c# - Linq Expression for DataTable to URLEncoding only Unicode characters -

need url encode each character if unicode character or range of unicode characters leave non-unicode characters alone if have asci-ii representations using linq expressions link.

also i'm trying system detect if unicode character exists first before attempting urlencode it.

     datatable dt = new datatable();      dt.tablename = "testcase1";      dt.columns.add("label");      dt.columns.add("value");      for(int i=0; i<10; i++)      {          datarow row = dt.newrow();          row["label"] = "test ®±¶ me ™.";          row["value"] = i;          dt.rows.add(row);      }       // use linq expression url encode label field     var rowstoupdate = dt.asenumerable().where(a => a.field<string>("label").length > 0);      foreach (var row in rowstoupdate)     {         row.setfield("label", uri.escapeuristring(row[0].tostring()));     }      foreach (datarow row in dt.rows)     {         console.writeline(row["label"].tostring());         console.writeline(row["value"].tostring());     } 

the main reason want if url encode entire string makes spaces plus symbols , formatting horrendous when use in asp.net label or text box.

also in asp.net i'm using httpcontext.current.server.urlencode function encode value. in console app example above i'm using uri.escapeuristring function.
