如何在使用LINQ插入后检索indentity列vaule

Question

你们有没有人能告诉我如何完成以下任务？

// Prepare object to be saved
// Note that MasterTable has MasterTableId as a Primary Key and it is an indentity column

MasterTable masterTable = new MasterTable();
masterTable.Column1 = "Column 1 Value";
masterTable.Column2 = 111;

// Instantiate DataContext
DataContext myDataContext = new DataContext("<<ConnectionStrin>>");

// Save the record
myDataContext.MasterTables.InsertOnSubmit(masterTable);
myDataContext.SubmitChanges();

// ?QUESTION?
// Now I need to retrieve the value of MasterTableId for the record just inserted above.

亲切的问候

Answer 1

在调用SubmitChanges之后,将为插入的对象分配标识值.

只需访问:

masterTable.MasterTableId
