I believe you should be able to pass an array in for your "expected" object and get the behavior you're after:

myResult.ShouldLookLike(() =>
new [] {
new MyObject(){
//You can even make sure resultId is populated
ResultId = Any.NonDefaultValueOf<Guid>(),
ObjectName = "result name 1",
ObjectValue = "object value 1"
},
new MyObject(){
//You can even make sure resultId is populated
ResultId = Any.NonDefaultValueOf<Guid>(),
ObjectName = "result name 2",
ObjectValue = "object value 2"
}
}

Sorry Matt, it doesn't work.
This error show up when compile : "Cannot convert lambda expression to type 'System.Collections.Generic.List<MyObject>' because it is not a delegate type"

I checked source code on GitHub:

"var newArrayExpression = matchFunc.Body as NewArrayExpression;"

ShouldLookLike method convert body of Expression to NewArrayExpression but myResult is a list, it doesn't match generic type declaration of method.
So I modified code to:

myResult
.ToArray()/This convert list to array?
.ShouldLookLike(() =>
new [] {
new MyObject(){
//You can even make sure resultId is populated
ResultId = Any.NonDefaultValueOf<Guid>(),
ObjectName = "result name 1",
ObjectValue = "object value 1"
},
new MyObject(){
//You can even make sure resultId is populated
ResultId = Any.NonDefaultValueOf<Guid>(),
ObjectName = "result name 2",
ObjectValue = "object value 2"
}
})

This works :)
