ICSFile：重新封装C# File类

编辑:dnawo 日期:2015-01-29

当路径D:\web\不存在时，下边两个语句都会抛错：

复制内容到剪贴板程序代码 程序代码
File.WriteAllText(@"D:\web\index.htm", "mzwu.com");
File.ReadAllText(@"D:\web\index.htm");



平时调用WriteAllText前都得先调用Directory.Exists和Directory.CreateDirectory，换句话说，创建文件和创建所属文件夹应为一个整体，而读取文件时，创建所属文件夹显然不合适，基于这一原则，重新封装了C# File类：

复制内容到剪贴板程序代码 程序代码
public static class ICSFile
{
    private static readonly Encoding DEFAULTENCODE = Encoding.UTF8;

    /// <summary>
    /// 创建父文件夹
    /// </summary>
    /// <param name="path"></param>
    /// <returns></returns>
    private static void CreateDirectory(string path)
    {
        string dir = Path.GetDirectoryName(path);
        if (!Directory.Exists(dir))
        {
            Directory.CreateDirectory(dir);
        }
    }

    /// <summary>
    /// 追加文本
    /// </summary>
    /// <param name="path"></param>
    /// <param name="contents"></param>
    public static void AppendAllText(string path, string contents)
    {
        AppendAllText(path, contents, DEFAULTENCODE);
    }

    /// <summary>
    /// 追加文本
    /// </summary>
    /// <param name="path"></param>
    /// <param name="contents"></param>
    /// <param name="encoding"></param>
    public static void AppendAllText(string path, string contents, Encoding encoding)
    {
        CreateDirectory(path);
        File.AppendAllText(path, contents, encoding);
    }

    /// <summary>
    /// 复制文件
    /// </summary>
    /// <param name="sourceFileName"></param>
    /// <param name="destFileName"></param>
    public static void Copy(string sourceFileName, string destFileName)
    {
        Copy(sourceFileName, destFileName, false);
    }

    /// <summary>
    /// 复制文件
    /// </summary>
    /// <param name="sourceFileName"></param>
    /// <param name="destFileName"></param>
    /// <param name="overwrite"></param>
    public static void Copy(string sourceFileName, string destFileName, bool overwrite)
    {
        CreateDirectory(destFileName);
        File.Copy(sourceFileName, destFileName, overwrite);
    }

    /// <summary>
    /// 删除文件
    /// </summary>
    /// <param name="path"></param>
    public static void Delete(string path)
    {
        File.Delete(path);
    }

    /// <summary>
    /// 判断文件是否存在
    /// </summary>
    /// <param name="path"></param>
    /// <returns></returns>
    public static bool Exists(string path)
    {
        return File.Exists(path);
    }

    /// <summary>
    /// 移动文件
    /// </summary>
    /// <param name="sourceFileName"></param>
    /// <param name="destFileName"></param>
    public static void Move(string sourceFileName, string destFileName)
    {
        Move(sourceFileName, destFileName, false);
    }

    /// <summary>
    /// 移动文件
    /// </summary>
    /// <param name="sourceFileName"></param>
    /// <param name="destFileName"></param>
    /// <param name="overwrite"></param>
    public static void Move(string sourceFileName, string destFileName, bool overwrite)
    {
        if (overwrite && File.Exists(destFileName))
        {
            File.Delete(destFileName);
        }
        CreateDirectory(destFileName);
        File.Move(sourceFileName, destFileName);
    }

    /// <summary>
    /// 读取文件
    /// </summary>
    /// <param name="path"></param>
    /// <returns></returns>
    public static string ReadAllText(string path)
    {
        return ReadAllText(path, DEFAULTENCODE);
    }

    /// <summary>
    /// 读取文件
    /// </summary>
    /// <param name="path"></param>
    /// <param name="encoding"></param>
    /// <returns></returns>
    public static string ReadAllText(string path, Encoding encoding)
    {
        return File.ReadAllText(path, encoding);
    }

    /// <summary>
    /// 创建一个新文件写入文本
    /// </summary>
    /// <param name="path"></param>
    /// <param name="contents"></param>
    public static void WriteAllText(string path, string contents)
    {
        WriteAllText(path, contents, DEFAULTENCODE);
    }

    /// <summary>
    /// 创建一个新文件写入文本
    /// </summary>
    /// <param name="path"></param>
    /// <param name="contents"></param>
    /// <param name="encoding"></param>
    public static void WriteAllText(string path, string contents, Encoding encoding)
    {
        CreateDirectory(path);
        File.WriteAllText(path, contents, encoding);
    }
}
