The following editor will bring you an article on how to implement deep copy through serialization in C# and implement initial refresh of DataGridView. The editor thinks it is quite good, so I will share it with you now and give it as a reference for everyone. Let's follow the editor and take a look.

The cell in the DataGridView in winfrom will modify its data source when editing. If we encounter such a situation, refresh the data source to the original state. At this time Either the data source is re-obtained for binding, or the data of the original file is copied and then bound. The copy method is introduced here.

The approximate code is as follows:

1. The target pair needs to be serialized and implement ICloneable Interface：

[Serializable]
public class DtoColumn : ICloneable2.实现接口方法Clone： 


public object Clone()
{
    using (MemoryStream ms = new MemoryStream(capacity))
    {
      object CloneObject;
      BinaryFormatter bf = new BinaryFormatter(null, new StreamingContext(StreamingContextStates.Clone));
      bf.Serialize(ms, this);
      ms.Seek(0, SeekOrigin.Begin);      
      CloneObject = bf.Deserialize(ms);       
      ms.Close();
      return CloneObject;
    }
}

3. Refresh by copying a copy of data:

private List < dto.DtoColumn > DeepCloneData(List < dto.DtoColumn > rawdata) {
  return rawdata.Select(x = >x.Clone()).Cast < dto.DtoColumn > ().ToList()
}

this.dataGridView1.DoThreadPoolWork(() = >
{
  this.dataGridView1.DataSource = DeepCloneData(CloneInitialColumnData);
  this.dataGridView1.Refresh();
});
