请教如何将C程序转换C#程序
程序代码：#include <stdio.h>

#include <stdlib.h>
#include <time.h>
#define SUM 20 //总共的染色体数量
#define MAXloop 1200 //最大循环次数
#define error 0.01 //若两次最优值之差小于此数则认为结果没有改变
#define crossp 0.7 //交叉概率
#define mp 0.04 //变异概率
struct gen //定义染色体结构
{
int info;
float suitability;
};
struct gen gen_group[SUM];//定义一个含有20个染色体的组
struct gen gen_new[SUM];
struct gen gen_result; //记录最优的染色体

struct log //形成链表，记录每次循环所产生的最优的适应度
