Question

It’s very easy I have the following Enum

Public Enum TCheckStatus
        Checked
        NotChecked
        Indeterminate 
    End Enum

I want to get the Index of the given name found in the enum, what’s the best way?!!

For Example:

Suppose I have “NotChecked” string , I want the output to be 1

You are looking for Enum.GetNames. It retrieves an array of the names of the constants in a specified enumeration.

Dim notCheckedStatus  = DirectCast([Enum].Parse(GetType(TCheckStatus), "NotChecked"), TCheckStatus)
Dim allStatusNames    = [Enum].GetNames(GetType(TCheckStatus))
Dim indexOfNotChecked = Array.IndexOf(AllStatusNames, "NotChecked") '=1'

1. line: parses a string variable to an enum-value
2. line: returns all enum-values of a given enum-type as Array
3. line: returns the index of a given enum-value in that Array

Of course to solve your question you only need this:

Array.IndexOf([Enum].GetNames(GetType(TCheckStatus)), "NotChecked")
