我有一个FileInfo,我知道它是XML,我想转换为XmlDocument。有什么办法可以做到吗? 这是我的代码
string name = "filename";
XmlDocument xml = new XmlDocument();
FileInfo xmlFileInfo = directoryInfo.GetFiles(filename + extension).FirstOrDefault();
//Im trying to do something like: xml = xmlFileInfo as XmlDocument
答案 0 :(得分:5)
您不想将FileInfo
对象转换为XmlDocument
,而是想要将FileInfo
指向的文件的内容加载到此类对象中。
尝试这样做:
var doc = new XmlDocument();
doc.Load(xmlFileInfo.FullName);

这是我一年多以前写的代码。如果您没有读取文件夹的权限,则“获取文件”将失败。因此,解决方案是递归获取每个文件夹。 :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.IO;
namespace WriteFileNamesXml
{
class Program
{
const string FILENAME = @"c:\temp\test.xml";
const string FOLDER = @"c:\temp";
static XmlWriter writer = null;
static void Main(string[] args)
{
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
writer = XmlWriter.Create(FILENAME, settings);
writer.WriteStartDocument(true);
DirectoryInfo info = new DirectoryInfo(FOLDER);
WriteTree(info);
writer.WriteEndDocument();
writer.Flush();
writer.Close();
}
static long WriteTree(DirectoryInfo info)
{
long size = 0;
writer.WriteStartElement("Folder");
try
{
writer.WriteAttributeString("name", info.Name);
writer.WriteAttributeString("numberSubFolders", info.GetDirectories().Count().ToString());
writer.WriteAttributeString("numberFiles", info.GetFiles().Count().ToString());
writer.WriteAttributeString("date", info.LastWriteTime.ToString());
foreach (DirectoryInfo childInfo in info.GetDirectories())
{
size += WriteTree(childInfo);
}
}
catch (Exception ex)
{
string errorMsg = string.Format("Exception Folder : {0}, Error : {1}", info.FullName, ex.Message);
Console.WriteLine(errorMsg);
writer.WriteElementString("Error", errorMsg);
}
FileInfo[] fileInfo = null;
try
{
fileInfo = info.GetFiles();
}
catch (Exception ex)
{
string errorMsg = string.Format("Exception FileInfo : {0}, Error : {1}", info.FullName, ex.Message);
Console.WriteLine(errorMsg);
writer.WriteElementString("Error", errorMsg);
}
if (fileInfo != null)
{
foreach (FileInfo finfo in fileInfo)
{
try
{
writer.WriteStartElement("File");
writer.WriteAttributeString("name", finfo.Name);
writer.WriteAttributeString("size", finfo.Length.ToString());
writer.WriteAttributeString("date", info.LastWriteTime.ToString());
writer.WriteEndElement();
size += finfo.Length;
}
catch (Exception ex)
{
string errorMsg = string.Format("Exception File : {0}, Error : {1}", finfo.FullName, ex.Message);
Console.WriteLine(errorMsg);
writer.WriteElementString("Error", errorMsg);
}
}
}
writer.WriteElementString("size", size.ToString());
writer.WriteEndElement();
return size;
}
}
