C#中listview保存

我给你个实例~我是遍历集合到listview上的~所以也就是保存集合对象！
引入命名空间~using System.Runtime.Serialization.Formatters.Binary;

//...
Dictionary<string, Computer> dic = new Dictionary<string, Computer>();
//...
BinaryFormatter bf = new BinaryFormatter();

/// <summary>
/// 保存集合中的元素对象，将集合存到本地
/// </summary>
public void Save()
{
//保存集合到本地文件
FileStream fs = new FileStream("create.txt",FileMode.Create);
bf.Serialize(fs, dic);
fs.Close();
}

/// <summary>
/// 读取本地保存的文件
/// </summary>
public Dictionary<string, Computer> Read()
{
FileStream fs = new FileStream("create.txt", FileMode.Open);
dic = (Dictionary<string, Computer>) bf.Deserializ
