Hello experts:

Can someone please tell me why the code snippet below does not work.
The loop works and it populates RecContent just fine
but LDAcctNo is not populated

for (intCounter = 0; intCounter <= intLastElement; intCounter++)
{
RecContent = LoanDetArray.GetValue (intCounter).ToString();
LDAcctNo = RecContent.ToCharArray(0,20).ToString();
}
                                          
Thanks

If I look at your code you are filling RecContent in a loop
you must assign LDAcctNo after you have finished de loop

for (intCounter = 0; intCounter <= intLastElement; intCounter++)
{
RecContent = LoanDetArray.GetValue (intCounter).ToString();
}

LDAcctNo = RecContent.ToCharArray(0,20).ToString();

Everytime the RecContent is populated I need to
get the LDAcctNo also
 
How can I make the LDAcctNo = RecContent.ToCharArray(0,20).ToString();
part of the loop?

I think i mist the point,
I just tried your code,

do you get a exception ???

you do not check the length of RecCont.

change the code to

                LDAcctNo = RecContent.ToCharArray(0, Math.Min(20,RecContent.Length)).ToString();

I hope that this is your problem

what are the types of LDAcctNo and RecContent ??

I don't get an exception
but when I step thru the code
RecContent gets populated and the 1st record has accountnumber 00000000000000000001
but LDAcctNo does not.
When I put the cursor on top of it , it says "System.Char[]". I was expecting to see 00000000000000000001

I get this error with my original code or your code.  

Both are strings

I get the same error

Why do you use  RecContent.ToCharArray(0,20).ToString();
The ToString is not implemeted to ToCharArray and gives back the type

if you try to copy a substring use

LDAcctNo = RecContent.Substring(0, 20);
