Question

我正在开发C＃应用程序，但在输入xml文件时遇到了问题。让我先说一下代码：

Company comp = new Company();
comp.CompanyID = comboBox1.SelectedValue.ToString();
comp.CompanyName = comboBox1.Text;
comp.Serial = strEncryptedData;
comp.ListProduct = ll;

XmlDocument xDoc = new XmlDocument();
using (StringWriter stringWriter = new StringWriter())
{
    XmlSerializer serializer = new XmlSerializer(typeof(Company));
    serializer.Serialize(stringWriter, comp);
    xDoc.LoadXml(stringWriter.ToString());
}
string temp = xDoc.OuterXml;
MessageBox.Show(temp);
System.IO.StreamWriter sw = new System.IO.StreamWriter(@"c:\test.xml");
sw.WriteLine(temp);
sw.Flush();
sw.Close();

程序写入文件但是当我尝试以xml格式打开它时，我收到空白文档，里面没有任何内容。当我在文本编辑器中打开它时，我收到了这个：

<?xml version="1.0" encoding="utf-16"?><CompanyXml xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><CompanyName /><CompanyID>100</CompanyID><Serial>00000G2SB4BER9PSFJİ2GTVM2UC1VYEİ</Serial></CompanyXml>

这是我收到的正确数据，但无法以xml格式打开。

我该如何格式化？或者我在写作时做错了什么？

Answer 1

只需从第一行xml中删除此文本 encoding =＆＃34; utf-16＆＃34; ，然后您将打开xml。

Answer 2

问题似乎与编码有关，删除utf-16或更改为utf-8会对其进行更正。

您可以尝试使用编码的StreamWriter constructor来查看是否使用正确的编码保存.xml。

例如：

StreamWriter sw = new StreamWriter(@"c:\test.xml", Encoding.UTF8);

Answer 3

然而，在你们指出utf格式问题之后，我找到了一些解决这个问题的方法。

首先，我们创建一个扩展为StringWriter

的类

public class Utf8StringWriter : StringWriter
{
    public override Encoding Encoding
    {
        get { return Encoding.UTF8; }
    }
}

然后我们通过修改 StringWriter ：

来编写代码

Company comp = new Company();
comp.CompanyID = comboBox1.SelectedValue.ToString();
comp.CompanyName = comboBox1.Text;
comp.Serial = strEncryptedData;
comp.ListProduct = ll;

XmlDocument xDoc = new XmlDocument();
using (StringWriter stringWriter = new Utf8StringWriter())
{
    XmlSerializer serializer = new XmlSerializer(typeof(Company));
    serializer.Serialize(stringWriter, comp);
    StreamWriter sw = new StreamWriter(@"c:\text.xml");
    sw.WriteLine(stringWriter);
    sw.Flush();
    sw.Close();
}

...问候
