convert List<T> to F# seq
f#

hello, group

I am newbie to F#. Is there way to convert C# List<T> to F# seq? I need to convert the element in List<T> to different types and insert into F# seq.

for example

C# has the type: public class T { int Type; }

F# has types: Type0, Type1, Type2, they all have a member which can hold the instance of T.

if T.Type==0 then insert Type0 object into F# seq,

if T.Type==1 then insert Type1 object into F# seq, etc.

Thanks for the help.

.

Here's one way. I created a class T and added a static method to return a populated List<T> for testing purposes.

let tList = T.getList()

let seq0 = seq { for x in tList do if x.Type = 0 then yield x }
let seq1 = seq { for x in tList do if x.Type = 1 then yield x }
let seq2 = seq { for x in tList do if x.Type = 2 then yield x }
