c# - 计算并在标签中显示文件 MD5 Hash

Question

如何计算文件的 MD5 Hash 并显示在标签中？

Answer 1

是的，这是可能的:

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

GetMD5HashFromFile 函数可能如下所示:

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();
    }
}
