朋友们,我正在制作一个 Windows 窗体应用程序,其中我在 sql-server-2008 中创建了一个存储过程,然后像这样在 Windows 窗体中创建了一个外部类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Jain_milan.Common
{
public class Personal
{
string name, fathername, mothername, familyhead, dateofbirth,educationlvl, education, blood, gotra, panth, marrital;
public string Educationlvl
{
get { return educationlvl; }
set { educationlvl = value; }
}
public string Panth
{
get { return panth; }
set { panth = value; }
}
public string Gotra
{
get { return gotra; }
set { gotra = value; }
}
public string Blood
{
get { return blood; }
set { blood = value; }
}
public string Education
{
get { return education; }
set { education = value; }
}
public string DateOfBirth
{
get { return dateofbirth; }
set { dateofbirth = value; }
}
public string FamilyHead
{
get { return familyhead; }
set { familyhead = value; }
}
public string MotherName
{
get { return mothername; }
set { mothername = value; }
}
public string FatherName
{
get { return fathername; }
set { fathername = value; }
}
public string Name
{
get { return name; }
set { name = value; }
}
public string Marrital
{
get { return marrital; }
set { marrital = value; }
}
}
}
我为所有参数创建了get set函数在另一个外部类中,我定义了所有这样的存储过程
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Jain_milan.DataAction
{
public enum InsertStoredProcedure
{
insertpersonal,
insertressicontact,
insertoccupcontact,
insertspouse,
insert1children,
insert2children,
insert3children,
insert4children,
insert5children
}
}
将其插入数据库后,我再次创建了一个单独的类并像这样传递参数
public class InsertAction
{
public bool Insertpersonal(Personal per)
{
SqlCommand cmd = Database.GetConnection().CreateCommand();
cmd.CommandText=InsertStoredProcedure.insertpersonal.ToString();
cmd.CommandType= CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("@Name",per.Name));
cmd.Parameters.Add(new SqlParameter("@FatherName",per.FatherName));
cmd.Parameters.Add(new SqlParameter("@MotherName",per.MotherName));
cmd.Parameters.Add(new SqlParameter("@FamilyHead",per.FamilyHead));
cmd.Parameters.Add(new SqlParameter("@DateOfBirth",per.DateOfBirth));
cmd.Parameters.Add(new SqlParameter("@EducationLevel", per.Educationlvl));
cmd.Parameters.Add(new SqlParameter("@Education",per.Education));
cmd.Parameters.Add(new SqlParameter("@Blood",per.Blood));
cmd.Parameters.Add(new SqlParameter("@Gotra",per.Gotra));
cmd.Parameters.Add(new SqlParameter("@Panth",per.Panth));
cmd.Parameters.Add(new SqlParameter("@Marrital",per.Marrital));
bool ans = cmd.ExecuteNonQuery() > 0;
cmd.Dispose();
Database.CloseConnection();
return ans;
}}
然后在提交按钮上,我完成了提交操作的编码....
private void submit_addbtn_Click(object sender, EventArgs e)
{
try
{
//personal data insert
Personal per = new Personal();
per.Name = nametxt.Text;
per.FatherName = f_nametxt.Text;
per.MotherName = m_nametxt.Text;
per.Gotra = gotra_txt.Text;
per.Panth = panthcb.Text;
per.FamilyHead = fhntext.Text;
per.Educationlvl = edulvlcb.Text;
per.Education = educb.Text;
per.Blood = bloodcb.Text;
per.Marrital = MarritalStatus;
per.DateOfBirth = (day + '/' + month + '/' + year).ToString();
if (new InsertAction().Insertpersonal(per))
{
MessageBox.Show("Personal Insertion Happen ");
}
else
{
MessageBox.Show(" Personal Insertion does not Happen ");
}
}}
在运行程序时,它显示的错误是
过程或函数“插入个人”需要未提供的参数“@educationlvl”
但是我已经像所有其他参数一样提供了它,然后发生了什么问题.....请解决这个问题。请请
