c#非泛型“***”不能与类型实参一起使用的错误

Question

    public class DynamicBuilder<T>
    {
        private static readonly MethodInfo getValueMethod;
        private Load<T> handler;//这行报错

            return builder;
        }        private delegate T Load(IDataRecord dataRecord);
    }

Answer 1

private delegate T Load(IDataRecord dataRecord);这里load也没有<T>呀
