在用c#做项目时，尤其是配置文件时，会遇到各种文件的操作处理。所以，我将几种常见的文件操作处理方法整理了一下，如有问题，欢迎指正。
txt：
#region txt
/// <summary>
/// 创建一个空的txt
/// </summary>
/// <param name="FileName">路径文件名带后缀</param>
public void Create_txt(string FileName)
{
StreamWriter sw = new StreamWriter(FileName);
sw.Close();
}
/// <summary>
/// 写入txt
/// </summary>
/// <param name="FileName">路径文件名带后缀</param>
/// <param name="condition">true为追加写入，false为覆盖写入</param>
/// <param name="s">写入数据</param>
public void WriteData_txt(string FileName, bool condition, string s)
{
StreamWriter sw = new StreamWriter(FileName, condition);
sw.WriteLine(s);
sw.Close();
}
/// <summary>
/// 读取txt '_' ',' 为截取符
/// </summary>
/// <param name="FileName">路径文件名带后缀</param>
/// <param name="listbox">读取内容显示</param>
public void ReadData_txt(string FileName, ListBox listbox)
{
listbox.Items.Clear();
string ORead;
string[] splitstrings;
using (StreamReader sr = new StreamReader(FileName))
{
while (sr.Peek() >= 0)
{
ORead = sr.ReadLine();
//截取
char[] separator = {
'_', ',' };
splitstrings = ORead.Split(separator);
for (int i = 0; i < splitstrings.Length; i++)
{
listbox.Items.Add(splitstrings[i] + '\n');
}
}
sr.Close();
}
}
#endregion
csv：
#region csv
/// <summary>
/// 创建一个空的csv文件
/// </summary>
/// <param name="path">路径</param>
/// <param name="filename">文件名带后缀</param>
public static void CreateCsv(string path, string filename)
{
if (File.Exists(Path.Combine(path, filename)))
{
MessageBox.Show("该文件已存在", "错误");
}
else
{
string s = path + filename;
StreamWriter sw = new StreamWriter(s);
//sw.WriteLine("");
sw.Close();
sw.Dispose();
MessageBox.Show("创建成功");
}
}
/// <summary>
/// 向csv文件中写入数据
/// </summary>
/// <param name="path">路径</param>
/// <param name="filename">文件名带后缀</param>

//自动以','分隔开
sw.WriteLine(s);
sw.Close();
sw.Dispose();
}
#endregion
ini：
#region 写入ini
[DllImport("kernel32")]
private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);
/// <summary>

/// </summary>

#endregion
xml：
在处理xml文件时，应当注意xml文件的各级节点的名字的要求，xml文件的二级节点名不能以数字和特殊字符开头(’_'除外)，文件名不能以特殊字符开头。
/// <summary>
/// 判断字符串是否以数字或者特殊字符开头 ,"_"除外
/// </summary>

XmlDeclaration declaration = XDoc.CreateXmlDeclaration("1.0", "UTF-8", "yes");
XDoc.AppendChild(declaration);
XmlElement elem = XDoc.CreateElement(root);
XDoc.AppendChild(elem);
XDoc.Save(FileName);
}
/// <summary>
/// 读取显示整个xml文档
/// </summary>
/// <param name="FileName">路径文件名带后缀</param>
/// <param name="listBox">读取内容显示</param>
public static void ReadXml_All(string FileName, ListBox listBox)
{
listBox.Items.Clear();
listBox.Items.Add("文件名：");
listBox.Items.Add(FileName);
listBox.Items.Add(" ");
listBox.Items.Add("<?xml version=\"1.0\" encoding=\"UTF-8\"?> ");
XDocument doc = XDocument.Load(FileName);
XElement root = doc.Root;
listBox.Items.Add("<" + root.Name + ">");
IEnumerable<XElement> listnode = root.Elements();
foreach (XElement item in listnode)
{
listBox.Items.Add(" <" + item.Name + ">");
var nodes = item.Elements();
foreach (var noddd in nodes)
{
listBox.Items.Add(" " + noddd);
}
listBox.Items.Add(" </" + item.Name + ">");

以上为这些文件的常用基本操作的部分方法，如有问题或补充欢迎各位指正。
