Question

我正在使用Asp.net Identity来授权登录。我可以注册帐户，但我无法使用它们登录。调用此函数时，我收到500错误（无效列名）。

    try
    {
         user = await userManager.FindAsync(context.UserName, 
            context.Password);

    }catch(Exception e)
    {
        //Invalid column name 'UserId'.
    }

另外，我使用此链接手动创建数据库..

How do I create the asp.net Identity tables manually with migrations?

我更改了测试数据库中的UserId字段以匹配您的AspNetUserClaims表。通常，该字段名为UserId，而不是像您的User_Id。当我做了这个小改动并试图从项目中获取令牌时，结果是一个无效的列名称＆＃39; UserId＆＃39;。

要解决此问题，请更改AspNetUserClaims表以从该字段中删除下划线。它应该有希望工作。基本上，FindAsync在获取用户和所有相关表时无法找到该列。

c＃Identity userManager.FindAsync无效的UserId
