C# Notes

Looping threw a range

foreach(int i in Enumerable.Range(min_number, max_number))
{
    Console.WriteLine(i);
}

String to int

Convert.ToInt32(string)

Reading a text file

StreamReader sr = new StreamReader(file_path);
string data = sr.ReadLine();
sr.Close();

Checking for whole number

if((someValue % 1) == 0)
{
    Console.WriteLine("someValue is a whole number");
}

Create random int

Random random = new Random();
int randInt = random.Next(min, max);

Generate md5 hash from string

string GetMd5Hash(string inputString)
{ 
    MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();

    byte[] byteString = Encoding.UTF8.GetBytes(inputString);
    byteString = md5.ComputeHash(byteString);

    StringBuilder stringBuilder = new StringBuilder();

    foreach(byte b in byteString)
    {
        stringBuilder.Append(b.ToString("x2").ToLower());
    }

    string hashString = stringBuilder.ToString();
    return hashString;

}
