在 vb.net 中生成随机字符串

我需要在 vb.net 中生成随机字符串，该字符串必须由（随机选择的）字母 A-Z （必须大写）和散布的随机数字组成。它还需要能够生成具有设定长度的它们。

感谢您的帮助，这让我发疯！

如果你可以将其转换为 VB.NET（这很简单），我想说你就可以了（如果你不能，请使用this http://www.developerfusion.com/tools/convert/csharp-to-vb/或任何其他有价值的工具）：

/// <summary>
/// The Typing monkey generates random strings - can't be static 'cause it's a monkey.
/// </summary>
/// <remarks>
/// If you try hard enough it will eventually type some Shakespeare.
/// </remarks>
class TypingMonkey
{
   private const string legalCharacters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890";

   static Random random = new Random();

   /// <summary>
   /// The Typing Monkey Generates a random string with the given length.
   /// </summary>
   /// <param name="size">Size of the string</param>
   /// <returns>Random string</returns>
   public string TypeAway(int size)
   {
       StringBuilder builder = new StringBuilder();
       char ch;

       for (int i = 0; i < size; i++)
       {
           ch = legalCharacters[random.Next(0, legalCharacters.Length)];
           builder.Append(ch);
       }

       return builder.ToString();
    }
}

那么你所要做的就是：

TypingMonkey myMonkey = new TypingMonkey();
string randomStr = myMonkey.TypeAway(size);
