[英]DbUpdateException Whiles updating record using LINQ to Database
我一直在嘗試以 window 形式更新數據庫中的記錄,但每次單擊更新按鈕時都會出現此錯誤。
System.Data.Entity.Infrastructure.DbUpdateException: '更新條目時出錯。 有關詳細信息,請參閱內部異常。 SqlException:違反主鍵約束“PK_ad_gb_rsm”。 無法在 object 'dbo.ad_gb_rsm' 中插入重復鍵。 重復鍵值為 (100001)。 該語句已終止。
下面是我正在使用的 LINQ 代碼
private void btu_Update_Click(object sender, EventArgs e)
{
if (radioButtonMale.Checked)
{
gender = "male";
}
else if (radioButtonFemale.Checked)
{
gender = "female";
}
userID = Convert.ToDecimal(txtUserID.Text);
//ad_gb_rsm acc = DBS.ad_gb_rsm.First(s => s.ICube_id.Equals(userID));
var query = (from upd in DBS.ad_gb_rsm where upd.ICube_id == userID select upd).ToList();
foreach (var acc in query)
{
acc.user_type = comboBoxUser_Type.Text;
acc.JDate = dateTimeCrtDate.Text;
acc.title = comboBoxTitle.Text;
acc.fName = txtFname.Text;
acc.mName = txtMName.Text;
acc.lName = txtLName.Text;
acc.DOB = dateTimeDOB.Value.ToString();
acc.Gender = gender;
acc.Phone = txtPhoneNumber.Text;
acc.zip_code = txtZipCode.Text;
acc.POB = txtPOBAddress.Text;
acc.address = txtAddress.Text;
acc.email = txtEmail.Text;
acc.City = txtCity.Text;
acc.State = txtState.Text;
acc.marrital_Status = comboBoxMS.Text;
acc.NOK_Name = txtNKName.Text;
acc.NOK_Phone = txtNKNumber.Text;
acc.NOK_Address = txtNOKAddress.Text;
acc.NOKRela = txtNOKRela.Text;
acc.create_dt = dateTimeCrtDate.Value.ToString();
Image img = LogUserImage.Image;
if (img.RawFormat != null)
{
if (ms != null)
{
img.Save(ms, img.RawFormat);
acc.Picture = ms.ToArray();
}
}
acc.Dept_Sector = comboBoxDeptSector.Text;
acc.Position = comboBoxPosition.Text;
acc.JDate = dateTimeJoinDt.Value.ToString();
acc.Empl_Status = comboBoxUserStatus.Text;
acc.username = txtUsername.Text;
acc.password = txtPassword.Text;
acc.incu_copany_name = txtIncu_CompanyName.Text;
acc.createdBy = AdministratorBankLogin.AdminUserLogin.Username;
try
{
DBS.ad_gb_rsm.Add(acc);
DBS.SaveChanges();
MessageBox.Show("User Created Successfully");
}
catch (Exception exception)
{
Console.WriteLine(exception);
throw;
}
}
}
我不知道我做錯了什么。 我是新來的。
