如何引用重构的类?

[fitel]

下面是一个数据库访问的类，其中RunProc被多次重写，如何引用这个:
public string RunProc(string procName, SqlParameter[] prams)
（运行存储过程返回字符串）这个？

哪位兄弟能够说一下，重构有什么优点或者说用途，详细点。马上给分。

[wanna51]

如果存储过程没有参数
string ret = RunProc(procName, (SqlParameter[])null);
如果有参数
string ret = RunProc(procName, new SqlParameter[]{par1,par2});

优点就是一个方法提供了多种参数使用。

这种行为叫 重载。。不叫重构

自己UP

直接引用，有什么问题吗？参数不同
