C#debug.log没有在方法中显示正确的信息.(使用mono和unity)

我正在承担统一设计游戏的任务。我不是编程专家，但我在Ansi C中有很多知识。所以，如果我的代码像C#，请原谅我。

该方法运行良好，但由于一些奇怪的原因，Debug.Log(string.Format("",)显示：

pop_class index value 0 value = 0,
pop_class index value 1 value = 1,   

如果我只是在方法之外键入debug.log并使用相同的信息，那么它将显示i变量和pop_class[i]，所有内容都会正确显示<知道为什么会这样吗>这个程序很复杂，我不想在调试时与日志文件纠缠。

public int pop_generation() //debugger is currently not displaying vars correctly
{   
    int pop_increase = 1000000;
    int pop_counter = 0;//counts populations assigned by the 1000s
    int high_class_per = 10;
    int mid_class_per = 50;
    int low_class_per = 40;
    int lpoptotal = (faction_pop/100) * low_class_per;
    int lpop_count = 0;
    int mpoptotal = (faction_pop/100) * mid_class_per;
    int hpoptotal = (faction_pop/100) * high_class_per;
    //calucates certain percentage of low class
    int mid_class_pop = (faction_pop/100) * mid_class_per;
    int high_class_pop = (faction_pop/100) * high_class_per;
    System.Random random_now = new System.Random();
    for(int i = 0; i < replimit_check && pop_counter < faction_pop;i++)
    {
        //keeps total of low class rep population by 1,000s
        if(lpop_count > lpoptotal)
        {
            Debug.Log("Low class generation complete");
            pop_class[i] = 0;
            display_high_class();
            i--;//brings incrementer back once
            break;
        }
        pop_class[i] = random_now.Next(20);
        pop_counter = pop_increase + pop_counter;
        lpop_count = pop_increase + lpop_count;
        if(debug_on)
            Debug.Log(string.Format("Pop_class index value {0} value = {0} ",i,pop_class[i])); //debug.log is bugged
    }
    return 0;
}

Debug.Log(string.Format("Pop_class index value {0} value = {0} ",i,pop_class[i])); //debug.log is bugged

Debug.Log(string.Format("Pop_class index value {0} value = {1} ",i,pop_class[i])); //debug.log is bugged
