複製代碼

MD5 md5Hasher = MD5.Create();
byte[] data = md5Hasher.ComputeHash(Encoding.Default.GetBytes(textBox1.Text));
StringBuilder sBuilder = new StringBuilder();
for (int i = 0; i < data.Length; i++)
{
sBuilder.Append(data[i].ToString("x"));
}
textBox2.Text = sBuilder.ToString();

string[] temp = txt_Source.Lines;
double[] randomIndex = new double[temp.Length];
Random r = new Random(Guid.NewGuid().GetHashCode());
for (int i = 0; i < temp.Length; i++)
{
randomIndex[i] = r.NextDouble();
}
Array.Sort(randomIndex, temp);
txt_Result.Lines = temp;
