when I set a dataview with a Rowfilter, can I find out somehow what is the filtered data?

my table:

1  mary
2 michael
3 hans
4 georg

my filter:

dataview.Rowfilter = " Name = ' michael ' ";

How can I retrieve the other 3 names without using the Rowfilter again like this:

dataview.Rowfilter = " Name <> 'michael';

HOpe the question is clear :)

You can ..... Loop through the rows in dataview.Table and pick out the ones that aren't in your filtered dataview.


Create a second dataview and create the opposite filter on that instead.

ah bad I told you crap...
requirements have changed actually again:

I want to enumerate through the dataview to get the each value in every row in the filtered dataview.

foreach (DataRowView row in dataview)
    row.value doesnt work
    row.Row[3]. doesnt work // I want to get the value in the 4th column of the actual row of my dataview

How can I enumerate through all Rows of the dataview and get a value of each row in a certain column?
I have to compare the one value in a dataview`s [row,column] with the value of a datareader...

I also tried this:

foreach (DataRowCollection row in dataview.Table.Rows)
    row. // no value or cell I get :/

for (int j = 0; i < dataview.Count; i++)
                          var articlenumber = dataview[j].Row[3].ToString();

found a sample in vb and changed it to c#, pretty stupid that there is no Row.Value or Cell.Value as someone could expect it.

foreach (DataRowView row in dataview)
  row[3]          <--------- thats the value in the 4th column

In your above sample, it'll be best if you don't mix up i and j......
