Hi All,
Some time we need to generate random sequence of alphanumeric /nemeric/character for password/key etc. Below is static function which takes integer as parameter for the length of the output.

private static string RandomNumberGenerator(int length)
{
RandomNumberGenerator rng = RandomNumberGenerator.Create();
char[] chars = new char[length];
string validChars = "abcdefghijklmnopqrstuvwxyzABCEDFGHIJKLMNOPQRSTUVWXYZ1234567890"; //based on your requirment you can take only alphabets or number
for (int i=0; i< length; i++)
{
byte[] bytes = new byte[1];
rng.GetBytes(bytes);
Random rnd = new Random(bytes[0]);
chars[i] = validChars[rnd.Next(0,61)];
}
return (new string(chars));
}

Hi All,

This function is used to convert file into byte array. some time we require to convert file into byte to save into database or send to other system using remoting.

private byte [] StreamFile(string filename)
{
FileStream fs = new FileStream(filename, FileMode.Open,FileAccess.Read);

// Create a byte array of file stream length
byte[] ImageData = new byte[fs.Length];

//Read block of bytes from stream into the byte array
fs.Read(ImageData,0,System.Convert.ToInt32(fs.Length));

//Close the File Stream
fs.Close();

return ImageData; //return the byte data
}
