while 循环不输出两个文件中的所有信息

这可能不是一个很好的问题，但我正在尝试将两个文件输出到一个CSV文件中。我使用 while 循环来读取这两个文件，然后调用一个将其全部打印出来的方法，但是当它打印出来时，我无法获取两个文件中的所有信息。这是我while循环代码：

private void mergeBtn_Click(object sender, EventArgs e)
{


    if (System.IO.File.Exists("OUTPUT.csv"))
    {
        System.IO.File.Delete("OUTPUT.csv");
        output = new System.IO.StreamWriter("OUTPUT.csv");
    }
    else
    {
        output = new System.IO.StreamWriter("OUTPUT.csv");
    }

    String[] head = File.ReadAllLines(textBox3.Text); //header file array
    foreach (string h in head)
    {
        output.WriteLine(QuoteString(h));
    }

    input = new StreamReader(textBox1.Text);
    input2 = new StreamReader(textBox2.Text);

    String line, templeaseName2, tempfieldName2, tempreservoir2, tempoperator2, tempcounty2, tempstate2, tempmajo2, tempReserveCat2, tempDiscountRate2, tempnetOil2Int2, tempnetGas2Int2, tempworkingInt2
        , tempgrossWells2, tempultOil2, tempultGas2, tempgrossOil2, tempgrossNGL2, tempgrossGas2, tempnetOil2, tempnetGas2, tempnetNGL2, temprevToInt2, tempoperExpense2, temptotInvest2, temprevOil2
        , temprevGas2, tempoperatingProfit2, temprevNGL2, tempDiscNetInc, tempseqNum2, tempwellID2, tempincASN2, templifeYears2, tempownQual2, tempprodTax2, tempAdValorem2;
    while ((line = input2.ReadLine()) != null || (line = input.ReadLine()) != null)
    {
        templeaseName2 = line.Substring(0, 33);
        tempfieldName2 = line.Substring(33, 33);
        tempreservoir2 = line.Substring(66, 21);
        tempoperator2 = line.Substring(87, 25);
        tempcounty2 = line.Substring(112, 21);
        tempstate2 = line.Substring(133, 2);
        tempmajo2 = line.Substring(136, 3);
        tempReserveCat2 = line.Substring(141, 4);
        tempDiscountRate2 = line.Substring(146, 6);
        tempnetOil2Int2 = line.Substring(152, 10);
        tempnetGas2Int2 = line.Substring(162, 10);
        tempworkingInt2 = line.Substring(172, 10);
        tempgrossWells2 = line.Substring(182, 6);
        tempultOil2 = line.Substring(188, 14);
        tempultGas2 = line.Substring(202, 14);
        tempgrossOil2 = line.Substring(216, 14);
        tempgrossNGL2 = line.Substring(230, 14);
        tempgrossGas2 = line.Substring(244, 14);
        tempnetOil2 = line.Substring(258, 14);
        tempnetGas2 = line.Substring(272, 14);
        tempnetNGL2 = line.Substring(286, 14);
        temprevToInt2 = line.Substring(300, 14);
        tempoperExpense2 = line.Substring(314, 14);
        temptotInvest2 = line.Substring(328, 14);
        temprevOil2 = line.Substring(342, 14);
        temprevGas2 = line.Substring(356, 14);
        tempoperatingProfit2 = line.Substring(370, 14);
        temprevNGL2 = line.Substring(384, 14);
        tempDiscNetInc = line.Substring(398, 14);
        tempseqNum2 = line.Substring(412, 6);
        tempwellID2 = line.Substring(418, 6);
        tempincASN2 = line.Substring(425, 6);
        templifeYears2 = line.Substring(432, 6);
        tempownQual2 = line.Substring(439, 9);
        tempprodTax2 = line.Substring(449, 13);
        tempAdValorem2 = line.Substring(462, 14);
        add(templeaseName2, tempfieldName2, tempreservoir2, tempoperator2, tempcounty2, tempstate2, tempmajo2, tempReserveCat2, tempDiscountRate2, tempnetOil2Int2, tempnetGas2Int2, tempworkingInt2,
            tempgrossWells2, tempultOil2, tempultGas2, tempgrossOil2, tempgrossNGL2, tempgrossGas2, tempnetOil2, tempnetGas2, tempnetNGL2, temprevToInt2, tempoperExpense2, temptotInvest2, temprevOil2,
            temprevGas2, tempoperatingProfit2, temprevNGL2, tempDiscNetInc, tempseqNum2, tempwellID2, tempincASN2, templifeYears2, tempownQual2, tempprodTax2, tempAdValorem2);
    }
    printAll();
    input.Close();
    input2.Close();
    output.Close();
}

我真的不确定为什么它没有输出文件中的所有信息，任何帮助将不胜感激。我将把我的printall();方法放在这里，以防万一这也是问题所在：

public void printAll()
{
    output.WriteLine();
    output.WriteLine();
    output.WriteLine();
    output.WriteLine("Lease Name, Field Name, Reservoir, Operator, County, ST, Majo, Resv Cat, Discount Rate, Net Oil Interest, Net Gas Interest, Working Interest, Gross Wells, Ultimate Oil, Ultimate Gas, Gross Oil, Gross NGL, Gross Gas, Net Oil, Net Gas, Net NGL, Revenue To Int., Oper. Expense, Total Invest., Revenue Oil, Revenue Gas, Operating Profit, Revenue NGL, Disc Net Income, SEQ, Well ID, INC ASN, Life Years, Own Qual, Production Tax, Ad Valorem Tax");
    int i = listHead2;
    //Loops until the end of the list, printing out info
    while (i != -1)
    {
        output.WriteLine("{0}, {1}, {2}, {3}, {4}, {5}, {6}, {7}, {8}, {9}, {10}, {11}, {12}, {13}, {14}, {15}, {16}, {17}, {18}, {19}, {20}, {21}, {22}, {23}, {24}, {25}, {26}, {27}, {28}, {29}, {30}, {31}, {32}, {33}, {34}, {35}",

        i = pointers2[i];
    }
