问题描述
我需要生成一个带有空格和MixedCase的随机字符串.
I am in need of generating a random string with spaces and mixedCase.
这是我到目前为止所获得的:>
This is all I got so far:
/// <summary>
/// The Typing monkey generates random strings - can't be static 'cause it's a monkey.
/// </summary>
/// <remarks>
/// If you wait long enough it will eventually produce Shakespeare.
/// </remarks>
class TypingMonkey
{
/// <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();
Random random = new Random();
char ch;
for (int i = 0; i < size; i++)
{
ch = Convert.ToChar(Convert.ToInt32(Math.Floor(26 * random.NextDouble() + 65)));
builder.Append(ch);
}
return builder.ToString();
}
}
我只得到没有空格的大写字符串-我相信该调整应该很明确,以便在汤中混合大小写和空格.
I am getting only uppercase strings with no spaces - I believe the tweak should be pretty striaghtforward to get mixed case and spaces in the soup.
任何帮助,我们将不胜感激!
Any help greatly appreciated!
推荐答案
最简单的方法是简单地创建一个具有以下值的字符串:
The easiest way to do this is to simply create a string with the following values:
private readonly string legalCharacters = " abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
然后使用RNG访问此字符串中的随机元素:
Then use the RNG to access a random element in this string:
public string TypeAway(int size)
{
StringBuilder builder = new StringBuilder();
Random random = new Random();
char ch;
for (int i = 0; i < size; i++)
{
ch = legalCharacters[random.Next(0, legalCharacters.Length)];
builder.Append(ch);
}
return builder.ToString();
}
