Hi,
A datatable has several fields, i.e. field1, field2, field3, field9, field10, field88...

string strData = "field1, field2, field3, ...";

Question:

So the datatable ends up with the following columns:
field9, field10, field88...

HOw is the above done in C# please?

Thanks

Hi,

do you want to remove this columns from database table or from DataTable object?

in first case you have to use SMO:
http://msdn.microsoft.com/en-us/library/ms204453.aspx[^]

in second case just split this string into array and loop through this array :

C#

DataTable t = ...
foreach(string col in cols)
{
   t.Columns.Remove(col);
}

cols variable represents string array of column names
