Get and Set Private Properties using Reflection in C#

It's frustrating when you're using an API and some properties you requuire are set as private. This certainly was the case when attempting to resume a video using the YouTube V3 API the other day.

Here is a code snippet on how to set private properties using Reflection.

Code Snippet

1. private static void SetPrivateProperty<T>(Object obj, string propertyName, object value)
2. {
3. var propertyInfo = typeof(T).GetProperty(propertyName, System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
4. if (propertyInfo == null) return;
5. propertyInfo.SetValue(obj, value, null);
6. }
7. private static object GetPrivateProperty<T>(Object obj, string propertyName)
8. {
9. if (obj == null) return null;
10. var propertyInfo = typeof(T).GetProperty(propertyName, System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
11. return propertyInfo == null ? null : propertyInfo.GetValue(obj, null);
12. }

MsgBox - A Better Winforms MessageBox in C#

Introduction

MsgBox is an enhanced solution to the in-built MessageBox class. It's designed so that the styles, features and behaviour mimic the in-built control with added features.
MsgBox allows a better Messagebox experience by allowing the following features:
- Do not display this message again
- Custom font styles and font colors
- Scrollbars for text which is too long

Using the code

MsgBox is used like a standard MessageBox object. There is a different return object which encapsulates the original DialogResult. This handles extra information which as whether the user clicked 'Do no display this message again'.
