In C# I have following methods defined in given class (non static):
int MyMethod(ScriptEngine script, int a, int b) {
return a + b;
}
void MyMethod2(ScriptEngine script, string c) {
// do something with c
}
I want to create wrapping lambda / Action / Delegate / MethodInfo (all are accepted by script engine) that automatically passes ScriptEngine
and this
from given, predefined variables.
So far I've experimenting with:
// With overloads up to 16 template parameters
Action<T1> Wrap<T1>(Action<ScriptEngine, T1> func, ScriptEngine script) {
return (Action<T1>) ((t1) => func(script, t1));
}
But when called on MyMethod2 I've got The type arguments for method … cannot be inferred from the usage. Try specifying the type arguments explicitly
Is there any way I can create such wrapper automatically (or semi-automatically)?
Update
There is dedicated abstract method void RegisterAll(ScriptEngine script)
that can register required members of given subclass
Update2
Example of what I am trying to achieve (requested in comment)
class ScriptEngine { // Stub to have complete example, actual implementation is defined elsewhere
void RegisterApi(string name, MethodInfo methodInfo) { }
void RegisterApi(string name, Delegate delegateSelf) { }
}
class Api {
int MyMethod(ScriptEngine script, int a, int b) {
return a + b;
}
void MyMethod2(ScriptEngine script, string c) {
// do something with c
}
void RegisterAll(ScriptEngine script) {
script.RegisterApi(nameof(MyMethod), (Delegate)Wrap<string>(MyMethod, script)); // Is there any way to shorten this up (not providing MyMethod twice, not providing template arguments?)
}
}
