从Entity Framework导航属性中删除所有记录 [英] Removing all records from navigation properties in Entity Framework

问题描述

程序和学生表之间有1：N关系，EF转换为导航属性。现在我想删除这个导航学生的所有记录。
我开始这样：

  foreach（学生在program.Students）
程序。学生。删除（学生）; 
  

但是我对此有一点怀疑。

比我这样尝试：

  while（program.Students.Count> 0）
程序.Students.Remove（program.Students.ToList（）[0]）; 
  

但这似乎也很奇怪。

有没有一些更简单的方法来做，如果不是最好的方法？

解决方案

我真的不知道是否会不会工作，但我不能帮助，我很好奇。
是 program.Students.Clear（）工作？
或者也许重置它，重新初始化？
我希望它帮助你...

I have 1:N relationship between Program and Student tables which EF converted into navigation property. Now I want to delete all those records in this navigation students. I started like this:

foreach(Student student in program.Students)
program.Students.Remove(student);

But I am a little bit skeptical about this.

Than I tried this way:

while (program.Students.Count > 0)
    program.Students.Remove(program.Students.ToList()[0]);

But this seems weird too.

Is there some simpler way to do this or if not which way is the best?

解决方案

I really don't know if it's gonna work or not, but I can not help it, I'm curious. Is program.Students.Clear() working? Or maybe reset it, reinitializing it? I hope it helped you...
