5yAsked Jul 22, 2021, 5:44 AM3.7kVisual Basic .NET

why cannot i initialise a dictionary with values from enum. for example

enum cust {
OneTime
}

dictionary custs = new dictionary() {
{cust.OneTime, "some string values"}
}

getting argument is not assignable to type int error

any thoughts?

There are three ways to perform :

Dictionary keyValuePairs1 = new Dictionary
{
{ (int)Flat.O101, "O-105" }
};

Dictionary keyValuePairs2 = new Dictionary
{
{ Flat.O101, "O-105" }
};

Dictionary keyValuePairs3 = new Dictionary
{
{ Convert.ToInt32(Flat.O101), "O-105" }
};

1. dictionary custs = new dictionary<int, string>() {
2. {cust.OneTime, "some string values"}
3. }

You have to specify the type explictly as like below

Dictionary<Cust, string> custs = new Dictionary<Cust, string>()

Alterantively , you can type case of your enum in case you want to change the type.

dictionary custs = new dictionary() {

{(int)cust.OneTime, "some string values"}
}
