I'm quite new to Linq. I have something like this:
dict = fullGatewayResponse.
Split(',').ToDictionary(key => key.Split('=')[0], value => value.Split('=')[1])
This works fine but for obvious reasons I don't want the split() method to be called twice. How can I do that ?
Thanks for all your responses :), but I can only choose one.
You can convert each item to an array before ToDictionary
by using Select
:
dict = fullGatewayResponse.Split(',')
.Select(item => item.Split('='))
.ToDictionary(keySelector: parts => parts[0],
elementSelector: parts => parts[1]);
dict = (from item in fullGatetayResponse.Split(',')
let pair = item.Split('=')
select pair).ToDictionary(x => x[0], x => x[1]);
or, if you want to keep the existence of the array hidden:
dict = (from item in fullGatetayResponse.Split(',')
let pair = item.Split('=')
select new{Key=pair[0],Value=pair[1]).ToDictionary(x=>x.Key,x=>x.Value);
Try this:
dict = fullGatewayResponse.Split(',')
.Select(y => y.Split('='))
.ToDictionary(y => y[0], x => x[1])
This will work but I don't think there is any point in saving a split operation
var dict = fullGatewayResponse.Split(',')
.Select(i=>i.Split('='))
.ToDictionary(key=>key[0],value=>value[1]);
