通过反射将方法动态分配给委托(delegate)实例时,我陷入了困境。以下是我面临的情况的示例场景。
class Program
{
static void Main(string[] args)
{
new DynamicDelegateTest().Test();
}
}
public class DynamicDelegateTest
{
public void Test()
{
//This is what i target to do through reflection
ABC objABC1 = new ABC();
objABC1.Proc = Debugger;
objABC1.Test("Helloz");
//Implementing the same code through reflection
ABC objABC = new ABC();
MethodInfo MIDebugger = GetType().GetMethod("Debugger", BindingFlags.NonPublic | BindingFlags.Instance);
FieldInfo MyProc = objABC.GetType().GetField("Proc", BindingFlags.Public | BindingFlags.Instance);
//This is the point where I got stuck up
MyProc.SetValue(objABC, MIDebugger);
objABC.Test("QWERTY");
}
void Debugger(object Tests)
{
Console.WriteLine(Tests);
}
}
public class ABC
{
public delegate void Delg(object P1);
public Delg Proc;
public void Test(object Tst)
{
if (Proc != null) Proc(Tst);
}
}
请帮忙。
最佳答案
您需要使用 Delegate.CreateDelegate
来获取委托(delegate)实例,而不是方法信息。对于非静态方法,这还包括目标实例。在这种情况下:
object del = Delegate.CreateDelegate(MyProc.FieldType, this, MIDebugger);
MyProc.SetValue(objABC, del);
