这就是让我伤心的代码:
private static void AssignId(object entity, string id)
{
var idFieldInfo = entity.GetType().GetProperties().SingleOrDefault(it => 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);
}
}
}
有没有更聪明的方法将字符串值分配给对应的整数
