Poperty Error in MVC

Hello

Today i have faced this error :

The 'phone' property on 'Student' could not be set to a 'System.String' value. You must set this property to a non-null value of type 'System.Int32'.

And my Model class is : Student

[Table("tblStudent")]

public class Student

{

public int StudentId { get; set; }

public string name { get; set; }

public string email { get; set; }

public int phone { get; set; }

}

My Context class : StudentContext

public class StudentContext: DbContext

{

public DbSet Students { get;set; }

}

My StudentController is shown below :

public ActionResult Index(int id)

{

StudentContext stud = new StudentContext();

Student ss=stud.Students.Single(stu => stu.StudentId == id );

return View(ss);

}

Help me guys in that please soon

Know the answer? Post it — somebody with the same question will find it here.

Hi Manav

I have done the same without edmx.
It is working properly.
Issue is related to edmx only.

Please delete the table from the EDMX and re-add it.

Hi.
i think phone property contains null value so when you trying to bind value, so at that time it is trying to convert to a int it's showing error.
So you can modify it like this,

public int? phone { get; set; }
thanks.

have you tried making yout property nullable?
[Table("tblStudent")]
public class Student
{
public int? StudentId { get; set; }
public string name { get; set; }
public string email { get; set; }
public int? phone { get; set; }
}
