Question

I have

xmlDoc.DataSet.Tables["<tablename>"].Columns

I want to loop through those columns via DataColumn, for say this xmlDoc has 10 entries and 5 are null, then the loop should happen for the non-null entries only.

Any thoughts?

Answer 1

for (int i = 0; i < ds.Tables[0].Columns.Count; i++ )
{
    DataColumn col = ds.Tables[0].Columns[i] != null ? ds.Tables[0].Columns[i] : "<some default value>";
    if (col != "<some default value>")
                    // do something
}
