '12/20/04'
But after I write it to the file it ads the time: '12/20/04 12:00:00 AM'
My code looks like this
for(int curRow = 0; curRow < dt1.Rows.Count; curRow++)
{
for(int curCol = 0; curCol < dt1.Columns.Cou nt; curCol++)
{
sb = sb.Append(dt1.R ows[curRow][curCol].ToString().Tri m()).Append(del im);
}
sb.Append(Envir onment.NewLine) ;
}
f.WriteLine(sb. ToString());
f.Close();
I know there is something like .toshortdate, but I don't know where to put it.

Hi,
object dateObj=dt1.Row s[curRow][curCol]; // if its a DateTime field
if( dateObj!=DBNull .Value ) {
sb.Append(((Dat eTime) dateObj).ToShor tDateString());
// or
// sb.AppendFormat ("dd/MM/yy", dateObj); // if i'm not wrong
}

This did not work when used in conjunction with a stringbuilder.
Error 'No overload for method 'ToString' takes '1' Arguments.
See thread from Marcin.
Thanks

Thank You
This way: sb.Append(((Dat eTime) dateObj).ToShor tDateString());
Worked
This way: sb.AppendFormat ("dd/MM/yy", dateObj);
Did not, it actually added the literal string 'dd/MM/yy' to the file. I also
tried "dd-MM-yy" and "d".
I'll use the first one, it works just fine.
Thank you.

The string builder is not the problem. It's just that Derek forget that
while we know that the object returned from dt1.Rows[ curRow][ curCol] is
actually a DateTime, it's really just an Object.
object cell = dt1.Rows[ curRow][ curCol];
if ( dt1.Columns[curCol].DataType == typeof( DateTime) )
sb.Append( ((DateTime) obj).ToString( "d").Trim( ));
else
sb.Append( obj.ToString( ).Trim( ));
sb.Append( delim);

Hi,
Can a StringBuilder buffer be cleared? I'm confused. It is supposed that the StringBuilder class, can deal with all the memory allocation and deallocation needed for normal string operations (concatenations, replacements, etc.), because the String class just creates and destroys instances at an object level. I can't find a method to clear a StringBuilder object's buffer for reusing it (the idea is to avoid object...

I want to use the "replace" in the string builder class. I've imported the "system.text.stringbuilder" class into my project. However, I don't see the method call for "replace(oldchar,newchar,startindx,numofchars)" format.
It does not show up in intellisense.
What am I doing wrong. See below:

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
