Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded.

EF6進行Insert操作的時候提示錯誤

Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded.

1：確認model中是否外鍵關聯問題

　　解決方案：外鍵關聯不要修改外鍵表的數據，可以暫是設置NotMapped或者外鍵model=null處理

2：確認model對應數據庫表中id是否設置主鍵且主鍵自增長

　　解決方案：數據庫設置主鍵並主鍵自增長

 

這是目前我遇到的兩種情況，如果還沒有解決您的問題，請留言吧！
