private void SetTablePrimaryKey<T>(T entity)
{
PropertyInfo pkProp = typeof(T).GetProperties().Where(p => p.GetCustomAttributes(typeof(KeyAttribute), false).Length >0).FirstOrDefault();
//主键名称
var keyName = pkProp.Name;
//实体类中主键的值
//var keyId = pkProp.GetValue(entity).ToString();
foreach (PropertyInfo p in entity.GetType().GetProperties())
{
if (p.Name.ToString() == keyName)
{
p.SetValue(entity, Guid.NewGuid().ToString(),null);
}
}
}
实体类中的ID要加KeyAttribute
public class InterfaceVoyage : BaseEntity { [KeyAttribute] public string Id { get; set; } }
