Can I get the name of a type at runtime?

Yes, use the GetType method of the object class (which all types inherit from). For example:
using System;

class CTest
{
class CApp
{
public static void Main()
{
long i = 10;
CTest ctest = new CTest();

DisplayTypeInfo( ctest );
DisplayTypeInfo( i );
}

static void DisplayTypeInfo( object obj )
{
Console.WriteLine( "Type name = {0}, full type name = {1}", obj.GetType(), obj.GetType().FullName );
}
}
}

produces the following output:

Type name = CTest, full type name = CTest
Type name = Int64, full type name = System.Int64

How do I calculate a MD5 hash from a string?

It is a common practice to store passwords in databases using a hash. MD5 (defined in RFC 1321 ) is a common hash algorithm, and using it from C# is easy. Here’s an implementation of a method that converts a string to an MD5 hash, which is a 32-character string of hexadecimal numbers. public string CalculateMD5Hash ( string input ) { // step 1, calculate MD5 hash from input MD5 md5 = System . Security . Cryptography . MD5 . Create ( ) ; byte [ ] inputBytes = System . Text . Encoding . ASCII . GetBytes ( input ) ; byte [ ] hash = md5 . ComputeHash ( inputBytes ) ; // step 2, convert byte array to hex string StringBuilder sb = new StringBuilder ( ) ; for ( int i = 0 ; i < hash . Length ; i ++ ) { sb . Append ( hash [ i ] . ToString ( "X2" ) ) ; } return sb . ToString ( ) ; } An example call: string hash = CalculateMD5Hash ( "abcdefghijklmnopqrstuvwxyz" ) ; …returns a s
