❔ error CS1525: Unexpected symbol `String'

using System; public String DuplicateCount(string input) {
foreach (char a in input) { int i = a.Count; if (i > 1){ Console.WriteLine($"{a}:{i}");} }
} DuplicateCount("indivisibilities"); why doesn't this work?

a.Count is invalid

yes, but that's not the main problem here somehow String on line 3 isn't recognised

leowest•2y ago

what is line 3

supriseXOP•2y ago

public String DuplicateCount(string input)

if you were using visual studio, it would have pointed those out for u what IDE are you using

supriseXOP•2y ago

online, vs code is being weird, doesn't wanna run.

ah well I suggest u use visual studio community instead its really helpful while learning so what are you trying to do here

    foreach (char a in input)
    {
        int i = a.Count;
        if (i > 1){
        Console.WriteLine($"{a}:{i}");}
    }

    foreach (char a in input)
    {
        int i = a.Count;
        if (i > 1){
        Console.WriteLine($"{a}:{i}");}
    }

are u trying to skip the first letter?

ah yeah silly me should have read the method name so yeah what you want to do is, you might want to have a Dictionary to hold the char and count as you iterate in your loop and add to the dictionary and then loop thru the dictionary where your Value is bigger than one a is a char so you can't use Count like that which is why its invalid
