Serialize objest as string value (as if calling ToString() on it) with c# driver

[Sharas gpavarde]

Hi,

I have a datastructure in c#

public class ResourceSpec
{
        public string TypeName
        {
            get;
            private set;
        }

        public HashSet<ResourceProperty> Properties
        {
            get;
            private set;
       }

}



public class ResourceProperty
{
     public string Val
     {
         get;
         private set;
     }

}

I want it to be serialized into:

{TypeName: 'blabla', Properties: ['value1', 'value2', 'value3' ]}

Instead of 

 

{TypeName: 'blabla', Properties: [{Val: 'value1'}, {Val: ' value2'}, {Val: ' value3'}] }

How can I do that?

Hey Sharas. Are you still having troubles with this?  If you want to change how an object is serialized into a string, override the ToString() method to produce a string in the desired format.

Hi,

Thats what I did, but that object is held by parent object that I am serializing. And I have no easy way to tell serializer "When you serialize that child object call ToString on it".

Hey Sharas. Based on the code you've given us, you could change

public HashSet<ResourceProperty> Properties { get; private set; }

to

public HashSet<string> Properties { get; private set; }

and get the desired serialization. However, if you want a more complicated structure for ResourceProperty than just a string value that will also serialize correctly when embedded in the parent document, look at implementing IBsonSerializer for ResourceProperty. You'll find the interface in the C# API docs under the MongoDB.Bson.Serialization Namespace.
