C# 未在数据库中更新值

我有注册表格，我在第一页插入必填字段，然后根据用户ID更新下面第二页中的一些详细信息是我的代码

        catch (Exception ex)

            throw ex;

    }

从更新sp的@id参数中删除输出参数

在c#的更新方法中设置@id的值

---

您的更新过程需要更新

where UserId=@id

但是你没有传递身份证

如果这个班

ProfileMasterBLL 

具有用户id，您可以在更新其余字段时分配该id

  if (userid != null)
        {
            prfbll.UserId = userid; //Or whatever it's called
            prfbll.FormFiledBy = RadioButtonList1.SelectedItem.Text;

如果没有，您需要更新签名

public static int update(ProfileMasterBLL profileMasterBLL, string userId)

然后将用户id也传入

这需要更改参数和存储过程

SP不应获取OUT参数（因此不应以这种方式传递）

    ALTER procedure [dbo].[sp_update]

(@id int ,@FormFiledBy varchar (50),@MaritalStatus varchar (50),@Height varchar (50),
@Religion varchar (50),@Caste varchar (100),
 @MotherTongue varchar(50),@Education varchar (100),@Occupation varchar(50),
 @CountryofResidence varchar (50),@EducationDetails varchar (100),@AnnualIncome varchar(50),
@CountryOfBirth varchar(50),@BirthPlace varchar(50),@TimeOfBirth nchar(10),@StarSign varchar (100),
@Gothram varchar (50),@Rassi varchar(50),@HavinChildren varchar(10),@PhysicalStatus varchar (100))

as
begin

update Profile_Master
 set FormFiledBy=@FormFiledBy,MaritalStatus=@MaritalStatus,Height=@Height,
Religion=@Religion,Caste=@Caste,MotherTongue=@MotherTongue,
Education=@Education,Occupation=@Occupation,CountryofResidence=@CountryofResidence,EducationDetails=@EducationDetails,
AnnualIncome=@AnnualIncome,CountryOfBirth=@CountryOfBirth,BirthPlace=@BirthPlace,TimeOfBirth=@TimeOfBirth,
StarSign=@StarSign,Gothram=@Gothram,Rassi=@Rassi,HavinChildren=@HavinChildren,PhysicalStatus=@PhysicalStatus

where UserId=@id
end

并且应该添加参数

    SqlParameter uid;
    SqlConnection conn = Generic.DBConnection.OpenConnection();
    try
    {
        SqlCommand cmdd = new SqlCommand("sp_update", conn);
        cmdd.CommandType = CommandType.StoredProcedure;
        cmdd.Parameters.AddWithValue("@Id", userId ); //Or profileMasterBLL.UserId or whatever
        cmdd.Parameters.AddWithValue("@FormFiledBy", profileMasterBLL.FormFiledBy);
        cmdd.Parameters.AddWithValue("@MaritalStatus", profileMasterBLL.MaritalStatus);
        cmdd.Parameters.AddWithValue("@Height", profileMasterBLL.Height);
        cmdd.Parameters.AddWithValue("@Religion", profileMasterBLL.Religion);
        cmdd.Parameters.AddWithValue("@Caste", profileMasterBLL.Caste);
        cmdd.Parameters.AddWithValue("@Education", profileMasterBLL.Education);
        cmdd.Parameters.AddWithValue("@Occupation", profileMasterBLL.Occupation);
        cmdd.Parameters.AddWithValue("@CountryofResidence", profileMasterBLL.CountryofResidence);
        cmdd.Parameters.AddWithValue("@EducationDetails", profileMasterBLL.EducationDetails);
        cmdd.Parameters.AddWithValue("@CountryOfBirth", profileMasterBLL.CountryOfBirth);
        cmdd.Parameters.AddWithValue("@BirthPlace", profileMasterBLL.BirthPlace);
        cmdd.Parameters.AddWithValue("@TimeOfBirth", profileMasterBLL.TimeOfBirth);
        cmdd.Parameters.AddWithValue("@StarSign", profileMasterBLL.StarSign);
        cmdd.Parameters.AddWithValue("@Gothram", profileMasterBLL.Gothram);
        cmdd.Parameters.AddWithValue("@Rassi", profileMasterBLL.Rassi);
        cmdd.Parameters.AddWithValue("@HavinChildren", profileMasterBLL.HavinChildren);
        cmdd.Parameters.AddWithValue("@PhysicalStatus", profileMasterBLL.PhysicalStatus);
        cmdd.Parameters.AddWithValue("@MotherTongue", profileMasterBLL.MotherTongue);
        cmdd.Parameters.AddWithValue("@AnnualIncome", profileMasterBLL.AnnualIncome);

同时移除这些 uid=cmdd.Parameters.Add（“@id”，System.Data.SqlDbType.Int）； uid.Direction=System.Data.ParameterDirection.Output；

---

返回cmdd.ExecuteNonQuery（）；

它不会抛出错误，但数据库中的值不会得到更新。请使用sql profiler并检查查询。我的系统中没有安装sql profiler…userid是一个标识列，它是自动递增的。我在UIID的第一页调用该方法。该代码是否正常工作并在数据库中创建必要的记录？它正常工作一段时间之后，我在字符串userid=ProfileMasterDAL.GetUserIdByEmailID（profileMasterBLL.EmailID）处得到空值；

        cmdd.CommandType = CommandType.StoredProcedure;
        cmdd.Parameters.AddWithValue("@Id", userId ); //Or profileMasterBLL.UserId or whatever
        cmdd.Parameters.AddWithValue("@FormFiledBy", profileMasterBLL.FormFiledBy);
        cmdd.Parameters.AddWithValue("@MaritalStatus", profileMasterBLL.MaritalStatus);
        cmdd.Parameters.AddWithValue("@Height", profileMasterBLL.Height);
        cmdd.Parameters.AddWithValue("@Religion", profileMasterBLL.Religion);
