the byte string is same in python and c#,but md5 hashcode is different

[sidooh]

hi,everyone.

I want to generate the hash code from a string,e.g."咖啡" ,but the hashcode I get from python and c# is different,the one from python is what I want

c#

String str = "咖啡";
MD5 m = MD5.Create();
byte[] data = m.ComputeHash(Encoding.Default.GetBytes(str));
StringBuilder sbuilder = new StringBuilder();
for(int i=0;i<data.Length;i++){
* sbuilder.Append(data[i].ToString("x2"));
}
byte[] hex = Encoding.Default.GetBytes(str);
StringBuilder hex_builder = new StringBuilder();
foreach(byte a in hex){
* hex_builder.Append("{0:x2}",a);
}
//md5 hash code
Response.Write(sbuilder.ToString());
//binary string
Response.Write(hex_builder.ToString());

python

str = '咖啡'
m = hashlib.md5()
m.update(str)
#md5 hashcode
print m.hexdigest()
#binary string
print ' '.join(["%02x"%ord(x) for x in str])

binary string is e5 92 96 e5 95 a1 both in c# and python

md5 hash code:
(c#)a761914f976 0af3c112e24f08d ea1b16
(python)3b7daa5 8a1fecdf5ba4d94 d539fbb4d5
