打开xml：
string xmlstring = """";
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog dialog = new OpenFileDialog();
dialog.InitialDirectory = Application.StartupPath;
dialog.Filter = ""All Files|.|xml file(.xml)|.xml"";
dialog.RestoreDirectory = true;
if (dialog.ShowDialog() == DialogResult.OK)
{
string filepath = dialog.FileName.ToString();
string filename = filepath.Substring(filepath.LastIndexOf(""\"") + 1);
textBox1.Text = filepath;
using (StreamReader sr = new StreamReader(filepath, Encoding.Default))//如果乱码，可改为System.Text.Encoding.UTF-8;或者System.Text.Encoding.GBK
{
string //代码效果参考：https://v.youku.com/v_show/id_XNjM5OTIwOTcxNg==.html
str;string line = """";
while ((str = sr.ReadLine()) != null)
{
line += str;
}
xmlstring = line;
}
}
richTextBox1.Text = xmlstring;
}
格式化xml：
private string FormatXml(string sUnformattedXml)
{
StringReader Reader = new StringReader(sUnformattedXml);
XmlDocument xd = new XmlDocument();
xd.Load(Reader);
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
XmlTextWriter xtw = null;
try
{
xtw = new XmlTextWriter(sw);
xtw.Formatting = Formatting.Indented;
//代码效果参考：https://v.youku.com/v_show/id_XNjM5OTI3MjQ2OA==.html
xtw.Indentation = 1;xtw.IndentChar = '\t';
xd.WriteTo(xtw);
}
finally
{
if (xtw != null)
xtw.Close();
}
return sb.ToString();
}
3.获取xml内容：
public string AllChildNode(string xml)
{
StringReader Reader = new StringReader(xml);
XmlDocument doc = new XmlDocument();
doc.Load(Reader);
string str = """";
XmlNode root = doc.FirstChild;
if (root.HasChildNodes)
{
for (int i = 0; i < root.ChildNodes.Count; i++)
{
str += root.ChildNodes【i】.InnerText;
}
}
return str;
}
