输入的字符串格式不正确。在System.Number.StringToNumber''在System.Int32.Parse（String s）

Question

我正在尝试将新记录保存到我的sql服务器数据库中。但是我不断收到这个错误

System.FormatException：输入字符串的格式不正确。在MOH处System.Int32.Parse（String s）处System.Number.ParseInt32（String s，NumberStyles style，NumberFormatInfo info）在System.Number.StringToNumber（String str，NumberStyles选项，NumberBuffer＆number，NumberFormatInfo info，Boolean parseDecimal） .SID'......'CauseOfDeath.aspx.cs：第206行

我尝试检查数据库和模型的数据类型兼容性，但似乎一切都匹配。

DateTime DOBdate = Convert.ToDateTime（txtDOB.Text）;          DateTime DODdate = Convert.ToDateTime（txtDOD.Text）;

     DateTime DLSDate = Convert.ToDateTime(txtDLS.Text);
     DateTime DOCDate = Convert.ToDateTime(txtDOC.Text);

               try
               {
                   Databases.COD cod = new Databases.COD()
                   {
                        Facility = ddlFacility.SelectedValue.ToString(),

                        DOB = Convert.ToString(DOBdate),
                        DOD = Convert.ToString(DODdate),

                        NOC = txtNameOfCertifier.Text,
                        DOC = Convert.ToString(DOCDate),
                        Condition_Leading = txtcondition1.Text,
                        Condition_Leading_Period = int.Parse(TxtCondition1Period.Text),
                        Condition_Leading_ICD_Code = txtCondition1ICDCode.Text,
                        Antecedent1 = txtAntecedent.Text,
                        Antecedent_Period = int.Parse(txtAntecedentPeriod.Text),
                        Antecedent_ICD_Code = txtAntecedentICDCode.Text,
                        Antecedent2 = txtAntecedent1.Text,
                        Antecedent2_Period = int.Parse(txtAntecedent1Period.Text),
                        Antecedent2_ICD_Code = txtAntecedent1Period.Text,
                        Antecedent3 = txtAntecedent2.Text,
                        Antecedent3_Period = int.Parse(txtAntecedent2Period.Text),
                        Antecedent3_ICD_Code = txtAntecedent2ICDCode.Text,
                        Other_Condition = txtotherconditions.Text,
                        Otehr_Condition_ICD_Code = txtOtherICD.Text,
                };
                      healthDC.CODs.Add(cod);

我需要将这些值保存到我的表中。
