无法转换参数C＃/ SQL Server

得到错误：

无法将参数值从字符串转换为Int32

我为我的表单编写代码，最后在运行代码时出现错误。 我试图改变一切，但任何交换给我同样的错误。

我的代码：

const string sqlText = "INSERT INTO dbo.bd_formular(facultate,domeniul,specializare,forma_invatamant,d_inscriere,nume_prenume,cod,localitate,judet,tara,strada,numar,bloc,scara,etaj,apartament,sector,cod_p,data_nasterii,locul_nasterii,judet_n,tara_n,sex,stare_civila,cetatenie,cetatenie_op,etnie,incadrare,cnp,serie,numar_cnp,eliberat,e_data,studii_preuni,nume_unitate,spec_fili_profil,oras_s,judet_s,tara_s,forma_de_invatamant,medie_bac,durata_studii,data_absolvirii,tipul_diploma,seria_diploma,numarul_diploma,emis_de_catre,data_emiterii,nr_foi_matricole,introducere_date,semnatura) VALUES (@facultate,@domeniul,@specializare,@forma_invatamant,@d_inscriere,@nume_prenume,@cod,@localitate,@judet,@tara,@strada,@numar,@bloc,@scara,@etaj,@apartament,@sector,@cod_p,@data_nasterii,@locul_nasterii,@judet_n,@tara_n,@sex,@stare_civila,@cetatenie,@cetatenie_op,@etnie,@incadrare,@cnp,@serie,@numar_cnp,@eliberat,@e_data,@studii_preuni,@nume_unitate,@spec_fili_profil,@oras_s,@,@judet_s,@tara_s,@forma_de_invatamant,@medie_bac,@durata_studii,@data_absolvirii,@tipul_diploma,@seria_diploma,@numarul_diploma,@emis_de_catre,@data_emiterii,@nr_foi_matricole,@introducere_date,@semnatura)";

SQL Server表结构：

Answer 1

您正在使用如下的字符串设置int参数：

 comm.Parameters.Add(new SqlParameter("@cod", SqlDbType.Int) { Value = T4.Text }); 

您应该解析所有这些整数行中的值，例如：

 comm.Parameters.Add(new SqlParameter("@cod", SqlDbType.Int) { Value = int.Parse(T4.Text) }); 

Answer 2

为什么你不使用

 comm.Parameters.AddWithValue("@cod", T4.Text); comm.Parameters.AddWithValue("@facultate", C1.Text); comm.Parameters.AddWithValue("@domeniul", T1.Text); ... 

comm.Parameters.AddWithValue（“@ d_inscriere”，DTP1.Value）;

  ... etc
