Build & Test

The What

ObjectGraphWalker is a simple utility library that allows traversing over C# object properties, Node.js style. Under the hood, the class generates accessors that would speed up the traversal.

The How

Simply instantiate the class and use the ObjectMemberIterator::Traverse() method.

var someObject = new SomeObject();
var iterator = new ObjectMemberIterator();
iterator.Traverse(someObject, (in MemberAccessor accessor) =>
    var propertyValue = accessor.GetValue();
    prop.SetValue(/* some other value */);

Note 1: it is also possible to use predicate parameter in the ObjectMemberIterator::Traverse() method to exclude some members from the iteration. The following example iterates over all fields and properties if their name is not Foo1

var someObject = new SomeObject();
var iterator = new ObjectMemberIterator();
iterator.Traverse(someObject, (in MemberAccessor accessor) =>
    var propertyValue = accessor.GetValue();
    prop.SetValue(/* some other value */);
}, (in MemberAccessor accessor) => accessor.Name != "Foo1");

Note 2: it is possible to filter for member types (iterate only on properties or fields), like shown in the following code

iterator.Traverse(someObject, (in MemberAccessor accessor) =>
    // do some operations or mutate data
}, (in MemberAccessor accessor) => accessor.MemberType != MemberType.Property);


  • The iterator will read public and private properties and fields but will ignore any static members of the object.
  • The iterator will work on both value and reference types
  • The iterator will ignore backing fields for "auto properties" and it will ignore any compiler generated fields such as closures (unless specified in the constructor)
  • The iterator is fairly well tested by there may be some bugs. If you do see something weird, I'd appreciate an opened issue with a description 😃
