from and select in c# .net? -


can please tell me how specify particular column in select statement given below:

var combinedrows = dt1 in dsresults.tables[0].asenumerable()                    join dt2 in dsresults.tables[1].asenumerable()                      on dt1.field<string>("methodname") equals dt2.field<string>("methodname")                    select new { dt1, dt2 };  datatable finaldt = new datatable("finaltable"); finaldt.columns.add(new datacolumn("sp", typeof(string))); finaldt.columns.add(new datacolumn("method", typeof(string))); finaldt.columns.add(new datacolumn("class", typeof(string))); finaldt.columns.add(new datacolumn("bllmethod", typeof(string))); datarow newrow = finaldt.newrow();            foreach (var row in combinedrows) {      datarow datarow = finaldt.newrow();     datarow.itemarray = row.dt1.itemarray;       finaldt.rows.add(datarow); }

if want specify columns want select, should try changing

combinedrows = dt1 in dsresults.tables[0].asenumerable() join dt2 in dsresults.tables[1].asenumerable() on dt1.field("methodname") equals dt2.field("methodname") select new { dt1, dt2 };

in 

combinedrows = dt1 in dsresults.tables[0].asenumerable() join dt2 in dsresults.tables[1].asenumerable() on dt1.field("methodname") equals dt2.field("methodname") select new  {      dt1.columnname;      dt2.columnname2;      dt2.columnname3;      etc. }

hope looking for.

you can have @ linq-cheatsheet
