C# 在 mysql 中插入复选框的值而不使用 checklistbox

Question

我在 C# 中使用 MetroFramework，它没有 Checklistbox。有人可以帮助我如何在不使用 checklistbox 的情况下在 mysql 中插入复选框的值吗？

这是我搜索过的代码示例，但它不起作用。

CheckBox[] checkboxes = new CheckBox[] { newRIadhd, newRIallergy, newRIanemia, newRIasthma, newRIautism, newRIdepression, newRIdownSyndrome, newRIdyscalculia, newRIDyslexia, newRIepilepsy, newRIheartFailure, newRIhypertension, newRIintDis, newRImigraine, newRIspinaBifida};

            List<string> checked = new List<string>();
foreach (Checkbox checkbox in checkboxes) {
  if (checkbox.Checked) {
    checked.Add(checkbox.Text);
  }
}
string checkedText = String.Join(", ", checked);

这是我用于插入新数据的所有代码并且它正在运行。但我被“@morRI”困住了，因为它有很多需要保存的复选框。上面的代码只是一些网站上的副本。

string insertQuery = "INSERT INTO db_personal(per_image,per_Fname,per_Mname,per_Lname,per_Sname,per_birthDate,per_birthPlace,per_age,per_gender,per_nationality,per_religion,per_ethnicity,per_conNum,per_emailAdd,per_civStatus,per_spouseName,per_spouseOccupation,per_childName,per_childGender,per_childAge,per_city,per_barangay,per_division,per_blockOrStreet,per_houseNumber,per_zipCode) VALUES(@per_image,@per_Fname,@per_Mname,@per_Lname,@per_Sname,@per_birthDate,@per_birthPlace,@per_age,@per_gender,@per_nationality,@per_religion,@per_ethnicity,@per_conNum,@per_emailAdd,@per_civStatus,@per_spouseName,@per_spouseOccupation,@per_childName,@per_childGender,@per_childAge,@per_city,@per_barangay,@per_division,@per_blockOrStreet,@per_houseNumber,@per_zipCode); INSERT INTO db_academic(aca_elementary,aca_elemYearGrad,aca_elemHonor,aca_secondary,aca_secYearGrad,aca_secHonor,aca_seniorHigh,aca_SHyearGrad,aca_SHhonor,aca_ALS,aca_certificateSch,aca_certificateName,aca_tertiary,aca_mermbershipName,aca_membershipPos,aca_probation) VALUES(@aca_elementary,@aca_elemYearGrad,@aca_elemHonor,@aca_secondary,@aca_secYearGrad,@aca_secHonor,@aca_seniorHigh,@aca_SHyearGrad,@aca_SHhonor,@aca_ALS,@aca_certificateSch,@aca_certificateName,@aca_tertiary,@aca_mermbershipName,@aca_membershipPos,@aca_probation); INSERT INTO db_family(fam_parStatus,fam_fatherFN,fam_fatherMN,fam_fatherLN,fam_fatherSN,fam_fatherDec,fam_fatherAdd,fam_fatherEdu,fam_fatherOccu,fam_motherFN,fam_motherMN,fam_motherLN,fam_motherPN,fam_motherDec,fam_motherAdd,fam_motherEdu,fam_motherOccu,fam_guardianName,fam_guardAge,fam_guardOccu,fam_guardAdd,fam_guardRel,fam_guardConNum,fam_siblingName,fam_sibRel,fam_sibAge,fam_sibStat,fam_sibOccu,fam_sibConNum,fam_busKind,fam_busLocation,fam_busIncome) VALUES(@fam_parStatus,@fam_fatherFN,@fam_fatherMN,@fam_fatherLN,@fam_fatherSN,@fam_fatherDec,@fam_fatherAdd,@fam_fatherEdu,@fam_fatherOccu,@fam_motherFN,@fam_motherMN,@fam_motherLN,@fam_motherPN,@fam_motherDec,@fam_motherAdd,@fam_motherEdu,@fam_motherOccu,@fam_guardianName,@fam_guardAge,@fam_guardOccu,@fam_guardAdd,@fam_guardRel,@fam_guardConNum,@fam_siblingName,@fam_sibRel,@fam_sibAge,@fam_sibStat,@fam_sibOccu,@fam_sibConNum,@fam_busKind,@fam_busLocation,@fam_busIncome); INSERT INTO db() VALUES()";

您插入数据时似乎出现一些错误。看 MySQL Insert into multiple tables? (Database normalization?) .

上面的示例代码将 checkboxes 中每个选中的复选框的逗号分隔字符串(Text-property)分配给checkedText。如果没有选中任何复选框，则checkedText 为空字符串。

要将字符串写入数据库，您必须将其分配给相应的 mysql 参数(@mor_RI)并完成最后一条插入语句(带参数分配)。

cmd.Parameters.AddWithValue("@mor_RI", checkedText);
