无法将长字符串插入 Orchard 中的数据库 table

Question

我创造了table

    private static void CreateTable(SchemaBuilder builder) {
        builder.CreateTable(typeof(RkeeperV7MenuRecord).Name, table => table
            .Column<int>("Id", c => c.PrimaryKey().Identity())
            .Column<int>("SpotId", c => c.NotNull())
            .Column<DateTime>("Date", c => c.NotNull())
            .Column<string>("OriginalData", c => c.NotNull().Unlimited())
            );

和 table in SQL 服务器数据库已创建（并且字符串的长度最大属性）。如果我从数据库服务器生成 SQL table 脚本，它将是这样的（因此字符串被标记为无限制）

CREATE TABLE [dbo].[Plus_Plus_SpotServerIntegration_Rkeeper_RkeeperV7MenuRecord](
    [Id] [int] IDENTITY(1,1) NOT NULL,
    [SpotId] [int] NOT NULL,
    [Date] [datetime] NOT NULL,
    [OriginalData] [nvarchar](max) NOT NULL,
PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

但是...当我尝试在 table 中插入记录时，nhibernate 抛出异常 "Error dehydrating property value for Plus.SpotServerIntegration.Rkeeper.Models.RkeeperV7MenuRecord.OriginalData" 并且内部异常是 "The length of the string value exceeds the length configured in the mapping/parameter." 我应该怎么做才能插入记录？

PS 字符串大约是 100000 个符号（它是 xml）

            _rkeeperV7MenuRepositiory.Create(new RkeeperV7MenuRecord {
                OriginalData = model.OriginalData,
                SpotId = spot.Id,
                Date = _clock.UtcNow
            });

哪里

private readonly IRepository<RkeeperV7MenuRecord> _rkeeperV7MenuRepositiory;

Answer 1

知道了！应该像这样

按属性 "StringLengthMax" 标记属性记录

public class RkeeperV7MenuRecord : DefaultEntityRecord {
    public virtual int SpotId { get; set; }
    public virtual DateTime Date { get; set; }
    [StringLengthMax]
    public virtual string OriginalData { get; set; }
}
