原有项目中使用EF5.0 实体类
public partial class Log : BaseEntity
{
public Nullable<int> LogLevelId { get; set; }
/// <summary>
/// Gets or sets the log level
/// </summary>
public LogLevel LogLevel
{
get
{
return (LogLevel)this.LogLevelId;
}
set
{
this.LogLevelId = (int)value;
}
}
}
/// <summary>
/// Represents a log level
/// </summary>
public enum LogLevel
{
Debug = ,
Information = ,
Warning = ,
Error = ,
Fatal =
}
今天更新到EF6.1中，项目报错（An error occurred while updating the entries. See the inner exception for details），之前也没有看EF具体的更新内容，用SQL Profiler查看生成的SQL语句原来多了一个LogLevel字段，改成
public partial class Log : BaseEntity
{
//public int LogLevelId { get; set; }
/// <summary>
/// Gets or sets the log level
/// </summary>
public LogLevel LogLevelId { get; set; } }
/// <summary>
/// Represents a log level
/// </summary>
public enum LogLevel
{
Debug = ,
Information = ,
Warning = ,
Error = ,
Fatal =
}
可以保存成功了。等明天仔细看下EF5.0以后的更新内容。
