我该怎么做?

推荐答案

BindingSource 是不使用第 3 方 ORM 的唯一方法，乍一看似乎冗长，但一次更新的好处BindingSource 上的方法非常有用.

BindingSource is the only way without going for a 3rd party ORM, it may seem long winded at first but the benefits of one update method on the BindingSource are so helpful.

如果您的来源是例如用户字符串列表

If your source is say for example a list of user strings

List<string> users = GetUsers();
BindingSource source = new BindingSource();
source.DataSource = users;
dataGridView1.DataSource = source;

然后，当您完成编辑时，只需更新您的数据对象，无论是 DataTable 还是像此处这样的用户字符串列表和 BindingSource 上的 ResetBindings>;

then when your done editing just update your data object whether that be a DataTable or List of user strings like here and ResetBindings on the BindingSource;

users = GetUsers(); //Update your data object
source.ResetBindings(false);
