推荐答案
根据评论:
Microsoft.AspNetCore.Identity.UserStoreBase.ConvertIdFromString(字符串ID).
Microsoft.AspNetCore.Identity.UserStoreBase.ConvertIdFromString(string id).
原来我有一个使用旧guid格式的cookie，简单的解决方法是 清除Cookie.
Turns out I had a cookie using the old guid format, simple fix was to clear cookies.
问题在于，您以前的某些登录可能是在ID为GUID时完成的.您将其更改为int，因此现在它不再知道如何处理GUID.最简单的解决方案是删除cookie，有效地注销您并强迫您再次登录(改用int).
The issue is that some of your previous logins were likely done when the ID was a GUID. You changed it to int, and so now it doesn't know how to handle the GUID any more. The simplest solution will be to delete your cookies, effectively logging you out and forcing you to login again (using int instead).
