c# - Get the index of each item in a loop -

i have datatable , doing operations on take result this:

var result = row in dtgraph.asenumerable()              group row row.field<string>("campaign") grp              select new              {                  campaign = grp.key,                  count = grp.count(),                  sl = grp.sum(s => s.field<decimal>("inb.servicelevel"))              }; 

i want loop on result

i tried these 2 ways:

first

for (int i=0;i< result.count(); i++){ { } 

but couldn't type result[i].count

second

foreach (var item in result) {  } 

your linq expression returns ienumerable, cannot accessed through indexer. why result[i] in first attempt not work.

the fix simple: convert ienumerable list:

var result = (from ... select new { ... }).tolist();
