[英]calculate and display file MD5 Hash in a label
如何计算文件的MD5哈希并在标签中显示?
Yes it is possible: 对的,这是可能的:
label1.Text = GetMD5HashFromFile("somefile.txt");
where the GetMD5HashFromFile
function could look like this: 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();
}
}
Yes, it's possible. 是的,这是可能的。 When you calculate the MD5 Hash of a file you just need to take the result and place it in as the text of Label control. 计算文件的MD5哈希时,只需要获取结果并将其作为Label控件的文本放入。 No problem there. 没问题。
