linq query in datatable c# code example

Example: c# datatable to linq

//You can't query against the DataTable's Rows collection, since 
//DataRowCollection doesn't implement IEnumerable<T>. 
//You need to use the AsEnumerable() extension for DataTable

var results = from myRow in myDataTable.AsEnumerable()
where myRow.Field<int>("RowNo") == 1
select myRow;


//AsEnumerable() returns IEnumerable<DataRow>. 
//If you need to convert IEnumerable<DataRow> to a DataTable,
//use the CopyToDataTable()
