推荐答案

随机类在c＃

随机rd = new Random（）;

int no = rd.next（）//得到随机非重复的没有



...你的问题不明确，我想这会有所帮助你要解决你的问题

Random class is there in c#
Random rd=new Random();
int no=rd.next() //get random non repetitive no's

...your question is not clear,I think this will help you to solve your problem

private readonly Random _rng = new Random（）;

private const string _chars = ABCDEFGHIJKLMNOPQRSTUVWXYZ;

< br $>




公共字符串RandomString（int size）

{

char [] buffer = new char [size];



for（int i = 0; i& amp; lt; size; i ++）

{

buffer [i] = _chars [_rng.Next（_chars.Length）]; < br $>
}

返回新字符串（缓冲区）;



}









MARK AS如果你得到结果答案

private readonly Random _rng = new Random();
private const string _chars = ABCDEFGHIJKLMNOPQRSTUVWXYZ ;



public string RandomString(int size)
{
char[] buffer = new char[size];

for (int i = 0; i &amp;lt; size; i++)
{
buffer[i] = _chars[_rng.Next(_chars.Length)];
}
return new string(buffer);

}
