今日站立会议，未照相，各自完善了代码，我将自己的代码进行了完善和修改，在原来的基础上进行了部分的修改

public partial class Form当日消费情况 : Form

{

public Form当日消费情况()

{

InitializeComponent();

}

bool flag = false;

private void Form当日消费情况_Load(object sender, EventArgs e)

{

label1.Text = "消费情况如下";

if (File.Exists(sp))

{

using (FileStream fs = new FileStream(sp, FileMode.OpenOrCreate, FileAccess.Read))

{

byte[] buffer = new byte[1024 * 1024 * 5];

int x = fs.Read(buffer, 0, buffer.Length);

}
