I want to upload Excel file from Webpage and save the data to SQL database and then retrieve the data from db to display in tabular format USING Entity Framework in MVC

Sample Data for Attendence

                foreach (DataRow row in dt.Rows)
                {

                    
                    entities4.Students.Add(new Student
                    {
                       // Student_Id = long.Parse(row["Student_Id"].ToString()),
                        Student_Name = row["Student_Name"].ToString(),
                        NIOS_Enrolment_No = row["NIOS_Enrolment_No"].ToString()
                                                                       
                    });
                }
                entities4.SaveChanges();

If it doesn't have to be a real-time process, you could create an SSIS package to import the uploaded file, create a SQL server job to run the package, schedule that job to run every N minutes, and simply let the user hit refresh on the web site whenever he wants.

I know it sounds like a lot of work, but it really isn't, and that's precisely the way I would approach it myself.

Your sample data has the column name "Student Name".

You are trying to read the value from a column called "Student_Name".

Those are not the same. The first has a space, whilst the second has an underscore.

Similarly, "NIOS_Enrolment_No" is not the same as "NIOS EnrolmentNo.".

The column names you read need to precisely match the column names from the source file. Debug your code and check the actual column names from the source file, and then fix your code to use the correct column names.
