        public void con(long bin)
        {
            long temp = bin;
            long deci ;
            while (bin!= 0)
            {
                long j = 1;
                long remainder = bin % 10;
                deci = deci + remainder * j;
                j = j * 2;
                bin = bin / 10;
            }
            
            Console.WriteLine("Decimal value is {0}",deci);
            
           
        }
        
    }
}

推荐答案

请将deci变量初始化如下。

long deci = 0;

Please initialize the deci variable as below.
long deci=0;

long temp = bin;
        long deci=0;
        while (bin != 0)
        {
            long j = 1;
            long remainder = bin % 10;
            deci = deci + remainder * j;
            j = j * 2;
            bin = bin / 10;
        }
