BsonElement attribute and custom deserialization logic with MongoDB C# driver -

consider following example:

    public class foo     {         private string _text;          [bsonelement("text"), bsonrequired]         public string text         {             { return _text; }             set             {                 _text = value;                 bar(_text);             }         }          private void bar(string text)         {             //only relevant when text set user of class,             //not during deserialization         }     } 

the setter of text property and, subsequently, method bar called both when user of class assigns new value property , during object deserialization mongodb c# driver. need ensure bar called when text property set user , not during deserialization.

i see 2 solutions don't suit me:

the first move bsonelement attribute backing field. however, far know, bsonelement attribute used in query building mongodb c# driver, lose ability use text property in queries.

the second solution make text setter private , add method through user of class set text property, , in bar method called. however, text setter used in existing solution, , i'm bit reluctant change 70+ calls across files. plus, code become less readable.

is there cleaner way separate deserialization , user-prompted property change while retaining bsonelement attribute on property?

why not create seperate property users , db same private variable, this,

public class foo {     private string _text;      [bsonelement("text"), bsonrequired]     public string textdb     {         { return _text; }         set         {             _text = value;         }     }      [bsonignore]     public string text     {         { return _text; }         set         {             _text = value;             bar(_text);         }     }      private void bar(string text)     {         //only relevant when text set user of class,         //not during deserialization     } }
