Question

我是Unity和C＃的新手，所以不要和我一起努力;）

我正在尝试读取包含一些配置数据的xml文件（xsd有效，用VS2012生成* .cs），我得到的格式异常显然与xml文件的路径有关。 “test”-field是xml-file-content的主要类。

    xmlLoader = new XMLLoaderSaver ();
    print ("before read");
    test = xmlLoader.readIt ("./Assets/xml/sample.xml");
    print ("after read");
    test.ToString ();

XMLLoaderSaver具有以下代码：

public class XMLLoaderSaver {

public leberDefense readIt(string path){

    var serializer = new XmlSerializer (typeof(leberDefense));
    var stream = new FileStream (path, FileMode.Open, FileAccess.Read);
    var container = serializer.Deserialize (stream) as leberDefense;
    stream.Close();
    return container;
} ...

显然问题是解析路径。经度：

before read
UnityEngine.MonoBehaviour:print(Object)
GameController:Start() (at Assets/scripts/GameController.cs:37)

我真的不明白如何解决这个问题，但也许有人可以帮助我。

谢谢！

编辑：

我的xml文件基本上是这样的：

<root>
    <elem1>
        <s1/>
        <s2/>
        <s3/>
    </elem1>

    <elem2>
      <w>
        <e/>
        <e/>
        <e/>
      </w>

      <w>
        <e/>
        <e/>
        <e/>
      </w>
    </elem2>
</root>

我已经检查了xsd并对其进行了验证，所以这不应该是问题。

将文件路径更改为“。\ Assets \ xml \ sample.xml”不会更改异常。

您的XML不包含任何元素的值，只包含其名称。从您向我们显示的错误中，其中一个字段应该是一个整数，但是不存在数字数据。如果我尝试将空字符串解析为整数，如下所示：

System.Xml.XmlConvert.ToInt32(string.Empty)

或

int.Parse(string.Empty, System.Globalization.NumberStyles.Any, System.Globalization.CultureInfo.InvariantCulture)

我得到了同样的例外：

'System.Xml.XmlConvert.ToInt32(string.Empty)' threw an exception of type 'System.FormatException'
    base {System.SystemException}: {"Input string was not in a correct format."}

您没有向我们展示您的课程，因此我们不知道应该存在哪些值，但是如果字段e应该是数字，则XML应该类似于：

<e>23</e>

您应该确定XML文件不包含实际数据的原因;这可能是你的问题。

如果这不是导致问题的实际XML，您应该向我们展示您尝试阅读它的类的实际XML和骨架。
