简单案例:
public class MyClass
{
public Action<double> MyAction;
}
public class AnotherClass
{
public void MyAction(double value)
{
// ...
}
}
当我通过反射获得AnotherClass.MyAction(..)
方法和MyClass.MyAction
委托时,我最终得到了一对MethodInfo / FieldInfo类,我无法将该方法连接到委托。此外,我从字符串中获取方法/委托名称,我无法访问没有反射的实例字段/方法。任何人都可以帮我解决这个问题,或者这种联系是否可行呢?

你应该特别注意Delegate.CreateDelegate
:
MethodInfo method = typeof(AnotherClass).GetMethod("MyAction");
FieldInfo field = typeof(MyClass).GetField("MyAction");
AnotherClass obj = // the object you want to bind to
Delegate action = Delegate.CreateDelegate(field.FieldType, obj, method);
MyClass obj2 = // the object you want to store the delegate in
field.SetValue(obj2, action);
