如何在一个视图中显示多个模型的数据？

Question

我创建了一个MVCApplication1，因为有两个这样的模型类，

StudentPersonalInfo.cs

public class StudentPersonalInfo
{
      public string StudentFirstName { get; set; }
      public string StudentLastName { get; set; }
      public int Age { get; set; }
      public string BloodGroup { get; set; }
      public string Address { get; set; }
}

第二个是

EducationQualification.cs

 public class EducationQualification
{
      public string Graduation { get; set; }
      public intGrad_Marks_obtain { get; set; }

      public DateTimeGrad_passing_year { get; set; }
      public stringPostGraduation { get; set; }

      public intPG_Marks_obtain { get; set; }
      public DateTimePG_passing_year { get; set; }
}

我想在一个视图页面中显示两个模型数据，并且在创建这两个模型后我不知道下一步该做什么。

任何人都可以帮我吗？

Answer 1

您可以根据模型创建对象：

StudentPersonalInfo myStudent = new StudentPersonalInfo();
EducationQualification myQualification = new EducationQualification();

你可以更具体一点吗？你可以做几件事，你可以用很多其他方式来操纵它们。

Answer 2

public class StudentPersonalInfo
{
      public string StudentFirstName { get; set; }
      public string StudentLastName { get; set; }
      public int Age { get; set; }
      public string BloodGroup { get; set; }
      public string Address { get; set; }
}

public class EducationQualification
{
      public string Graduation { get; set; }
      public int Grad_Marks_obtain { get; set; }

      public DateTime Grad_passing_year { get; set; }
      public string PostGraduation { get; set; }

      public int PG_Marks_obtain { get; set; }
      public DateTime PG_passing_year { get; set; }
}


public class StudentInfo
{
   public StudentPersonalInfo PersonalInfo {get;set;}
   public EducationQualification EducationalQualification {get;set;}
}

现在在视图中使用 StudentInfo 类作为模型。请参阅视图中的聚合类：

@Html.TextBoxFor(m=>m.StudentPersonalinfo.StudentFirstname)

    public int Grad_Marks_obtain { get; set; }

    public DateTime Grad_passing_year { get; set; }
    public string PostGraduation { get; set; }

    public int PG_Marks_obtain { get; set; }
    public DateTime PG_passing_year { get; set; }
}



public class StudentInfo
{
    public StudentPersonalInfo PersonalInfo { get; set; }
    public EducationQualification EducationalQualification { get; set; }
}

public class StudentDbContext:DbContext

    public DbSet<StudentPersonalInfo> StudentPersonalInfos { get; set; }

@using (Html.BeginForm())
{
    <div style="width:500px;margin:auto;">
        <fieldset>
            <legend>Student Personal Info</legend>

            <legend>Educational Qualification</legend>
            <p>Graduation: @Html.TextBoxFor(m => m.EducationalQualification.Graduation)</p>
            <p>Grad. Marks Obtained: @Html.TextBoxFor(m => m.EducationalQualification.Grad_Marks_obtain)</p>
            <p>Grad. Passing Year: @Html.TextBoxFor(m => m.EducationalQualification.Grad_passing_year)</p>
            <p>PG: @Html.TextBoxFor(m => m.EducationalQualification.PostGraduation)</p>
            <p>PG Marks Obtained: @Html.TextBoxFor(m => m.EducationalQualification.PG_Marks_obtain)</p>
            <p>PG Passing Year: @Html.TextBoxFor(m => m.EducationalQualification.PG_passing_year)</p>
        </fieldset>

        <input type="submit" value="Save"/>
    </div>
}

您可以根据自己的喜好自由进行验证并添加样式。此演示仅供参考。
