Split a DataTable into 2 or more DataTables based on Column value

Question

I have a DataTable called \"DTHead\" which has the following records,

 MIVID      Quantity         Value
------     ----------       --------
   1                    


        

Answer 1

Use LINQ to DataTable to group the first column by GroupBy, and use method CopyToDataTable to copy list of rows to DataTable

 List<DataTable> result = DTHead.AsEnumerable()
            .GroupBy(row => row.Field<int>("MIVID"))
            .Select(g => g.CopyToDataTable())
            .ToList();

Then you can get the result as a list of DataTables as you expected.

Answer 2

DataTable tbl = new DataTable("Data").AsEnumerable()
    .Where(r => r.Field<int>("ParentId") == 1) // ParentId == 1
    .Where(r => r.Field<int>("Id") > 3) // Id > 3
    .Where(r => r.Field<string>("Name").Contains("L")) // Name contains L
    .OrderBy(r => r.Field<int>("Id")) // Order by Id
    .CopyToDataTable();
