Question

这可能不是一个很好的问题，但我试图将两个文件输出到一个CSV文件。我正在使用while循环来读取这两个文件，然后我调用一个方法将其全部打印出来，但是当它打印出来时，我没有得到所有的信息。这两个文件。这是我的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不输出文件中的所有信息，任何帮助将不胜感激。我会将printall();方法放在这里以防万一问题也在这里：

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}",
            QuoteString(leaseName2[i]), fieldName2[i], QuoteString2(reservoir2[i]), operator2[i], county2[i], state2[i], majo2[i], resvCatgory2[i], disRate2[i], netOil2Int2[i], netGas2Int2[i], workingInt2[i], grossWells2[i]

        i = pointers2[i];
    }
}

Answer 1

说line的第一个值被第二个覆盖是不正确的。这是因为C＃采用逻辑运算符的快捷方式。因此，如果您(A || B)且A为true，则不会调用/ {检查B。

while ((line = input2.ReadLine()) != null ||
       (line = input.ReadLine()) != null) //this is only called when the first value for line is null

也许您应该尝试将其拆分为两个while循环（或编写一个读取和输出给定输入的函数）。它会使它更具可读性，并且可以避免在完全读取input2后反复尝试阅读。{/ p>

Answer 2

您对StreamReader使用相同的字符串。声明第二个字符串“line2”，以便从第二个StreamReader“input2”中读取。

注意：你应该声明你的变量：

String line = string.Empty;

您执行此操作的方式不会初始化变量。简单的好做法。

while循环不输出两个文件中的所有信息
