使用C＃的Xml编辑问题
|
我之前发布了一个有关通过C＃编辑xml文档的问题
C＃写入XML错误
但是我现在又遇到麻烦了。我使用的是当时可以使用的确切代码，但是又遇到了问题！
当我第一次单击该按钮时，它似乎可以工作，但是当我再次单击该按钮时，出现错误
Data at the root level is invalid. Line 83, position 10
\"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\"
path = test.xml
using (FileStream READER = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
System.Xml.XmlDocument Temp = new System.Xml.XmlDocument();
Temp.Load(READER);
using (FileStream WRITER = new FileStream(path, FileMode.Open, FileAccess.Write, FileShare.ReadWrite))
{
Temp.Save(WRITER);
}
}
