Get value of property with data member consideration

[ttruatl]

Issues

When DataMember is applied in an entity, the entityType.Key() returns a DataMember name and the MemberExpression propertyAccess = Expression.Property(odataItParameter, propertyName); was crashed because the DataMember name couldn't be found in the actual object.

For more details, I setup pageSize=100 in my ODataConfig, and I applied DataMember on the key of an entity

        [DataMember(Name = "Id")]
        [Key]
        public string Name { get; set; }

When I do the $expand on a collection of the entity, the function entityType.Key() in the SelectExpandBinder.cs returns my DataMember name id, then it could not be found at the line Expression.Property(odataItParameter, propertyName) because it's not actual a property name of the object.

Relate issue: #2443

Description

The change is to find the actual property name from the DataMemeber name if the data member name is existing. Otherwise, use the property name from the input.

What do you mean?

My suggestion is to call 'GetClrPropertyName' before calling into this method to get the real property name? Are you using non-Edm scenario?
