typeof: how to get type from string

try
{
    // Get the type of a specified class.
    Type myType1 = Type.GetType("System.DateTime");
    Console.WriteLine("The full name is {myType1.FullName}.");

    // Since NoneSuch does not exist in this assembly, GetType throws a TypeLoadException.
    Type myType2 = Type.GetType("NoneSuch", true);
    Console.WriteLine("The full name is {myType2.FullName}.");
}
catch(TypeLoadException e)
{
    Console.WriteLine(e.Message);
