I have the following code whose purpose is to take 2 typed datasets (of type
DSAccounts )  & remove all elements of one from the other. and return what
is left.

However I am getting the error message "The given datarow is not in the
current DataRowCollection" when the "dtAll.tblAccounts.Rows.Remove(dr);"
line executes. I have debugged and found that the data to be deleted is
definitely present in the master dataset.

What am i doing wrong?? Please help!

private DSAccounts RemoveFromDS(DSAccounts dtAll, DSAccounts dtRemove ) {

try {

string account;

foreach (DSAccounts.tblAccountsRow dr in dtRemove.tblAccounts.Rows)  {

account = dr[0].ToString();

if (dtAll.tblAccounts.Rows.Contains(account))

       dtAll.tblAccounts.Rows.Remove(dr);

}

return dtAll;

}

catch (Exception e) {

throw e;

}

}
