通常的方法是进行一次重载,其中包含您可能需要的所有信息,并从其他方法调用,传递在
参数中。例如:
公共对象LookupItem(对象键,对象defaultValue)
{
...执行查找.. 。
}
//与LookupItem(key,defaultValue)相同,但默认值为
// null
公共对象LookupItem(对象键)
{
返回LookupItem(键,null);
}

The normal way is to make one overload which has all the information
you could possibly need, and call it from other methods, passing in
parameters. For instance:
public object LookupItem (object key, object defaultValue)
{
... do the lookup ...
}
// Same as LookupItem (key, defaultValue) but with a default value of
// null
public object LookupItem (object key)
{
return LookupItem (key, null);
}

Jon,
非常感谢。如果我想
将不同的类型传递给main方法,这将如何工作? Int16 vs
双倍?我是否必须将主方法设为对象
并根据需要进行投射?
干杯,
Paul

Jon,
Thank you much. How would this work if I wanted
to pass different types to the main method? Int16 vs
Double? Do I have to make the main method an Object
and cast as needed?
Cheers,
Paul

通常的方法是使一个重载具有你可能需要的所有信息
,并从其他方法调用它,传递在
参数中。例如:
公共对象LookupItem(对象键,对象defaultValue)
{
...执行查找.. 。
}
//与LookupItem(key,defaultValue)相同,但默认值为
// null

只要类型不同,你可以拥有与你想要的
相同方法的重载次数,即使参数数量相同,每个
。

As long as the types are different, you can have as many overloads of the
same method you want, even though the number of parameters are the same for
each.
