B= 2,
}

private void Form1_Load(object sender, EventArgs e)
{
Dictionary<string, int> dictionary = new Dictionary<string,int>();
foreach (int enumValue in Enum.GetValues(typeof(MyEnumType)))
{
dictionary.Add(Enum.GetName(typeof(MyEnumType), enumValue), enumValue);
}

comboBox1.DisplayMember = "Key";
comboBox1.ValueMember = "Value";

All you have done is copy the working solution from 7 years ago and put the code into a form load event. In what way do you think this is a solution?

You can find somewhat long but a very comprehensive answer in two of my articles:

Enumeration Types do not Enumerate! Working around .NET and Language Limitations[^],
Human-readable Enumeration Meta-data[^].
