下边资料是关于C#如何定义与类或结构之间的转换的代码。

using System;

struct RomanNumeral

}
static public implicit operator RomanNumeral(int value)
{

}
static public implicit operator string(RomanNumeral roman)
{
return("Conversion not yet implemented");
}
private int value;
}

class Test
{
static public void Main()
{
RomanNumeral numeral;

numeral = 10;

Console.WriteLine((int)numeral);

Console.WriteLine(numeral);

short s = (short)numeral;

Console.WriteLine(s);
}
}
