       StreamWriter file = new StreamWriter(path+"log.txt");

       file.WriteLine(passhash);
       file.Close();

       txt_pass.Text = "";
   }
   public static string MD5Hash(string text)
   {
       MD5 md5 = new MD5CryptoServiceProvider();

       //compute hash from the bytes of text
       md5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(text));

       //get hash result after compute it
       byte[] result = md5.Hash;

       StringBuilder strBuilder = new StringBuilder();
       for (int i = 0; i < result.Length; i++)
       {
           //change it into 2 hexadecimal digits
           //for each byte
           strBuilder.Append(result[i].ToString("x2"));
       }

       return strBuilder.ToString();
   }

推荐答案

一对建议..



1.创建新的streamwriter实例时，可以指定文件访问模式。例如，打开或创建，追加。



2.在file.close（）方法之前，刷新缓冲区即file.flush（）。 Flush将清除缓冲区并将流写入文件。

Couple of suggestions..

1. When you create new instance of streamwriter, you can specify the file access mode. For example, open or create, append.

2. Before the file.close() method, flush the buffer i.e file.flush(). Flush will clear the buffer and write the stream to file.
