如何将excel列从一个文件复制到另一个？
我使用Excel插件应用程序来创build可以从一个Excel文件复制列到另一个function。 这是迄今为止的代码，但是当我渲染应用程序时，程序会输出一个空白的book.xls文件。
private void button1_Click(object sender, EventArgs e) { Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application(); Excel.Workbook xlWorkBook; Excel.Workbook xlWorkBook2; Excel.Worksheet xlWorkSheet; Excel.Worksheet xlWsheet2; Excel.Range xlSourceRange; Excel.Range xlSourceRange1; Excel.Range xlDestRange; Excel.Range xlDestRange1; xlWorkBook = xlApp.Workbooks.Open("C:/../../../../../../../Test.xls"); xlWorkBook2 = xlApp.Workbooks.Open("C:/../../../../../../../Book1.xls"); //~~> Display Excel xlApp.Visible = true; //~~> Set the source worksheet xlWorkSheet = xlWorkBook.Sheets["Sheet1"]; //~~> Set the destination worksheet xlWsheet2 = xlWorkBook2.Sheets["Sheet1"]; //~~> Set the source range xlSourceRange = xlWorkSheet.Range["E15"].EntireColumn; xlSourceRange1 = xlWorkSheet.Range["D15"].EntireColumn; //~~> Set the destination range xlDestRange = xlWsheet2.Range["A2"]; xlDestRange1 = xlWsheet2.Range["B2"]; xlSourceRange.Copy(Type.Missing); xlDestRange.PasteSpecial(Excel.XlPasteType.xlPasteAll, Excel.XlPasteSpecialOperation.xlPasteSpecialOperationAdd, false, false); xlSourceRange1.Copy(Type.Missing); xlDestRange1.PasteSpecial(Excel.XlPasteType.xlPasteAll, Excel.XlPasteSpecialOperation.xlPasteSpecialOperationAdd, false, false); } 我很less不确定如何去跟踪错误，因为我目前是一个新手用户 – 使用excel库。 任何进一步的援助将不胜感激。
谢谢
朋友请使用下面的代码，使用此查询的列名实例“select sheetName from sheetName”
static void Main(string[] args) { string sourceFileName = @"C:\Test.xls"; DataTable dataTable = loadSingleSheet(sourceFileName, "Employee"); dataTable.Columns.Add("COLUMN_A"); dataTable.Columns.Remove("COLUMN_B"); } private static OleDbConnection ReturnConnection(string fileName) { return new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + "; Jet OLEDB:Engine Type=5;Extended Properties=\"Excel 8.0;\""); } private static DataTable LoadSingleSheet(string fileName, string sheetName) { DataTable sheetData = new DataTable(); using (OleDbConnection conn = ReturnConnection(fileName)) { conn.Open(); OleDbDataAdapter sheetAdapter = new OleDbDataAdapter("select columnname from [" + sheetName + "]", conn); sheetAdapter.Fill(sheetData); } return sheetData; } private static void UpdateSingleSheet(string fileName, string sheetName, DataTable dataTable) { using (OleDbConnection conn = ReturnConnection(fileName)) { conn.Open(); OleDbDataAdapter adapter = new OleDbDataAdapter(); adapter.SelectCommand = new OleDbCommand("SELECT columnname FROM [" + sheetName + "]", conn); OleDbCommandBuilder builder = new OleDbCommandBuilder(adapter); adapter.UpdateCommand = builder.GetUpdateCommand(); adapter.Update(dataTable); } }
我这样称呼它：
string destinationFileName = @"C:\TestNew.xls"; UpdateSingleSheet(destinationFileName, "Employee", dataTable);
