How to assign a string to an integer field via reflection
<p>So this is the code which makes me sad : </p>

<pre><code>private static void AssignId(object entity, string id)
        {
            var idFieldInfo = entity.GetType().GetProperties().SingleOrDefault(it =&gt; it.GetCustomAttributes(typeof(KeyAttribute), false).Any());
            if (idFieldInfo != null)
            {
                var type = idFieldInfo.PropertyType;

                if (type == typeof(byte))
                {
                    idFieldInfo.SetValue(entity, Convert.ToByte(id), null);
                }
                else if (type == typeof(short))
                {
                    idFieldInfo.SetValue(entity, Convert.ToInt16(id), null);
                }
                else if (type == typeof(int))
                {
                    idFieldInfo.SetValue(entity, Convert.ToInt32(id), null);
                }
                else if (type == typeof(long))
                {
                    idFieldInfo.SetValue(entity, Convert.ToInt64(id), null);
                }
                else if (type == typeof(sbyte))
                {
                    idFieldInfo.SetValue(entity, Convert.ToSByte(id), null);
                }
                else if (type == typeof(ushort))
                {
                    idFieldInfo.SetValue(entity, Convert.ToUInt16(id), null);
                }
                else if (type == typeof(uint))
                {
                    idFieldInfo.SetValue(entity, Convert.ToUInt32(id), null);
                }
                else if (type == typeof(ulong))
                {
                    idFieldInfo.SetValue(entity, Convert.ToUInt64(id), null);
                }
            }
        }
</code></pre>

<p>Is there a smarter way to assign a string value corresponding integer</p>
