C#生成随机序列

1、生成字母和数字结合的随机序列：

Random rn = new Random();

string charsToUse = "AzByCxDwEvFuGtHsIrJqKpLoMnNmOlPkQjRiShTgUfVeWdXcYbZa1234567890";

 

MatchEvaluator RandomChar = delegate (Match m)

{

    return charsToUse[rn.Next( charsToUse.Length )].ToString();

};

 

Console.WriteLine( Regex.Replace( "XXXX-XXXX-XXXX-XXXX-XXXX", "X", RandomChar ) );

// Lv2U-jHsa-TUep-NqKa-jlBx

Console.WriteLine( Regex.Replace( "XXXX", "X", RandomChar ) );

 // 8cPD

2、生成字节随机序列

byte[] randBytes = new byte[108];

Random randNum = new Random();

randNum.NextBytes(randBytes);
