c# - How do I output the results of a LINQ command to a text file? -

 var arrresults = array1.join(array2, x => x.id, x => x.id, (first, second) => new             {                 idrecord = first.id,                 count1 = first.count,                 count2 = second.count,             })             .orderby(item => item.idrecord).toarray();               // bind & display results in datagrid             datagridview1.datasource = arrresults; 

my above code want to, , shows results in datagrid control. now, i'd export results text file, c:\output.txt, instead. how do this?

my previous attempts involve getting errors "cannot convert 'string' system.collections.generic.ienumerable".

first convert results strings:

var lines = arrresults.select(record =>      record.id + " " + record.count1 + " " + record.count2);//todo fix formatting 

then write them file.

file.writealllines("file.txt", lines);
