1. public static string CreateRandomPassword(int PasswordLength)
2. {
3. string _allowedChars = "0123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNOPQRSTUVWXYZ";
4. Random randNum = new Random();
5. char[] chars = new char[PasswordLength];
6. int allowedCharCount = _allowedChars.Length;
7. for (int i = 0; i < PasswordLength; i++)
8. {
9. chars[i] = _allowedChars[(int)((_allowedChars.Length) * randNum.NextDouble())];
10. }

Try to call the below function when you want to get random passowrd.

privatestaticstringGeneratePassword(intlength)
{
stringstrRandom=string.Empty;
try
{
stringnumbers="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
Randomobjrandom=newRandom();
stringpasswordString="";
stringopt="";
intnoofnumbers=length;
for(inti=0;i
{
inttemp=objrandom.Next(0,numbers.Length);
passwordString=numbers.ToCharArray()[temp].ToString();
strRandom+=passwordString;
}
while(opt.IndexOf(passwordString)!=-1);
}
catch(Exceptionex)
{
//Logerror
}
returnstrRandom;
}

Once you got the password, store it in Database for future purpose. Because when a new user will login it needs to verify with your stored random password.
