Json and Circular Reference Exception

by

Update:

Do not try to use NonSerializedAttribute, as the JavaScriptSerializer apparently ignores it.

Instead, use the ScriptIgnoreAttribute in System.Web.Script.Serialization.

public class Machine
{
    public string Customer { get; set; }

    // Other members
    // ...
}

public class Customer
{
    [ScriptIgnore]
    public Machine Machine { get; set; }    // Parent reference?

    // Other members
    // ...
}

This way, when you toss a Machine into the Json method, it will traverse the relationship from Machine to Customer but will not try to go back from Customer to Machine.

The relationship is still there for your code to do as it pleases with, but the JavaScriptSerializer (used by the Json method) will ignore it.
