I am trying to modify the value of a variable in the Command Window
(immediate mode) but I am getting an error.

Here is the code snippet:

U_Appr_InfoDS.U_APPR_INFODataTable dt =
da.GetAllAppraiserInfo(this.LoanNumber);
if (dt.Rows.Count > 0)        //My breakpoint is set here...

Here are the contents of the Command Window:

        dt.Rows.Count=1
        error: cannot assign '1' into 'dt.Rows.Count'

Can anyone give some insight to this problem or recommend a solution?

TIA

Luke

You do not offer enough information for anyone to know for sure, since y=
ou =

didn't include anything that would tell us for sure what the type of "dt=
" =

is, what type its Rows property is, or how the Count property is to be =

used.

However, if it's anything at all like other classes, the Count property =
is =

read-only and you cannot assign anything to it. If you want to change t=
he =

number of elements in the Rows collection, you need to do so by adding o=
r =

removing items. It's certainly possible to design a class that would do=
=

that for you when you assign a value to the Count property, but it would=
=

be a bad idea and I hope there aren't any .NET classes that do that.
