C# 或 VB.NET：如何以编程方式将给定目录中所有文本文件的编码格式更改为 UTF-8？

Question

我试图循环遍历一个目录，并永远找到我找到的文本文件，将编码转换为 UTF-8 Fromat。

Answer 1

使用 DirectoryInfo 就差不多完成了

DirectoryInfo DI = new DirectoryInfo("TextFiles_Path");
FileInfo[] Files = DI.GetFiles("*.txt");
foreach(FileInfo Fl in Files)
{
    StreamReader SR = Fl.OpenText(); //This opens a stream to the file **in UTF8 encoding**
    StreamWriter SW = new StreamWriter(new FileStream(Fl.FullName + ".UTF8.txt", FileMode.OpenOrCreate), Encoding.UTF8);
    SW.Write(SR.ReadToEnd());
}

Answer 2

快速又简单

For Each oFile In IO.Directory.GetFiles(dir, "*.*", IO.SearchOption.AllDirectories)
    IO.File.WriteAllText(oFile, IO.File.ReadAllText(oFile), Encoding.UTF8)
