如何通過未包含在數組中的值過濾DataTable？

Question

如果我有一個DataTable userwidget，它具有以下欄目：

PROCESS_ID，emp_num，widget_color

如何根據下列條件使用LINQ過濾此DataTable：

---

1- WHERE emp_num = ...

2-和process_id NOT IN (process)//process is an array of intgers

Answer 1

var filtered = (from row in tbl.AsEnumerable() 
       where row.Field<int>("emp_num")==yourNum 
       && !process.Contains(row.Field<int>("process_id")) 
       select row).CopyToDataTable(); 

Answer 2

使用，where <list>.Contains(<item>)

var lstprocessid = {1, 2, 3}; 
    var rows = 
     (from datatable in dtDetails.AsEnumerable() 
      where !lstprocessid.Contains(int.parse((datatable["process_id "]).ToString()) 
       && int.parse((datatable["emp_num"]).ToString())== myemp_num  
        select datatable).ToList<DataRow>();
