C#如何把一个对象的实例保存在文件中

Posted 2020-06-21 RC7

把对象保存在文件中(格式为二进制文件):

IFormatter formatter = new BinaryFormatter();
Stream stream = new FileStream(@"D:\MyObj.bin", FileMode.OpenOrCreate, FileAccess.Write, FileShare.None);
MyObj myObj = new MyObj();
//To Do: 在这里对myObj的属性进行设置
formatter.Serialize(stream, myObj);
stream.Close();

从文件还原对象:

IFormatter formatter = new BinaryFormatter();
Stream stream = new FileStream(@"D:/MyObj.bin", FileMode.Open,FileAccess.Read, FileShare.None);
MyObj myObj = (MyObj)formatter.Deserialize(stream);
stream.Close();
