convert string to byte[]

Question

如何在C＃中将字符串转换为byte []？

Answer 1

请注意，.NET字符串编码为Unicode （UTF-16）：

byte[] bytes = Encoding.Unicode.GetBytes("a string");

Answer 2

使用byte[] data = Encoding.UTF8.GetBytes(myString);

Answer 3

You can use LINQ:

var input     = "myValue";
var byteInput = input.ToCharArray ().Select ( character => ( byte ) character ).ToArray ();

Assert.AreEqual ( input, new string ( byteInput.Select ( character => ( char ) character ).ToArray () ) );

And add the encoding before or after if encoding is something you want to do.
