如何从集合中获取一个属性并将其分配给数组？

Question

I thought this would be easy, but I can't seem to get it to work.

I have a model in my Entity Framework project called _context.Galaxy.

It contains a bunch of different properties, but I only want to retrieve the name and create a string array of all the galaxy names in the database.

Here is my code:

var allGalaxyNames = _context.Galaxy
    .Select(x => new
    {
        GalaxyName = x.Name.ToString()
    }).ToArray();


    string[] AllGalaxys = allGalaxyNames

I keep getting this error no matter what I try:

 Cannot implicitly convert type '<anonymous type: string GalaxyName>[]' to 'string[]'

How can I get this to work?

Thanks!

You don't need the anonymous object, just return a string from the Select .

string[] allGalaxyNames = _context.Galaxy
    .Select(x => x.Name.ToString())
    .ToArray();
