var gg = request
    .Number_Name
    .Keys
    .Intersect(_context.Users.Select(x => x.Phone))

I tried something like this, but it doesnt work.

Answer 1

try this code :

1 - Get keys

var keys = request
    .Number_Name
    .Keys
    .Intersect(_context.Users.Select(x => x.Phone));

2 - Get new dictionary

var newDic = request
    .Number_Name
    .Where(k => keys.Contains(k.Key))
    .ToDictionary(k => k.Key, v => v.Value);

Or

var newDic = request
    .Number_Name
    .Keys
    .Intersect(_context.Users.Select(x => x.Phone))
    .ToDictionary(k => k, v => request.Number_Name[v]);
