如何将数据从Windows窗体保存到XML文件？

I pretty sure I have to create some sort of mold of what the XML file has to look like first, right?

我非常肯定我必须首先创建一些XML文件的模型,对吧?

Any help will be appreciated.

任何帮助将不胜感激。

One simple way to do this would be to create .NET classes that you put the data in and then use XmlSerializer to serialize the data to a file and then later deserialize back into an instance of the class and re-populate the form.

一种简单的方法是创建将数据放入的.NET类,然后使用XmlSerializer将数据序列化为文件,然后反序列化为类的实例并重新填充表单。

AS an example, if you have a form with customer data. To keep it short we will just have first name and last name. You can create a class to hold the data. Keep in mind this is just a simple example, you can store arrays and all kinds of complex/nested data like this.

例如,如果您有一个包含客户数据的表单。为了简短起见,我们将只有名字和姓氏。您可以创建一个类来保存数据。请记住,这只是一个简单的示例,您可以像这样存储数组和各种复杂/嵌套数据。

public class CustomerData
{
  public string FirstName;
  public string LastName;
}

So save the data as XML your code will look something like this.

因此,将数据保存为XML,您的代码将如下所示。

// Create an instance of the CustomerData class and populate
// it with the data from the form.
CustomerData customer = new CustomerData();
customer.FirstName = txtFirstName.Text;
customer.LastName = txtLastName.Text;

// Create and XmlSerializer to serialize the data to a file
XmlSerializer xs = new XmlSerializer(typeof(CustomerData));
using (FileStream fs = new FileStream("Data.xml", FileMode.Create))
{
  xs.Serialize(fs, customer);
}

And loading the data back would be something like the following

然后加载数据将类似于以下内容

CustomerData customer;
XmlSerializer xs = new XmlSerializer(typeof(CustomerData));
using (FileStream fs = new FileStream("Data.xml", FileMode.Open))
{
  // This will read the XML from the file and create the new instance
  // of CustomerData
  customer = xs.Deserialize(fs) as CustomerData;
}

// If the customer data was successfully deserialized we can transfer
// the data from the instance to the form.
if (customer != null)
{
  txtFirstName.Text = customer.FirstName;
  txtLastName.Text = customer.LastName;
}

look at using Linq to xml - http://msdn.microsoft.com/en-us/library/bb387098.aspx there are tutorials here that will guide you through creating and querying an xml document.

So, are you wanting to collect data from a user in a Windows form application and then write it out to an XML file (when they click OK)? If so, I'd check out the XmlTextWriter class ( http://msdn.microsoft.com/en-us/library/system.xml.xmltextwriter.aspx ).

那么,您是否希望从Windows表单应用程序中的用户收集数据,然后将其写入XML文件(当他们单击确定时)?如果是这样,我将查看XmlTextWriter类(http://msdn.microsoft.com/en-us/library/system.xml.xmltextwriter.aspx)。
