Gets the object. The object that describes the object. Gets or sets the value of the object. The value of the object. When this value is set, the property is set to true and is set to false. When a value is first accessed from the property, and if the value was initially stored into the object as a serialized representation using the property, the property will trigger deserialization of the underlying value. As a side effect, the property will be set to true. If this chain of events occurs in ASP.NET, and if an error occurs during the deserialization process, the error is logged using the health-monitoring feature of ASP.NET. By default, this means that deserialization errors will show up in the Application Event Log when running under ASP.NET. If this process occurs outside of ASP.NET, and if an error occurs during deserialization, the error is suppressed, and the remainder of the logic during deserialization occurs. If there is no serialized value to deserialize when the deserialization is attempted, then object will instead attempt to return a default value if one was configured as defined on the associated instance. In this case, if the property was set to either null, or to the string "[null]", then the object will initialize the property to either null for reference types, or to the default value for the associated value type. On the other hand, if property holds a valid object reference or string value (other than "[null]"), then the property is returned instead. If there is no serialized value to deserialize when the deserialization is attempted, and no default value was specified, then an empty string will be returned for string types. For all other types, a default instance will be returned by calling — for reference types this means an attempt will be made to create an object instance using the default constructor. If this attempt fails, then null is returned. While attempting to use the default value from the property, an error occurred. Either the attempt to convert property to a valid type failed, or the resulting value was not compatible with the type defined by . Gets or sets the serialized value of the object. The serialized value of a object. The serialization options for the property indicated the use of a string type converter, but a type converter was not available.
