如何在ado.net中提交更改時跳過對象

Question

我正在使用ado.net實體數據模型。我有2個對象UserOrganization 我的問題是

User user=new User(); 

    ... 

    Organization org=new Organization() 

    db.Organizations.AddObject(org); 

    db.SubmitChanges(); // Problem is here. Because datacontext try to save user object. user object some field is empty. I don't need to save user here. How to skip user object from submitchanges 

    user.organization=org; 

db.SubmitChanges(); // I need to save user object here 

Answer 1

你需要一個使用語句範圍你的數據環境。

不完全確定你想達到什麼，但是這樣的事情？

Organization org=new Organization(); 
User user = new User(); 

using (var ctx = new YourContext()) 
{ 
    ctx.Organizations.InsertOnSubmit(org); 
    ctx.SubmitChanges(); 
    user.Organization = org;  
} 

using (var newCtx = new YourContext()) 
{ 
    // code to persist user 
}
