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>

xml:
When processing xml files, you should pay attention to the requirements for the names of nodes at all levels in xml files. The names of secondary nodes in xml files cannot start with numbers and special characters (except '_'), and file names cannot start with special characters.

The above are some of the common basic operations of these files. If you have any questions or supplements, please correct me.
