Hi,
C# Annoying string function or Am I doing Something wrong?
In VB6/VB.NET I can code like:
value = value.trim()
and it just work!
But in c#, I event put in the additional check I still get the error.
if (value.Length > 0 && value != string.Empty){
value = value.trim();
}
The error message:
startIndex cannot be larger than length of string.
Parameter name: startIndex at
System.String.I nternalSubStrin gWithChecks(Int 32 startIndex, Int32
length, Boolean fAlwaysCopy) ...
Please Help!
Thanks.

Hi Hitesh,
My code extract data from the mshtml.HTMLElem ent
string value;
mshtml.IHTMLDoc ument2 doc;
mshtml.IHTMLEle mentCollection tbls = (mshtml.IHTMLEl ementCollection )
((mshtml.IHTMLE lementCollectio n) doc.body.all).t ags("table");
mshtml.HTMLTabl e tbl = (mshtml.HTMLTab le) tbls.item(1,1);
mshtml.HTMLTabl eRow tblRow = (mshtml.HTMLTab leRow) tbl.rows.item(1 ,1);
if (tblRow.cells != null)
{
mshtml.IHTMLEle ment tblElement = (mshtml.IHTMLEl ement)
tblRow.Cells.it em(2,2);
value = tblElement.inne rText;
// Error Occur Here!
if (value.Length > 0 && value != string.Empty){
value = value.Trim();
}
}
I think the problem occur when the innerText is Empty and I am trying to
trim the value.

I don't think the problem is where you think it is.
Could you post a short but complete program which demonstrates the
problem?
See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.

Dear Jon and Hitesh
Thank your!
I have found the problem, it was due to the tblElement that I am
refering to does not exist.
It never occurr to me to think twice whether it could be something else.
Because when I don't put the Trim() statement in it work! (Without
Error/Warning).
That's why I thought it was having to do with the Trim() function.
Thanks again for your time!

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