怎么样在c#调用dll中参数为ref object 类型的函数呀？

[wsmt]

请问我需要怎样去放入这样一个参数呀？

如 f1(ref object v1,ref object v2){}

v1,v2我该定义一个什么类型的呀？？？

示例
// cs_ref.cs
using System;
public class MyClass
{
public static void TestRef(ref char i)
{
// The value of i will be changed in the calling method
i = 'b';
}

public static void TestNoRef(char i)
{
// The value of i will be unchanged in the calling method
i = 'c';
}

// This method passes a variable as a ref parameter; the value of the
// variable is changed after control passes back to this method.
// The same variable is passed as a value parameter; the value of the
// variable is unchanged after control is passed back to this method.
public static void Main()
{

char i = 'a'; // variable must be initialized
TestRef(ref i); // the arg must be passed as ref
Console.WriteLine(i);
TestNoRef(i);
Console.WriteLine(i);
}
}
输出
b
b
