Question

I have 2 columns "PriceList" and "Group" in a DataTable.

PriceList contains, List1, List2, List3

Group contains, Group1, Group2, Group 3

var checkValues1 = new string[] { "List1", "List2" };

var checkValues2 = new string[] { "Group" };

This works

                dt.AsEnumerable().ToList().ForEach(x =>
                {
                    if (checkValues1.Contains(x["PriceList"]))
                    {
                        newDT.ImportRow(x); //Copy
                        DT.Rows.Remove(x); //Remove
                    }
                });

But I cant get this to work

                dt.AsEnumerable().ToList().ForEach(x =>
                {
                    if (checkValues2.Contains(x["Group"]))
                    {
                        newDT.ImportRow(x); //Copy
                        DT.Rows.Remove(x); //Remove
                    }
                });

Seems it need to be an exact match so it will only work for when group names is exactly "Group", I want it to match substrings also so "Group" would match Group1, Group2, Group 3. Is there anyway to do this?

Answer 1

For this you can use starts with function. below is example.

dt.AsEnumerable().ToList().ForEach(x =>
{
if (checkValues2.Any(t => t.StartsWith((x["Group"])))) 
{
newDT.ImportRow(x); //Copy
DT.Rows.Remove(x); //Remove
}
});
