我有一种看起来像这样的方法:

// Adds an element to the TableElement table in SQL
AddToSql(TableElement deserializedObject)
{
    MyEntities entities = new MyEntities();
    entities.TableElement.AddObject(deserializedObject);
    entities.SaveChanges();
}

我尝试编写类似的方法来更新现有行,但我的方法不起作用

// Doesn't work
UpdateSql(TableElement deserializedObject)
{
    MyEntities entities = new MyEntities();
    int id = deserializedObject.id;
    TableElement elementToOverwrite = entities.TableElement
        .Single(s => s.Id == deserializedObject.Id);
    // Somehow, I want to give "elementToOverwrite" all the values in "deserializedObject"

    // I NEED TO KNOW WHAT GOES HERE.

    entities.SaveChanges();
}

更新:看起来我可以使用entities.ApplyCurrentValues("TableElement", deserializedObject)如果我的反序列化对象包含其他表中的相关行,则不会受到影响。
