Dynamic caller give error MissingMethodException: Method 'Clock.TEST' not found-CodePudding

Brief introduction: Currently developing a videogames/leraning project in unity whit c#, i have some issues and cant use system.windows.forms neither the system.therading, so i decide to make my own clock and have more control.

i want that this clock have a dynamic caller per tick, so when it ticks a method from another object is called, using system.reflection and many blogs and sites for reference i found how to make it call methods from the same object whit the unity invoke, i want this to call any method in the game, like the system.windows.forms, at this point i make this:

public object InvokeByName(string typeName, string methodName, object target)
{
    Type callType = Type.GetType(typeName);
    Binder defaultBinder = Type.DefaultBinder;
    return callType.InvokeMember(methodName, 
                BindingFlags.InvokeMethod | BindingFlags.Public, 
                defaultBinder, target , new object[] { });
}

public void Tick(string method, string methodName, object target)
{
    InvokeByName(method, methodName, target);
}


public void Set_Tick(string typeName, string methodName, object target)
{
    this.typeName = typeName;
    this.methodName = methodName;
    this.target = target;
}

public void TEST()
{
    Debug.Log("TEST");
}

the issue here is the method isnt capable of finding the method tick, when i set the tick to clock.Set_Tick("Clock", "TEST", clock);

this should execute the method Clock.TEST but for some reason it is incapable of finding the method, i try almost everything and also read similar cuestions in stack but they arent suited for this issue, ideas?

CodePudding user response：

You need to provide one more flag - BindingFlags.Instance to the invoke call:

return callType.InvokeMember(methodName,
            BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Instance,
            defaultBinder, target, new object[] { });

CodePudding user response：

In your call to InvokeMember you are not specifying that the method should search all members of the object instance. Add BindingFlags.Instance as an additional binding flag:

return callType.InvokeMember(methodName, 
   BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Instance, 
   defaultBinder, target , new object[] { }
);
