[Question] Results.Merge() where TValue is a collection

[forrestab]

I have a requirement to merge multiple results of type Result<IEnumerable<T>>. Here is an example of what Im trying to do:

Result<IEnumerable<SomeDto>> result = Result.Ok(Enumerable.Empty<SomeDto>());

if (someCondition)
{
    Result<IEnumerable<SomeDto>> dbResult = await CallSomeDbFunc();
    result = Result.Merge(result, dbResult);
}

if (result.IsSuccess && someCondition)
{
    // run another db function and merge with `result`
}

With the above code, Result.Merge is returning Result<IEnumerable<IEnumerable<SomeDto>>>>. What I would rather it return is the input's result type.

In order to achieve what I want, Im using ToResult to "unwrap" the return from Result.Merge.

Result.Merge(result, dbResult).ToResult(result => result.SelectMany(value => value));

Is this the recommended way or have I missed a method signature somewhere?
