Question

我已经实例化了XmlDocument，而不是尝试在文件pat中加载带有非拉丁符号的XML文件。在加载我面对的文件

期间

 ArgumentNullException

带有消息：

"Value cannot be null. Parameter name: str"

Stack Trace是 -

我的代码中有一部分：

var xmlData = new XmlDocument();
if (File.Exists(xmlPath))
{        
    xmlData.Load(xmlPath);
    ...
}

xmlPath包含法语字母。

有什么问题？如何用非拉丁字符打开xml文件？

Answer 1

我找到了使用其他类进行数据加载的问题的解决方案，如下所示：

var d = File.ReadAllText(xmlPath);
xmlData.LoadXml(d);

但问题 - “出了什么问题？”仍然开放。

Answer 2

首先将文件路径加载到uri：

Uri xmlUri = new Uri(xmlPath);
xmlData.Load(xmlUri.AbsolutePath);

从具有非拉丁文件路径的文件加载XmlDocument
