DataTable distinct(DataTable dtSource, DataColumn dcolDistinct, String
strNewTable)
{
String strCol = dcolDistinct.Caption;
// defining the new table here, in which only 1 col will be present
// The column will be primary key, hence no duplicaes will be allowed
DataTable dt = new DataTable(strNewTable);
dt.Columns.Add(new DataColumn(strCol, dcolDistinct.DataType, ""));
dt.PrimaryKey = new DataColumn[]{dt.Columns[0]};
// array to store values, length = 1, since distict runs on 1 col
Object[] temp = new Object[1];
Console.WriteLine("host table has {0} rows", dtSource.Rows.Count);
foreach(DataRow drw in dtSource.Rows)
{
temp[0] = drw[dcolDistinct];
dt.LoadDataRow(temp, true);
}
return dt;
}
private void test()
{
// pass table from which you want to select distinct values -
OrderDetails here
// pass column, which you want to make distinct - Product ID
// the name of the new table
// the distinct function returns a new datatable containing distinct
rows of a given column
DataTable newDT = distinct(dataSet11.Tables["OrderDetails"],
dataSet11.Tables["OrderDetails"].Columns["ProductID"],
"myTable");
Console.WriteLine("destination table has {0} rows", newDT.Rows.Count);
foreach(DataRow drw in newDT.Rows)
{
Console.WriteLine(drw[0]);
}
}
Paste the above code in your class & call function test(). Change table name/column
name in above case
Remove Console.writeline, after you feel, it gives you the output
Do post your reply, if this works out for you
