在我使用按钮创建的一个类中单击XML文档:
private void buttonCreate_Click(object sender, RoutedEventArgs e)
{
DialogResult result = folderElg.ShowDialog();
if (result == System.Windows.Forms.DialogResult.OK)
{
textBoxPath.Text = folderElg.SelectedPath;
userConfigurePath = folderElg.SelectedPath;
}
XmlDocument toolConfig = new XmlDocument();
XmlNode myRoot;
myRoot = toolConfig.CreateElement("Tool");
toolConfig.AppendChild(myRoot);
toolConfig.Save(@userConfigurePath + "\\config.xml");}
我没有问题。该文件夹已创建,xml文件也已创建。
所以在另一个类中我想将对象序列化为xml文件'config.xml'(变量userConfigurePath在上面提到的classe中是静态的):
public partial class MainWindow : Window
{
private string inputNewTool = "";
private OpenFileDialog dlg = new OpenFileDialog();
public MainWindow()
{
InitializeComponent();
}
private void buttonAdd_Click(object sender, RoutedEventArgs e)
{
InputDialog input = new InputDialog();
input.ShowDialog();
inputNewTool = input.enteredTxt;
if (inputNewTool != null)
{
System.Windows.Forms.MessageBox.Show("Chose the Tool's directory");
dlg.DefaultExt = ".txt";
dlg.Filter = "Text documents (.txt)|*.txt";
if (dlg.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
Tool tool = new Tool();
tool.Name = inputNewTool;
tool.Path = dlg.FileName;
XmlSerializer serializer = new XmlSerializer(tool.GetType());
StreamWriter writer = new StreamWriter(@Start.userConfigurePath +
"\\config.xml");
serializer.Serialize(writer.BaseStream, tool);
}
}
结果是该对象未保存在config.xml文件中。为什么呢?
编辑工具类:
public class Tool
{
public string Name { get; set; }
public string Path { get; set; }
public Tool() { }
}
第二次编辑:
我看到我无法在创建xml文件时删除manuel这些文件夹(在应用程序关闭后)。为什么呢?
第三次编辑:
我改变了我的代码:
if (dlg.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
Tool tool = new Tool();
tool.Name = inputNewTool;
tool.Path = dlg.FileName;
XmlSerializer serializer = new XmlSerializer(tool.GetType());
using (var writer = new StreamWriter(@Start.userConfigurePath +
"\\config.xml"))
{
serializer.Serialize(writer.BaseStream, tool);
writer.Close();
}
现在第一个对象被序列化了。但是如果我以相同的方式创建另一个工具,则config.xml不会接受它。只有第一个工具被序列化:
<?xml version="1.0"?>
<Tool xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Name>dffss</Name>
<Path>D:\Users\xxxx\Documents\schulewochenbericht.txt</Path>
</Tool>

您需要关闭StreamWriter对象以将数据刷新到文件中。请尝试以下方法:
XmlSerializer serializer = new XmlSerializer(tool.GetType());
using (var writer = new StreamWriter(@Start.userConfigurePath + "\\config.xml"))
{
serializer.Serialize(writer.BaseStream, tool);
}

除了wdosanjos的答案之外,你还应该意识到你不能只编写Tool
个对象的序列。如果要编写多个Tool
,则需要编写Tool
的数组或列表。
