获取：

public Object Get(SalesOrderDetailsGet request)
        {
            SalesOrderDataProcess sODP = new SalesOrderDataProcess(Db);
            SalesOrder salesOrderTemp = sODP.GetSalesOrderById(request.SalesOrderId);

数据层：

 public SalesOrder GetSalesOrderById(Guid id)
        {
            return _dbConnection.SingleById<SalesOrder>(id);
        }

运行停在上面的方块

return _dbConnection.SingleById<SalesOrder>(id);

非常感谢。

这是一个 common SQL Server exception，表明它无法将字符串值转换为 uniqueidentifier（即 GUID）。

返回并确保您 Table 中的所有数据都具有 uniqueidentifier 字段的值，并且该值是有效的 GUID。

ServiceStack - OrmLite（可能） - 从字符串转换为 uniqueidentifier 时转换失败

ServiceStack - OrmLite (probably) - Conversion failed when converting from a character string to uniqueidentifier
