I am unable to understand why this use of Substring does not work

[intrader]

Looking at the watch window, I have
----------------watch window-----------------------
ix 6 int
tStr "hyphen, and )(*" string

tStr.Substring(0,ix) error:'tStr.Substring' does not exist
---------------------------------------------------
I have no errors in the compile, and the following works:

string s="1234567890";
s=s.Substring(0,6)
----------------watch window-----------------------
s.Substring(0,6) "123456"
---------------------------------------------------

Thanks

I think I figured out. It appears that the IDE is paying attention to
the generated code.

The full expression I have is

tStr=tStr.Subsring(0,ix) + tStr(ix+1, tStr.Length-1);

which causes the index to be out of the string.

The expression should be

tStr=tStr.Subsring(0,ix) + tStr(ix+1, tStr.Length-ix-1);

Thanks for anyone looking at this.

That's why I coldn't see anything wrong with the code you posted... :)
