通过控制台界面访问编译器时包含库

Question

在这个例子的启发下,我决定扩展Factorial类.

using System;
using System.Numerics;

namespace Functions
{
    public class Factorial
    {
        public static BigInteger CalcRecursively(int number)
        {
            if (number > 1)
                return (BigInteger)number * CalcRecursively(number - 1);
            if (number <= 1)
                return 1;

            return 0;
        }

        public static BigInteger Calc(int number)
        {
            BigInteger rValue=1;

            for (int i = 0; i < number; i++)
            {
                rValue = rValue * (BigInteger)(number - i);                
            }

            return rValue;

        }      
    }
}

我使用过System.Numerics,默认情况下不包含它.因此,命令
csc /target:library /out:Functions.dll Factorial.cs DigitCounter.cs输出:

好.我错过了一个装配参考.我想"它一定很简单.整个系统应该是两个System.Numerics.dll文件 - 我需要的是添加到命令/链接:[System.Numerics.dll的x86版本的路径]".搜索结果冻结了我的灵魂:

正如你所看到的(或不是),有比我预测的更多的文件!而且,它们的大小和内容不同.我应该包括哪一个？为什么有五个文件,虽然只有两个存在点？/ link:命令是否正确？或许我的思维轨迹完全错了？

我一般都发现使用

/r:System.Numerics.dll

让编译器只在GAC中找到程序集,这通常是你想要的方式.(当然,前几天当我需要System.Numerics用于控制台应用程序时,它很好......)
