创建表时不支持的异常

Question

System.NotSupportedException: Don't know about Xamarin.Forms.Color
  at SQLite.Orm.SqlType (SQLite.TableMapping+Column p, System.Boolean storeDateTimeAsTicks) 

I got this exception while creating a database in xamarin forms. I have color property as column in my table, is this exception because of that or what causes this exception?

Answer 1

You cannot have a Color field in Sqlite table. Actually only a limited data types are allowed in Sqlite database. To resolve this issue you can first convert the color object to a hex string equivalent, and then save this string to Sqlite table. And finally when you want to get the saved color, you can convert back this hex string to a Xamarin.Forms Color object by this line of code:

Color color = Color.FromHex(hexString);
