Question

I have a object called:

SqlCeDataReader rdr;

Because SqlCeDataReader does not have HasRows function, I wrote one:

if (!HasRows(rdr)) // Iterate to find number of rows
{
}

while (rdr.Read()) // Read the reader
{
}

The rdr.Read() does not return any result.

If I comment out the first iteration, It return result.

Thank you.

You can’t iterate twice – SqlCeDataReader “provides a way of reading a forward-only stream of data rows from a data source.” – MSDN.

But it does have a HasRows property – just use that?
