如何使用制表符分隔符将字符串数组写入Excel文件？

Question

我正在创建一个小应用程序,它读取制表符分隔的文本文件,进行一些更改,然后创建一个Excel 2007 .xlsx文件.我无法弄清楚如何从字符串数组中取出行并将它们写入Excel文件,使用选项卡将行分成列.我希望这是有道理的.

我有string Lines[]这样的东西:

Item1\tItem2\tItem3\tItem4
ItemA\tItemB\tItemC\tItemD
Item5\tItem6\tItem7\tItem8

我想创建一个如下所示的Excel文件:

A      B      C      D
Item1  Item2  Item3  Item4
ItemA  ItemB  ItemC  ItemD
Item5  Item6  Item7  Item8

我尝试了以下方法,但它只是将第一行Lines[]放入每一行,而不是分成列:

string Lines[] = GetLines();

Excel.Application xlApp;
Excel.Workbook xlWb;
Excel.Worksheet xlWs;
object misValue = System.Reflection.Missing.Value;

xlApp = new Excel.Application();
xlWb = xlApp.Workbooks.Add(misValue);
xlWs = (Excel.Worksheet)xlWb.Worksheets.get_Item(1);

Excel.Range c1 = (Excel.Range)xlWs.Cells[2, 1];
Excel.Range c2 = (Excel.Range)xlWs.Cells[2 + lines.Length, 1];

Excel.Range range = xlWs.get_Range(c1, c2);

range.Value = lines;
range.TextToColumns(                 
    range,
    Microsoft.Office.Interop.Excel.XlTextParsingType.xlDelimited,
    Microsoft.Office.Interop.Excel.XlTextQualifier.xlTextQualifierNone,
    false,
    true    // This is flag to say it is tab delimited
);

xlApp.Visible = true;

任何意见,将不胜感激!谢谢!

这是我目前得到的输出:

A                           B    C    D
Item1\tItem2\tItem3\tItem4
Item1\tItem2\tItem3\tItem4
Item1\tItem2\tItem3\tItem4

编辑:我已经用@ jiverson的建议更新了我的代码,现在该行已分成Excel中的列,但第一行Lines[]仍出现在Excel的每一行中.为什么？

编辑#2:这是更新的工作代码:

Excel.Application xlApp;
Excel.Workbook xlWb;
Excel.Worksheet xlWs;
object misValue = System.Reflection.Missing.Value;

xlApp = new Excel.Application();
xlWb = xlApp.Workbooks.Add(misValue);
xlWs = (Excel.Worksheet)xlWb.Worksheets.get_Item(1);

int currentRow = 2;

string[] lines = GetLines();

for (int i = 0; i < lines.Length; i++)
{
    string line = lines[i]; //get the current line

    string[] values = line.Split('\t'); //split the line at the tabs

    //
    // .. i do some things to specific values here ..
    //

    lines[i] = String.Join("\t", values); //put the updated line back together

    Excel.Range currentRange = (Excel.Range)xlWs.Cells[currentRow, 1]; //get the next row

    currentRange.Value = lines[i];  //write the line to Excel

    currentRow++;
}

Excel.Range c1 = (Excel.Range)xlWs.Cells[2, 1]; //get the first cell
Excel.Range c2 = (Excel.Range)xlWs.Cells[2 + lines.Length, 1]; //get the last cell

Excel.Range range = xlWs.get_Range(c1, c2);  //set the range as the used area

range.TextToColumns( //split the row into columns
    range,
    Excel.XlTextParsingType.xlDelimited,
    Excel.XlTextQualifier.xlTextQualifierNone,
    false,
    true    // This is flag to say it is tab delimited
);

循环添加每一行，然后在设置范围值后将文本使用到列：

    for (int i = 0; i < range.Rows.Count; i++) {
        range.Rows[i].Value = lines[i];
        range.Rows[i].TextToColumns(
            range.Rows[i],
            Microsoft.Office.Interop.Excel.XlTextParsingType.xlDelimited,
            Microsoft.Office.Interop.Excel.XlTextQualifier.xlTextQualifierNone,
            false,
            true
        );          
    }
