在未知对象上从BaseEntity调用通用方法

Question

this is what I do if I know the type;

TypeA.Get<TypeA>(Id).Delete();

and what I am trying to do is this;

object ObjectA;

(BaseEntity<typeof(ObjectA)>).Get<(BaseEntity<typeof(ObjectA)>)>(Id).Delete();

which didn't work, any idea how to do this properly?

Answer 1

You can either:

• use reflection to call both Get and Delete methods, or:
• use reflection to call Get and dynamic to invoke Delete

Since you're giving up static typing either way, I'd go with the 2nd option for simplicity.

var typeA = objectA.GetType();
var fEntityType = typeof(FEntity<>).MakeGenericType(typeA);

var getMethod = fEntityType.GetMethod("Get").MakeGenericMethod(typeA);

dynamic result = getMethod.Invoke(null, new object[]{ Id });

result.Delete();
