Introduction to the method of implementing deep copy and initial refresh of DataGridView through serialization in C#
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();
});The above is the detailed content of Introduction to the method of implementing deep copy and initial refresh of DataGridView through serialization in C#. For more information, please follow other related articles on the PHP Chinese website!

The difference between multithreading and asynchronous c#
Apr 03, 2025 pm 02:57 PM
The difference between multithreading and asynchronous is that multithreading executes multiple threads at the same time, while asynchronously performs operations without blocking the current thread. Multithreading is used for compute-intensive tasks, while asynchronously is used for user interaction. The advantage of multi-threading is to improve computing performance, while the advantage of asynchronous is to not block UI threads. Choosing multithreading or asynchronous depends on the nature of the task: Computation-intensive tasks use multithreading, tasks that interact with external resources and need to keep UI responsiveness use asynchronous.

C# vs. C : History, Evolution, and Future Prospects
Apr 19, 2025 am 12:07 AM
The history and evolution of C# and C are unique, and the future prospects are also different. 1.C was invented by BjarneStroustrup in 1983 to introduce object-oriented programming into the C language. Its evolution process includes multiple standardizations, such as C 11 introducing auto keywords and lambda expressions, C 20 introducing concepts and coroutines, and will focus on performance and system-level programming in the future. 2.C# was released by Microsoft in 2000. Combining the advantages of C and Java, its evolution focuses on simplicity and productivity. For example, C#2.0 introduced generics and C#5.0 introduced asynchronous programming, which will focus on developers' productivity and cloud computing in the future.
