Convert Comma Separated Value to Dictionary

Question

I'm trying to convert comma separated string to Dictionary

string text = "abc,xyz,pqr";

Output should be Dictionary<string, uint> with key as string from text & value as number starting from 0.

I tried below but it gives error:

text.Split(new[] {','}, StringSplitOptions.RemoveEmptyEntries).ToDictionary(split => split[0], 0))`

I'm also not sure how to give incremental value so I tried with constant hard coded value for all keys in dictionary as shown above but its giving error too.

Any help with either constant value for all keys or with incremental value using linq is much helpful!!

Answer 1

There are overloads of Select() which pass an index:

var dict = text.Split(new[] {','}, StringSplitOptions.RemoveEmptyEntries)
    .Select((str, idx) => new { str, idx })
    .ToDictionary(x => x.str, x => x.idx);
