Question

我想更改身份表名称。我用Google搜索并找到了以下方法：

第一个：

protected override void OnModelCreating(ModelBuilder builder)
{
    base.OnModelCreating(builder);


    builder.Entity<ApplicationUser>(entity =>
    {
        entity.ToTable(name: "Users");
    });

    builder.Entity<ApplicationRole>(entity =>
    {
        entity.ToTable(name: "Roles");
    });

    builder.Entity<ApplicationRoleClaim>(entity =>
    {
        entity.ToTable(name: "RoleClaims");
    });

    builder.Entity<ApplicationUserRole>(entity =>
    {
        entity.ToTable(name: "UserRoles");
    });

    builder.Entity<ApplicationUserLogin>(entity =>
    {
        entity.ToTable(name: "UserLogins");
    });

    builder.Entity<ApplicationUserClaim>(entity =>
    {
        entity.ToTable(name: "UserClaims");
     });

    builder.Entity<ApplicationUserToken>(entity =>
    {
        entity.ToTable(name: "UserTokens");
    });
 }

第二个：

    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);

        builder.Entity<ApplicationUser>().ToTable("Users");
        builder.Entity<ApplicationRole>().ToTable("Roles");
        builder.Entity<ApplicationRoleClaim>().ToTable("RoleClaims");
        builder.Entity<ApplicationUserRole>().ToTable("UserRoles");
        builder.Entity<ApplicationUserClaim>().ToTable("UserClaims");
        builder.Entity<ApplicationUserToken>().ToTable("UserTokens");
        builder.Entity<ApplicationUserLogin>().ToTable("UserLogins");
    }

所有通用名称，如ApplicationUser，ApplicationRole ......都有 int 作为主键。

ApplicationDbContext 和 StartUp 如下所示

ApplicationDbContext

public class ApplicationDbContext : IdentityDbContext<ApplicationUser, ApplicationRole, int>

启动课程

       services.AddDbContext<ApplicationDbContext>(options =>
            options.UseMySql(Configuration.GetConnectionString("MySQLConnection")));

        services.AddIdentity<ApplicationUser, ApplicationRole>()
            .AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultTokenProviders();

如果您注意到，在启动课程中，我没有在AddEntityFrameworkStores<ApplicationDbContext>().上添加 int 因为，编译器错误一直显示＆＃34 ;不支持....＆＃34;。

我执行了以下操作来删除旧数据库和迁移

$ drop-database
$ remove-migration

添加新配置

$ add-migration Initial
$ update-database

我发现的结果是，只有用户和角色表被更改，而其他人没有（AspUserRoles，AspUserClaim .....）。

供参考：

我正在使用 Visual Studio 2017 。我的项目使用默认的Web应用程序，选择个人用户帐户和 .NET Core 2。我也使用 Pomela.EntityFramework.MySql 进行数据库提供商。

我的问题是：我做错了什么？或者改变了什么？

您需要告诉IdentityDbContext所有自定义类型。为了做到这一点，您需要将传递给IdentityDbContext的泛型扩展到public class ApplicationDbContext : IdentityDbContext<ApplicationUser, ApplicationRole, int, ApplicationUserClaim, ApplicationUserRole, ApplicationUserLogin, ApplicationRoleClaim, ApplicationUserToken>，如下所示：

PdfReader reader = new PdfReader(SRC);
PdfStamper stamper = new PdfStamper(reader, outputStream);
AcroFields fields = stamper.getAcroFields();

AcroFields.Item item = fields.getFieldItem(FIELDNAME);
PdfDictionary merged = item.getMerged(0);
TextField textField = new TextField(null, null, null);
fields.decodeGenericDictionary(merged, textField);
float fontSize = textField.getFontSize();

无法更改Asp身份表名称..... Asp .Net Core 2？
