Question

当我尝试告诉IF命令检查是否等同于XML文件中的值时，IF命令不允许您这样做。

此代码是读取XML文件的代码：

using System.Collections.Generic;
using System.Linq;
using System.Xml.Linq;
using UnityEngine;

public class ReadXML : MonoBehaviour
{

   // Use this for initialization
   void Start()
   {

     List<Dictionary<string, string>> allTextDic = parseFile();
     Dictionary<string, string> dic = allTextDic[0];

   }

   public List<Dictionary<string, string>> parseFile()
   {
      TextAsset txtXmlAsset = Resources.Load<TextAsset>("riddles");
      var doc = XDocument.Parse(txtXmlAsset.text);

      var allDict = doc.Element("document").Elements("row");
      List<Dictionary<string, string>> allTextDic = new 
      List<Dictionary<string, string>>();
      foreach (var oneDict in allDict)
      {
         var twoStrings = oneDict.Elements("string");
         XElement element1 = twoStrings.ElementAt(0);
         XElement element2 = twoStrings.ElementAt(1);
         string first = element1.ToString().Replace("<string>", 
         "").Replace(" 
         </string>", "");
         string second = element2.ToString().Replace("<string>", 
         "").Replace("</string>", "");

         Dictionary<string, string> dic = new Dictionary<string, string>();
         dic.Add("1", first);
         dic.Add("2", second);

         allTextDic.Add(dic);


     }

     return allTextDic;

  }

}

这是XML文件：

<document>
 <row>
   <string>1</string >
   <string>2</string >
 </row>
 <row>
   <string>3</string >
   <string>4</string >
</row>
<row>
   <string>5</string >
   <string>6</string >
</row>
<row>
   <string>7</string >
   <string>8</string >
</row>

</document>

好的，这是我的问题。当您在Visual Studio上看到此脚本时，下面显示“ dic”的行下有一条红色的弯曲线。为什么呢？ dic [“ 1st”]的值与1相同，但是API不允许这样做，那么我们该如何解决？

public GameObject obj;
private void OnMouseDown()
{
    if (dic["1st"] == 1)
    {
        Instantiate(obj);
    }
}

谢谢！

请小心==运算符；尝试：

public GameObject obj;
private void OnMouseDown()
{
    if (Convert.ToInt32(dic["1st"]) == 1)
    {
        Instantiate(obj);
    }
}

使用IF语句解决与XML相关的问题
