I am trying to batch convert quite a number of CSV files present encoding to UTF-8 through .NET

What I have been doing till now is opening the csv file one by one and selecting "all files" from the "save as/format type" dropdown box and selecting the encoding as "UTF-8" again from the dropdown box below it and then I save it (It doesn't asks to replace the original file though).

As this procedure is quite tedious, I would like to write a tiny app for it in vb.NET

All I came up with is this: System.Text.Encoding.Convert(System.Text.Encoding.ASCII,System.Text.Encoding.UTF-8)

But thats creating an error :(

Any suggestions? Thx

UPDATE: Just updated my question to use .NET's internal lib/funcs instead of using Notepad :D

看看DirectoryInfo枚举目录中的文件。

File.ReadAllText()然后看看File.WriteAllText()哪些是您可以轻松用于转换编码的便捷方法。

请注意，如果您希望在文件开头没有签名的 UTF-8 (U+FEFF)，则需要使用

var encoding = new UTF8Encoding(false);

如果这是一次性的，请启动 PowerShell：

gci *.csv | %{ Get-Content $_ | Set-Content -Encoding UTF8 "$($_.BaseName)_Encoded.csv" }

gci *.csv ：获取当前目录中的所有 csv 文件并将结果通过管道传输到“foreach”循环 (%) 每个文件的 Get-Content 然后将结果通过管道传输到执行 UTF8 转换的 Set-Content 并将结果存储在具有相同基本名称的文件，后缀为“_Encoded”。

试试这个： Mozilla 的字符集检测器或它的 .NET 端口。
