如何使用ADO.NET向数据库中插入数据

Posted 2023-02-16

。public class Student
    
        private int studentid;        public int Studentid
        
            get  return studentid; 
            set  studentid = value; 
        
        private string studentno;        public string Studentno
        
            get  return studentno; 
            set  studentno = value; 
        
        private string studentname;        public string Studentname
        
            get  return studentname; 
            set  studentname = value; 
        
        private string gender;        public string Gender
        
            get  return gender; 
            set  gender = value; 
        
        private DateTime birthday;        public DateTime Birthday
        
            get  return birthday; 
            set  birthday = value; 
        
        private int classid;        public int Classid
        
            get  return classid; 
            set  classid = value; 
        
        private int status;        public int Status
        
            get  return status; 
            set  status = value; 
        
        private string remark;        public string Remark
        
            get  return remark; 
            set  remark = value; 
        
     下面的是获取界面输入的值：namespace student
        Student stu = new Student();        private void btnCreate_Click(object sender, EventArgs e)
        
            stu.Studentname = this.txtName.Text;
            stu.Studentid = Convert.ToInt32(this.txtStudentID.Text);
            stu.Studentno = this.txtstudentNo.Text;
            stu.Gender = this.cobSex.Text;
            stu.Birthday = Convert.ToDateTime(this.dateTimePicker1.Text);
            stu.Classid = Convert.ToInt32(this.cobClass.SelectedValue.ToString());
            stu.Remark = this.txtRemark.Text;            int count = stuInsert(stu);
            if (count > 0)
            
                MessageBox.Show("添加成功！");
            
            else
            
                MessageBox.Show("添加失败！");
            
                //插入数据库的方法（可以用存储过程）public int stuInsert(Student stu)
 
           con = new SqlConnection("server=WWW-9E99F2AB2EA\\\\MYSERVER2005;database=school;uid=sa;pwd=pengxue");
            con.Open();
            comm = new SqlCommand("insert into Student(StudentID,StudentNo,StudentName,Gender,Birthday,ClassId,status,remark) values(@StudentID,@StudentNo,@StudentName,@Gender,@Birthday,@classId,@status,@remark)", con);
            comm.Parameters.Add("@StudentID", SqlDbType.Int).Value=stu.Studentid;
            comm.Parameters.Add("@studentNo",SqlDbType.VarChar).Value=stu.Studentno;
            comm.Parameters.Add("@StudentName", SqlDbType.VarChar).Value=stu.Studentname;
            comm.Parameters.Add("@Gender", SqlDbType.VarChar).Value=stu.Gender;
            comm.Parameters.Add("@Birthday", SqlDbType.DateTime).Value=stu.Birthday;
            comm.Parameters.Add("@ClassId", SqlDbType.Int).Value=stu.Classid;
            comm.Parameters.Add("@status",SqlDbType.Int).Value=1;
            comm.Parameters.Add("@remark", SqlDbType.VarChar).Value=stu.Remark;
            int i = comm.ExecuteNonQuery();
            con.Close();
            return i;
        

参考技术A insert into 表名values字段值例如: nInsert into student(student_id,student_name,department) values(“070011”,”张三”,”公共关系”); 参考技术B asp.net 三层 添加数据就加我QQ吧。 有现成的 参考技术C 不知道你有没有用三层，所以就写这样了。public class Student

private int studentid; public int Studentid

get return studentid;
set studentid = value;

private string studentno; public string Studentno

get return studentno;
set studentno = value;

private string studentname; public string Studentname

get return studentname;
set studentname = value;

private string gender; public string Gender

get return gender;
set gender = value;

private DateTime birthday; public DateTime Birthday

get return birthday;
set birthday = value;

private int classid; public int Classid

get return classid;
set classid = value;

private int status; public int Status

get return status;
set status = value;

private string remark; public string Remark

get return remark;
set remark = value;

下面的是获取界面输入的值：namespace student
Student stu = new Student(); private void btnCreate_Click(object sender, EventArgs e)

stu.Studentname = this.txtName.Text;
stu.Studentid = Convert.ToInt32(this.txtStudentID.Text);
stu.Studentno = this.txtstudentNo.Text;
stu.Gender = this.cobSex.Text;
stu.Birthday = Convert.ToDateTime(this.dateTimePicker1.Text);
stu.Classid = Convert.ToInt32(this.cobClass.SelectedValue.ToString());
stu.Remark = this.txtRemark.Text; int count = stuInsert(stu);
if (count > 0)

MessageBox.Show("添加成功！");

else

MessageBox.Show("添加失败！");

//插入数据库的方法（可以用存储过程）public int stuInsert(Student stu)

con = new SqlConnection("server=WWW-9E99F2AB2EA\\MYSERVER2005;database=school;uid=sa;pwd=pengxue");
con.Open();
comm = new SqlCommand("insert into Student(StudentID,StudentNo,StudentName,Gender,Birthday,ClassId,status,remark) values(@StudentID,@StudentNo,@StudentName,@Gender,@Birthday,@classId,@status,@remark)", con);
comm.Parameters.Add("@StudentID", SqlDbType.Int).Value=stu.Studentid;
comm.Parameters.Add("@studentNo",SqlDbType.VarChar).Value=stu.Studentno;
comm.Parameters.Add("@StudentName", SqlDbType.VarChar).Value=stu.Studentname;
comm.Parameters.Add("@Gender", SqlDbType.VarChar).Value=stu.Gender;
comm.Parameters.Add("@Birthday", SqlDbType.DateTime).Value=stu.Birthday;
comm.Parameters.Add("@ClassId", SqlDbType.Int).Value=stu.Classid;
comm.Parameters.Add("@status",SqlDbType.Int).Value=1;
comm.Parameters.Add("@remark", SqlDbType.VarChar).Value=stu.Remark;
int i = comm.ExecuteNonQuery();
con.Close();
return i;
