Question

What is difference between unsafe code and unmanaged code in C#?

Answer 1

Unsafe code runs inside the CLR while un-managed code runs outside the CLR.

An example of unsafe code would be:

unsafe class MyClass
{
    private int * intPtr;
}

You can use pointers anywhere in this class.

An example of unmanaged code is:

class MyClass
{
    [DllImport("someUnmanagedDll.dll")]
    static extern int UnManagedCodeMethod(string msg, string title);

    public static void Main() 
    {
        UnManagedCodeMethod("calling unmanaged code", "hi");
    }
}

It is not necessarily unmanaged code itself, but calling it.
