Int32 for ASP.NET Core claim value

Question

It looks like claims are way to go with ASP.NET Core (3.1) authorization, but my question is how can we have integer values not only strings? I want to store some IDs in the claims:

var userid = 123;  // try "123"
var claimsIdentity = new ClaimsIdentity(CookieAuthenticationDefaults.AuthenticationScheme);
claimsIdentity.AddClaim(new Claim(ClaimTypes.NameIdentifier, userid, ClaimValueTypes.Integer32));

Or any better way to do it? TIA

The claims can only be represented as strings. So you can convert userid to string , and on other side decode token , get claim and convert to int again if needed .
