将字符串转换为byte[]

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

注意。net字符串被编码为Unicode (UTF-16):

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

您可以使用LINQ:

var input     = "myValue";
var byteInput = input.ToCharArray ().Select ( character => ( byte ) character ).ToArray ();
Assert.AreEqual ( input, new string ( byteInput.Select ( character => ( char ) character ).ToArray () ) );

如果您想要编码，则在编码之前或之后添加编码
