A correct way to write C# aka order convention of writing a C# class.

Order Convention Writng C# Class.cs

public class MyClass
{
    // Nested classes, structs, enums
    public class PublicNestedClass { }
    public struct PublicNestedStruct { }
    public enum PublicNestedEnum { A, B, C }

    private class PrivateNestedClass {  }
    private struct PrivateNestedStruct { }
    private enum PrivateNestedEnum { A, B, C }

    // Public static fields
    public static int PublicStaticField;

    // Protected static fields
    protected static int ProtectedStaticField;

    // Private static fields
    private static int PrivateStaticField;

    // Public properties abstract
    public abstract int PublicPropertyAbstract { get; set; }
    
    // Public properties virtual
    public virtual int PublicPropertyVirtual { get; set; }
    
    // Public properties override
    public override int PublicPropertyVirtual { get; set; }
    
    // Public properties
    public int PublicProperty { get; set; }

    // Protected properties
    protected int ProtectedProperty { get; set; }

    // Private properties
    private int PrivateProperty { get; set; }
    
    // Public instance const fields
    public const int PublicInstanceConstantField = 2023;
    
    // Public instance fields
    public int PublicInstanceField; // This should be illegal to write. Use private field instead.

    // Protected instance fields
    protected int ProtectedInstanceField;
    
    // Private instance const fields
    private const int _privateInstanceConstantField = 2023;

    // Private instance readonly fields
    private readonly int _privateInstanceReadOnlyField;

    // Private instance fields
    private int _privateInstanceField;

    // Public methods
    public void PublicMethod() { }

    // Protected methods
    protected void ProtectedMethod() { }

    // Private methods
    private void PrivateMethod() { }
}
