How do you use the AcceptChanges() and RejectChanges() methods in a DataTable?

The AcceptChanges() method in DataTable is used to save all the changes made to the DataTable to the current version and marks the current version as the original version. This means that all uncommitted changes will be accepted and become part of the current version.

The sample code is as follows:

DataTable dt = new DataTable();
// 做一些更改
dt.Rows[0]["ColumnName"] = "New Value";

// 接受更改
dt.AcceptChanges();

The RejectChanges() method is used to discard all changes made to the DataTable and roll back to the original version.

The code example is provided below:

DataTable dt = new DataTable();
// 做一些更改
dt.Rows[0]["ColumnName"] = "New Value";

// 取消更改
dt.RejectChanges();

This allows you to manage changes to the DataTable using the AcceptChanges () and RejectChanges () methods.
