相同的退货类型?数据集& SqlDataReader的 [英] same return types ? DataSet & SqlDataReader
问题描述
这不可能吗?
公共DataSet getDimensions()
{
}
public SqlDataReader getDimensions()
{
}
我在编译时收到此错误:" ;类''ProductFamily''已经定义了一个名为''getDimensions'的成员名为''getDimensions'',参数类型相同
- 对我来说似乎不对 -
Hi, is this not possible?
public DataSet getDimensions()
{
}
public SqlDataReader getDimensions()
{
}
I get this error on compile: "Class ''ProductFamily'' already defines a
member called ''getDimensions'' with the same parameter types"
-- Doesnt seem right to me --

为什么不呢?在这种情况下你会期望被叫哪个:
对象o = getDimensions();
甚至只是
< br $>
getDimensions();
?

Why not? Which would you expect to be called in this case:
object o = getDimensions();
or even just
getDimensions();
?

我的印象是我可以在返回类型上超载
DataSet ds = getDimensions()
SqlDataReader dr = getDimensions()
I was under the impression that I could overload on return type
DataSet ds = getDimensions()
SqlDataReader dr = getDimensions()

不,你不能。
