replace this line "sd.InsertCommand = new SqlCommand("insert into DBtest VALUE(@firstname, @lastname, @mobile, @emailid)", con);"

with

sd.InsertCommand = new SqlCommand("insert into DBtest VALUES(@firstname, @lastname, @mobile, @emailid)", con);

Solution 1

It's VALUES not VALUE:

C#

sd.InsertCommand = new SqlCommand("insert into DBtest VALUE(@firstname, @lastname, @mobile, @emailid)", con);

Becomes

C#

sd.InsertCommand = new SqlCommand("insert into DBtest VALUES(@firstname, @lastname, @mobile, @emailid)", con);

However, it is a good idea to name the fields they are going to go into - that way a later database change does not screw your program up!

SQL

INSERT INTO Videos (Id, ImageFront, ImageBack, ImageCombined, Title) VALUES (@ID, @CF, @CR, @CB, @TI)

Solution 2

Take a look at the differences between quesries:

SQL

insert into DBtest VALUE(@firstname, @lastname, @mobile, @emailid)

Correct one is:

SQL

insert into DBtest (Column1, Column2, Column3, Column4)
VALUES(@firstname, @lastname, @mobile, @emailid)
