How to convert utf8 string to utf8 byte array?
提问by valch
How can I convert string to utf8 byte array, I have this sample code:
如何将字符串转换为 utf8 字节数组，我有这个示例代码：
This works ok:
这工作正常：
StreamWriter file = new StreamWriter(file1, false, Encoding.UTF8);
file.WriteLine(utf8string);
file.Close();
This works wrong, file is in ASCII:
这是错误的，文件是 ASCII：
byte[] bytes = System.Text.UTF8Encoding.UTF8.GetBytes(utf8string);
FileStream fs = new FileStream(file2, FileMode.CreateNew);
fs.Write(bytes, 0, bytes.Length);
fs.Close();
I would like to get byte array what returned by this function:
我想得到这个函数返回的字节数组：
System.IO.File.ReadAllBytes(path_to_file)
because this works ok:
因为这可以正常工作：
byte[] datab = File.ReadAllBytes(file1);
FileStream fs2 = new FileStream(file3, FileMode.CreateNew);
fs2.Write(datab, 0, datab.Length);
fs2.Close();

Can use other option again:
可以再次使用其他选项：
string value = "\u00C4 \uD802\u0033 \u00AE";
byte[] bytes= System.Text.Encoding.UTF8.GetBytes(value);
For more information can look on Encoding.UTF8 Property
更多信息可以查看Encoding.UTF8 属性

You just wanted to convert utf8string to bytes, what are these filestreams for?
您只是想将 utf8string 转换为字节，这些文件流是做什么用的？
String ValueToConvert = "Stack overflow";
byte[] ConvertedBytes = ValueToConvert.getBytes("UTF-8");
