Question

HI我在尝试将数据保存到表格[ir]时出错。[InspectionQCExceptionRuleConfig]

{＆＃34;指定的参数超出了有效范围值。\ r \ n参数名称：名称＆＃34;}

我不知道为什么，我正在尝试保存数据。但是，我能够从模型中检索数据。我粘贴了代码，上下文和域模型。如果有人知道他的。请告诉我..

          public InspectionQCExceptionRuleConfig                         SaveInspectionQCRules
            (InspectionQCExceptionRuleConfig inspectionruleconfig)
            {
                if (inspectionruleconfig != null)
                {
                    try
                    {
                        using (InspRulesData ctx = new InspRulesData())
                        {
                            inspectionruleconfig = ctx.UpdateGraph(inspectionruleconfig, map => map);
                            //ctx.InspectionQCExceptionRuleConfigs.Add(inspectionruleconfig);
                            ctx.SaveChanges();
                        }
                    }
                    catch (DbEntityValidationException ex)
                    {
                        Logging.LogError(ex);
                        throw;
                    }
                    catch (Exception ex)
                    {
                        Logging.LogError(ex);
                        throw;
                    }
                }

                return inspectionruleconfig;
            }

这是从Entity Framework

生成的域模型

    namespace DomainModel.FSEntity.InspRules
    {
        using System;
        using System.Collections.Generic;
        using System.ComponentModel.DataAnnotations;
        using System.ComponentModel.DataAnnotations.Schema;
        using System.Data.Entity.Spatial;
        using CommonLib;

        [System.CodeDom.Compiler.GeneratedCode("EF", "6.1.0")]
        [Table("ir.InspectionQCExceptionRuleConfig")]
        public partial class InspectionQCExceptionRuleConfig : BaseDomainModel
        {
            [Key]
            [StringLength(50)]
            [DatabaseGenerated(DatabaseGeneratedOption.None)]
            public string ClientNumber { get; set; }

            public bool QCOrdered { get; set; }

            public bool DwellingType { get; set; }

            public bool VacantToOccupied { get; set; }

            public bool VacantToOccupiedWithActivePreservation { get; set; }

        }
    }

这是实体框架用于保存表中的数据的上下文InspectionQCExceptionRuleConfig

        public partial class InspRulesData : CustomDbContext
        {



            public InspRulesData()
                : base("name=PlatformEntityData")
            {
                this.Configuration.LazyLoadingEnabled = false;
            }



 public virtual DbSet<InspectionQCExceptionRuleConfig>        InspectionQCExceptionRuleConfigs { get; set; }


            protected override void OnModelCreating(DbModelBuilder     modelBuilder)
            {

                modelBuilder.Entity<InspectionQCExceptionRuleConfig>()
                    .Property(e => e.ClientNumber)
                    .IsVariableLength()
                    .IsUnicode(false);
            }
        }

它也可能是由域模型中错误放置的[NotMapped]属性引起的。

实体框架{＆＃34;指定的参数超出了有效值的范围。\ r \ nParameter name：name＆＃34;}
