如何修复错误CS0136

Question

我有一个给我错误的脚本

  

Assets / Scripts / CraftItem.cs（11,6）：错误CS0136：局部变量   名为requiredcount' cannot be declared in this scope because it would give a different meaning to requiredcount＆＃39;已经是   用于“父母或现在的”＃39;范围来表示别的东西

我无法在网上找到任何好的答案，也不知道如何解决这个问题，以下是剧本：

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;



    public class CraftItem : MonoBehaviour {

         public GameObject countholder;

         public void Craftitem(int crafttype, int requiredtype, int requiredcount, int requiredamount){
             requiredcount = countholder.GetComponent<Counts> ().Counters [requiredtype];
                 if(requiredcount => requiredamount){

             }

         }
     }

Answer 1

您在if条件中使用>=，在C＃中表示箭头函数/ lambda表达式。您正在寻找的运营商是if (age1>age2 && age1>age3) { oldest=age1; if (age2>age3) middle = age2; youngest=age3; } else { middle = age3; youngest=age2; } } else if (age2>age3) { oldest=age2; if (age1>age3) middle = age1; youngest=age3; } else { middle = age3; youngest=age1; } } else { oldest=age3; if (age2>age1) middle = age2; youngest=age1; } else { middle = age1; youngest=age2; } }
