我发现这更有帮助，因为它是一个扩展，它允许您选择代码的源代码。

static string
    numbers = "0123456789",
    letters = "abcdefghijklmnopqrstvwxyz",
    lettersUp = letters.ToUpper(),
    codeAll = numbers + letters + lettersUp;

static Random m_rand = new Random();

public static string GenerateCode(this int size)
{
    return size.GenerateCode(CodeGeneratorType.All);
}

public static string GenerateCode(this int size, CodeGeneratorType type)
{
    string source;

    if (type == CodeGeneratorType.All)
    {
        source = codeAll;
    }
    else
    {
        StringBuilder sourceBuilder = new StringBuilder();
        if ((type & CodeGeneratorType.Letters) == CodeGeneratorType.Numbers)
            sourceBuilder.Append(numbers);
        if ((type & CodeGeneratorType.Letters) == CodeGeneratorType.Letters)
            sourceBuilder.Append(letters);
        if ((type & CodeGeneratorType.Letters) == CodeGeneratorType.LettersUpperCase)
            sourceBuilder.Append(lettersUp);

        source = sourceBuilder.ToString();
    }

    return size.GenerateCode(source);
}

public static string GenerateCode(this int size, string source)
{
    StringBuilder code = new StringBuilder();
    int maxIndex = source.Length-1;
    for (int i = 0; i < size; i++)
    {

        code.Append(source[Convert.ToInt32(Math.Round(m_rand.NextDouble() * maxIndex))]);
    }

    return code.ToString();
}

public enum CodeGeneratorType { Numbers = 1, Letters = 2, LettersUpperCase = 4, All = 16 };

希望这能有所帮助。

你好，你可以使用WordGenerator或LoremIpsumGenerator从MMLib。RapidPrototyping nuget package。

using MMLib.RapidPrototyping.Generators;
public void WordGeneratorExample()
{
   WordGenerator generator = new WordGenerator();
   var randomWord = generator.Next();

   Console.WriteLine(randomWord);
}

如果您想为强密码生成一串数字和字符。

private static Random random = new Random();

private static string CreateTempPass(int size)
        {
            var pass = new StringBuilder();
            for (var i=0; i < size; i++)
            {
                var binary = random.Next(0,2);
                switch (binary)
                {
                    case 0:
                    var ch = (Convert.ToChar(Convert.ToInt32(Math.Floor(26*random.NextDouble() + 65))));
                        pass.Append(ch);
                        break;
                    case 1:
                        var num = random.Next(1, 10);
                        pass.Append(num);
                        break;
                }
            }
            return pass.ToString();
        }

我添加了使用Ranvir溶液选择长度的选项

public static string GenerateRandomString(int length)
    {
        {
            string randomString= string.Empty;

            while (randomString.Length <= length)
            {
                randomString+= Path.GetRandomFileName();
                randomString= randomString.Replace(".", string.Empty);
            }

            return randomString.Substring(0, length);
        }
    }

我创建了这个方法。

效果很好。

public static string GeneratePassword(int Lenght, int NonAlphaNumericChars)
    {
        string allowedChars = "abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNOPQRSTUVWXYZ0123456789";
        string allowedNonAlphaNum = "!@#$%^&*()_-+=[{]};:<>|./?";
        Random rd = new Random();

        if (NonAlphaNumericChars > Lenght || Lenght <= 0 || NonAlphaNumericChars < 0)
            throw new ArgumentOutOfRangeException();

            char[] pass = new char[Lenght];
            int[] pos = new int[Lenght];
            int i = 0, j = 0, temp = 0;
            bool flag = false;

            //Random the position values of the pos array for the string Pass
            while (i < Lenght - 1)
            {
                j = 0;
                flag = false;
                temp = rd.Next(0, Lenght);
                for (j = 0; j < Lenght; j++)
                    if (temp == pos[j])
                    {
                        flag = true;
                        j = Lenght;
                    }

                if (!flag)
                {
                    pos[i] = temp;
                    i++;
                }
            }

            //Random the AlphaNumericChars
            for (i = 0; i < Lenght - NonAlphaNumericChars; i++)
                pass[i] = allowedChars[rd.Next(0, allowedChars.Length)];

            //Random the NonAlphaNumericChars
            for (i = Lenght - NonAlphaNumericChars; i < Lenght; i++)
                pass[i] = allowedNonAlphaNum[rd.Next(0, allowedNonAlphaNum.Length)];

            //Set the sorted array values by the pos array for the rigth posistion
            char[] sorted = new char[Lenght];
            for (i = 0; i < Lenght; i++)
                sorted[i] = pass[pos[i]];

            string Pass = new String(sorted);

            return Pass;
    }

一个LINQ单行程序(假设私有静态随机随机)…

public static string RandomString(int length)
{
    return new string(Enumerable.Range(0, length).Select(_ => (char)Random.Next('a', 'z')).ToArray());
}
