小编use*_*461的帖子

所以我需要得到一个商数到2个小数位,如0.33,但我是否需要一直使用双精度或者我可以使用整数除了商之外的所有东西然后只使用双或小数的商？由于商,它也在破碎.如果有人可以帮助我,我将非常感激:)

int firstnumber;
        int secondnumber;
        decimal quotient;

        firstnumber = int.Parse(inputTextBox1.Text);
        secondnumber = int.Parse(inputTextBox2.Text);

        sumLabel.Text = (firstnumber + secondnumber).ToString();

        differenceLabel.Text = (firstnumber - secondnumber).ToString();

        productLabel.Text = (firstnumber * secondnumber).ToString();

        quotient = decimal.Parse(quotientLabel.Text);
        quotient = (firstnumber / secondnumber).tostring;

我想知道如何使用StreamWriter将文本文件写入桌面上的特定位置,例如C:\ Users\tommy\desktop\transaction \？

    private void CreateTransaction_Click(object sender, EventArgs e)
    {
        StreamWriter outputFile;
        outputFile = File.CreateText (TID.ToString()+".txt");

        outputFile.WriteLine("Investor :" +" " + InvestorNameLabel.Text);
        outputFile.WriteLine("Initial Amount" + " " +AmountLabel.Text);
        outputFile.WriteLine("Date Invested" +" " +DateLabel.Text);
        outputFile.WriteLine("Period Chosen" + " "+DaysInvestedLabel.Text);
        outputFile.WriteLine("Rate Chosen" + " " + RateLabel.Text);
        outputFile.WriteLine("Total Interest" + " " +InterestAmountLabel.Text);
        outputFile.WriteLine("Transaction Number :" + " " + TransactionIDLabel.Text);
        outputFile.Close();

        MessageBox.Show("Transaction file for Transaction: " + TransactionIDLabel.Text + "Was Created", "Transaction File");
