I have A
class:
public abstract class A
{
}
And then I have B
class that derives from it:
public sealed class B : A
{
public void SomeMethod()
{
var method = this.GetType().GetMethod("AddText");
}
private void AddText(string text)
{
...
}
}
Why is GetMethod
returning null?
In the real sense it has no meaning or full form. It was developed by Dennis Ritchie and Ken Thompson at AT&T bell Lab. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C++ which was invented by Dr.
" " C is a computer programming language. That means that you can use C to create lists of instructions for a computer to follow. C is one of thousands of programming languages currently in use.
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
var methodInfo = this.GetType().GetMethod("AddText", BindingFlags.Instance | BindingFlags.NonPublic, null, new Type[] { typeof(string) }, null);
Your method has a parameter, you need to use the overload that accepts a type array for the parameter types and the binding flags.
In .net Method signatures are based on their name, their return type, and their parameters.
So if your method has parameters you have to tell Reflection what parameter types it has via a Type[].
By default, Reflection will only search for public methods.
You need to pass BindingFlags.Instance | BindingFlags.NonPublic
