推荐答案

亲爱的朋友，

您可以在.net中生成相同的随机数:-

Dear Friend,

you can generate a random number in .net for the same:-

Random rnd = new Random();
long number = Convert.ToInt64(rnd.Next(1,10000));

可以根据要生成的随机数增加上限范围.

另外，您还可以生成一个唯一的16位GUID代码，该代码始终是唯一的

The upper range can be increased according as to how big random number you want to generate.

Else you can also generate a unique GUID code of 16 digits, which is always unique

Guid g;
// Create and display the value of two GUIDs.
g = Guid.NewGuid();

使用以下JavaScript生成10个字符的代码.

Use following javascript to generate code of 10 character.

<script language="javascript" type="text/javascript">
        function GetString(txtCode) {
            document.getElementById(txtCode).value = RamdomString(10);
            return false;
        }
        //Random String Generator//
        function RamdomString(intLen) {
            var strRet = "";
            var iCntr = 0;
            var rndNo = 0;
            var arrCharacters = new Array("A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", "1", "2", "3", "4", "5", "6", "7", "8", "9", "0", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z");
            for (iCntr = 0; iCntr < intLen; iCntr++) {
                rndNo = Math.floor((61 - 1 + 1) * Math.random() + 1);
                strRet = strRet + arrCharacters[rndNo];
            }
            return strRet;
        }
    </script>
