我有两个表,Profile 和 ProfileCategory
ProfileId INT IX
UserId UNIQUEIDENTIFIER PK (For one-to-one mapping with aspnet_membership)
CompanyName
Description
ProfileCategory
CategoryId
ProfileId
当我使用 PLINGO 生成代码时,出现以下错误
运算符“==”不能应用于“int?”类型的操作数 和“System.Guid”运算符“==”不能应用于“int?”类型的操作数 和'System.Guid'
我深入研究了生成的代码和以下内容..
[System.Diagnostics.DebuggerNonUserCode]
[System.CodeDom.Compiler.GeneratedCode("CodeSmith", "5.0.0.0")]
private void OnProfileList1Remove(Profile entity)
{
SendPropertyChanging(null);
var profileCategory = ProfileCategoryList.FirstOrDefault(c => c.CategoryId == CategoryId
&& c.ProfileId == entity.UserId);
ProfileCategoryList.Remove( profileCategory);
SendPropertyChanged(null);
}
所以生成的代码好像要比较索引和主键
我可以手动更改代码,但在重新生成时它将被更改回来。
有谁知道为什么会这样?
谢谢
这是来自 dbml 的配置文件片段
