计算并在标签中显示MD5 Hash文件

Question

如何计算文件的MD5哈希并在标签中显示？

Answer 1

对的,这是可能的:

label1.Text = GetMD5HashFromFile("somefile.txt");

在GetMD5HashFromFile功能看起来是这样的:

public static string GetMD5HashFromFile(string filename)
{
    using (var md5 = new MD5CryptoServiceProvider())
    {
        var buffer = md5.ComputeHash(File.ReadAllBytes(filename));
        var sb = new StringBuilder();
        for (int i = 0; i < buffer.Length; i++)
        {
            sb.Append(buffer[i].ToString("x2"));
        }
        return sb.ToString();
    }
}
