解决方案

如果您正在使用Entity Framework（您的标签表示）一个href =https://stackoverflow.com/questions/450601/intercept-entity-saving-with-ado-net-net-entities-framework>这个StackOverflow文章应该能够帮助你。基本上你可以拦截SavingChanges事件，并且做任何你想要的。将它放在一个部分类中，将以下方法添加到对象上下文中：

  partial void OnContextCreated（）
 { 
 SavingChanges + = DoWhatYouMust; 
} 
 
 private void DoWhatYouMust（object sender，System.EventArgs e）
 {
} 
  

Hi i'm looking for a asp.net mvc callback for elaborate data before save a model.

In rails there is before_save.

Thanks

解决方案

If you are using Entity Framework (which your tag indicates), then this StackOverflow post should be able to help you out. Basically you can intercept the SavingChanges event, and do whatever you want. Put this in a partial class that adds the following methods to your object context:

partial void OnContextCreated()
{
    SavingChanges += DoWhatYouMust;
}

private void DoWhatYouMust(object sender, System.EventArgs e)
{
}
