我正在嘗試使用代碼優(yōu)先方法為在線考試系統(tǒng)創(chuàng)建一個數(shù)據(jù)庫。我已經(jīng)創(chuàng)建了我的數(shù)據(jù)模型，我的上下文類，setInitializer在文件中添加了我的方法Global.asax，添加了我的連接字符串。但是仍然沒有創(chuàng)建數(shù)據(jù)庫。真的需要一些幫助。我的連接字符串：<connectionStrings> <add name="ExamDbContext" connectionString="server=LAPTOP-JJKI9JN7; Initial Catalog=OnlineExamSystem; Integrated Security=true;" providerName="System.Data.SqlClient"> </add> </connectionStrings>LAPTOP-JJKI9JN7是我的 SSMS 服務(wù)器名稱學(xué)生表：using System;using System.Collections.Generic;using System.ComponentModel.DataAnnotations;using System.Linq;using System.Web;namespace Online_Exam_System.Models{ public class TBL_STUDENT { public int S_ID { get; set; } [Display(Name = "Student")] [Required(ErrorMessage = "The field is required")] public string S_NAME { get; set; } [Display(Name = "Password")] [Required(ErrorMessage = "The field is required")] public string S_PASSWORD { get; set; } [Display(Name = "Marks")] [Required(ErrorMessage = "The field is required")] public Nullable<int> S_MARKS { get; set; } }}

設(shè)置初始化程序后，通過訪問某處的上下文或強制它來強制它運行：
Database.SetInitializer(new NullDatabaseInitializer<ExamDbContext>());
// Forces initialization of database on model changes.
using (var context= new ExamDbContext ()) {
? ?context.Database.Initialize(false);
} ? ?
