Test 测试用-一些C#里面用的东西

『清除LISTBOX』

orderListBox.Items.Clear();

『I/O操作』

文件头

StreamWriter fileStreamWriter;

StreamReader fileStreamReader;

文件中

fileStreamWriter = new StreamWriter("custInfo.txt");

读写

fileStreamWriter.WriteLine(nameTextBox.Text);

nameTextBox.Text = fileStreamReader.ReadLine();

『读取并判断文件是不是结束了』

string genderString;

if (fileStreamReader.Peek() != -1)

{

nameTextBox.Text = fileStreamReader.ReadLine()；

genderString = fileStreamReader.ReadLine();

if (genderString == "Male")

{

maleRadioButton.Checked = true;

}

else

{

femaleRadioButton.Checked = true;

}

『列表』

while (fileStreamReader.Peek() != -1)

{

custListBox.Items.Add("Name: " + fileStreamReader.ReadLine());

custListBox.Items.Add("NRIC: " + fileStreamReader.ReadLine());

custListBox.Items.Add("Address: " + fileStreamReader.ReadLine());

custListBox.Items.Add("Phone: " + fileStreamReader.ReadLine());

custListBox.Items.Add("Gender: " + fileStreamReader.ReadLine());

custListBox.Items.Add("---------------------------------");

}

『计算价格』

cfmLable.Text = nameTextBox.Text + " booking is:\n" + hoursTextBox.Text + " hour/s of " + strRoom + " room.\n" + "Total cost: " + fltTotalCost.ToString("c") + strMember;

『从文件读取』

StreamReader fileStreamReader = new StreamReader("C:\\test\\test.txt");

If(fileStramReader.Peek()!=1)

{

nameLable.Text = fileStreamReader.ReaderLine();

phoneNolable.Text=fileStreamReader.Reader();

}
