Before you ignore / vote-to-close this question, I consider this a valid question to ask because code clarity is an important topic of discussion, it’s essential to writing maintainable code and I would greatly appreciate answers from those who have come across this before.

I’ve recently run into this problem, LINQ queries can get pretty nasty real quick because of the large amount of nesting.

Below are some examples of the differences in formatting that I’ve come up with (for the same relatively non-complex query)

No Formatting

var allInventory = system.InventorySources.Select(src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region }).GroupBy(i => i.Region, i => i.Inventory);

Elevated Formatting

var allInventory = system.InventorySources
    .Select(src => 
        new { 
            Inventory = src.Value.GetInventory(product.OriginalProductId, true), 
            Region = src.Value.Region })
                .GroupBy(
                    i => i.Region, 
                    i => i.Inventory);

Block Formatting

var allInventory = system.InventorySources
    .Select(
        src => new 
        { 
            Inventory = src.Value.GetInventory(product.OriginalProductId, true), 
            Region = src.Value.Region 
        })
        .GroupBy(
            i => i.Region, 
            i => i.Inventory
        );

List Formatting 

var allInventory = system.InventorySources
    .Select(src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region })
    .GroupBy(i => i.Region, i => i.Inventory);

I want to come up with a standard for linq formatting so that it maximizes readability & understanding and looks clean and professional. So far I can’t decide so I turn the question to the professionals here.

    I have settled on Block formatting. It bothered my sense of “wasted space” for a while but ultimately everyone felt it was more readable by more people. As we were already putting braces on new lines it just fit better with the rest of the code. There is also less room for interpretation. We keep a cs file in the public store that has formatting examples…when somebody comes up with a unique hunk of linq we add it to the file…really helps the new guys.
