[英]How can we run the excel macro of an existing Excel sheet using C#?
[英]Establish Connection to existing Excel Application and Run an Excel macro C#
所有,
抱歉,如果这是一个非常基本的问题,并且已经被问过,我主要使用VBA / JAVA编写。 但是,我正在从事的项目需要C#脚本。 它执行3个简单步骤:
定位已打开的Excel工作簿。 文件路径:
\\ Csdatg04 \\ psproject \\ Robot \\ Peoplesoft到LV \\主文件-不要使用\\向LV Template.xlsm的交易
用早先在自动化中已检索到的三个变量填充单元格A1,A2和A3。
运行存储在上述文件路径中的宏宏名称“ ControlMacroACT”
我开发的代码在下面,但是在上面确定的每个阶段中,我都遇到错误(可能是基本错误)。
错误1:这行代码是要打开一个工作簿,我希望这是针对已处于活动状态的工作簿的。
错误2:找不到工作表
public void RunActualsMacro(string Filepath, string Period, String FiscalYear)
{
//~~> Define your Excel Objects
Excel.Application xlApp = new Excel.Application();
Excel.Workbook xlWorkBook;
//~~> Start Excel and open the workbook.
//Error 1
xlWorkBook = xlApp.Workbooks.Open("\\Csdatg04\\psproject\\Robot\\Peoplesoft To LV\\Master Files - Do not use\\Transactions into LV Template.xlsm");
// Populat Cells A1,A2,A3 with string variables
// Error 2 Worksheet not found
worksheet.Rows.Cells[1, 1] = Filepath;
worksheet.Rows.Cells[2, 1] = Period;
worksheet.Rows.Cells[3, 1] = FiscalYear;
//~~> Run the macro ControlMacroAct
xlApp.Run("ControlMacroACT");
//~~> Clean-up: Close the workbook
xlWorkBook.Close(false);
//~~> Quit the Excel Application
xlApp.Quit();
}
任何帮助将非常感激。
您需要使用Marshal.GetActiveObject,并且此代码大致正确,但是目前无法测试。
public void RunActualsMacro(string Filepath, string Period, String FiscalYear)
{
//~~> Define your Excel Objects
Excel.Application xlApp = null;
Excel.Workbook xlWorkBook;
//~~> Start Excel and open the workbook.
//handle errors below
try {
xlApp = (Excel.Application) System.Runtime.InteropServices.Marshal.GetActiveObject("Excel.Application");
} catch {
//perhaps exit - or throw??
}
xlWorkBook = xlApp.Workbooks["Transactions into LV Template.xlsm"];
// Populat Cells A1,A2,A3 with string variables
Excel.Worksheet ws = xlWorkBook.Worksheets["Sheet1"] //what the tab name of sheet
ws.Cells[1, 1] = Filepath;
ws.Cells[2, 1] = Period;
ws.Cells[3, 1] = FiscalYear;
//~~> Run the macro ControlMacroAct
xlApp.Run("ControlMacroACT");
//~~> Clean-up: Close the workbook
xlWorkBook.Close(false);
//~~> Quit the Excel Application
xlApp.Quit();
}
