You may wonder how the mining works, this is the method telling the basic idea the condtition of mining. In a nutshell, you mined the block successfully if you found a hash with certain number of leading '0's in it.

 public void Mine(int difficulty)
 {
     // You mined successfully if you found a hash with certain number of leading '0's
     // difficulty defines the number of '0's required 
     // e.g. if difficulty is 2, if you found a hash like  00338500000x..., it means you mined it.
     while (this.Hash.Substring(0, difficulty) != new String('0', difficulty))
     {
         this._salt++;
         this.Hash = this.CalculateHash();
         Console.WriteLine("Mining:" + this.Hash);
     }

     Console.WriteLine("Block has been mined: " + this.Hash);
 }
