更新数据时出错

Error converting data type nvarchar to int.

我的代码是

 public bool UpdateData(MemberInfo memberinfo)
        {
            SqlCommand cmd = DataConnection.GetConnection().CreateCommand();
            cmd.CommandText = "prcUpdateMemberInfo";
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.Add(new SqlParameter("@MemberFirstName", memberinfo.MemberFirstName));
            cmd.Parameters.Add(new SqlParameter("@MemberMiddleName", memberinfo.MemberMiddleName));
            cmd.Parameters.Add(new SqlParameter("@MemberLastName", memberinfo.MemberLastName));
            cmd.Parameters.Add(new SqlParameter("@FatherName", memberinfo.FatherName));
            cmd.Parameters.Add(new SqlParameter("@MotherName", memberinfo.MotherName));
            cmd.Parameters.Add(new SqlParameter("@FamilyHeadName", memberinfo.FamilyHeadName));
            cmd.Parameters.Add(new SqlParameter("@DOB", memberinfo.DOB));
            cmd.Parameters.Add(new SqlParameter("@EducationLevelID", memberinfo.EducationLevelID));
            cmd.Parameters.Add(new SqlParameter("@EducationFieldID", memberinfo.EducationFieldID));
            cmd.Parameters.Add(new SqlParameter("@BloodGroupID", memberinfo.BloodGroupID));
            cmd.Parameters.Add(new SqlParameter("@OccupationTypeID", memberinfo.OccupationTypeID));
            cmd.Parameters.Add(new SqlParameter("@Gender", memberinfo.Gender));
            cmd.Parameters.Add(new SqlParameter("@GotraID", memberinfo.GotraID));
            cmd.Parameters.Add(new SqlParameter("@SectID", memberinfo.SectID));
            cmd.Parameters.Add(new SqlParameter("@MaritalStatus", memberinfo.MarritalStatus));
            cmd.Parameters.Add(new SqlParameter("@HouseNumber", memberinfo.HouseNumber));
            cmd.Parameters.Add(new SqlParameter("@StreetName", memberinfo.StreetName));
            cmd.Parameters.Add(new SqlParameter("@Area", memberinfo.Area));
            cmd.Parameters.Add(new SqlParameter("@LandMark", memberinfo.LandMark));
            cmd.Parameters.Add(new SqlParameter("@StateID", memberinfo.StateID));
            cmd.Parameters.Add(new SqlParameter("@CountryID", memberinfo.CountryID));
            cmd.Parameters.Add(new SqlParameter("@CityID", memberinfo.CityID));
            cmd.Parameters.Add(new SqlParameter("@EmailAddress", memberinfo.EmailAddress));
            cmd.Parameters.Add(new SqlParameter("@PhoneNumber", memberinfo.PhoneNumber));
            cmd.Parameters.Add(new SqlParameter("@UserId", memberinfo.UserId));          
            cmd.Parameters.Add(new SqlParameter("@IsSubmit", memberinfo.IsSubmit));
            bool ans = cmd.ExecuteNonQuery() > 0;
            cmd.Dispose();
            DataConnection.CloseConnection();
            return ans;

，程序是

Answer 1

正如我在评论中所说，在类定义中，PhoneNumber是一个字符串，但存储过程需要一个整数。这是你的问题。

我会将存储过程和基础数据表更改为VARCHAR（30）或类似大小，因为可以使用带字母字符的电话号码。否则，如果您完全确定相反，则将类声明更改为整数。

Answer 2

您的程序@PhoneNumber int应该是@PhoneNumber varchar(50)或其他一些varchar长度。

错误：使用代码未处理SqlException？
