阅读下面.net代码: struct Celsius { public Celsius(float temp) { this.temp=temp; } public static implicit operator Ceisius(float temp) { Celsius c; c=new Celsius(temp); return c; } public static implicit operator float(Ceisius c) { return ((((c.temp-32)/9)*5)); } public float temp; } class Temp1App { public static void main() { float t; t=98.6F; Console.Write("转化{0}为Celsius为",t); Console.WriteLine((Celsius)t); Console.WriteLine("t={0}",t); Console.ReadLine(); } } 请问最后的运行结果为( )
